Today, wifi technology is very much used. This is what makes it more massive and also with very advanced technology and also with a variety of diverse technologies. One of the existing technologies of wifi today is outdoor wifi. Outdoor wifi has an antenna, this is what will be discussed. What is an outdoor wifi antenna?
Outdoor wifi is indeed very common you find now. This is wifi technology that makes wifi accessible anytime and anywhere. Outdoor wifi of course Omni WIFI is the best solution for outdoor. In addition, outdoor wifi is also different from indoor wifi.

Wireless or Wifi networks use radio frequency signals instead of cables to connect your devices such as computers, printers, and smartphones to the Internet and to each other. Wifi signal can be picked up by wireless enabled devices such as laptops or tablets within a certain distance in any direction.
Internet connectivity occurs through a wireless router. When you access Wifi, you are connected to a wireless router that allows your Wifi compatible device to interact with the Internet.
Wifi uses electromagnetic waves to communicate data that travels on two main frequencies: 2.4Ghz (802.11b) and 5Ghz (802.11a). For years, 2.4Ghz was a popular choice for Wifi users, as it worked with most major devices and was cheaper than the 11a.
Wifi was invented and first released to consumers in 1997 when a committee called 802.11 was formed.
This led to the creation of IEEE802.11, which refers to a set of standards that define communications for wireless local area networks (WLANs). Following this, the basic specifications for WiFi were created, allowing the wireless transfer of two megabytes per second of data between devices.
This sparked the development of prototype equipment (routers) to comply with IEEE802.11, and in 1999, Wifi was introduced for home use. And this is when until now wifi continues to grow, one of which is an outdoor wifi antenna.
In 2003, the faster speeds and ranges of previous versions of WiFi were combined to create the 802.11g standard. Routers are also getting better, with higher power and longer range than ever before. WiFi is starting to catch up – competing with the fastest wired connection speeds.
2009 saw the final version of 802.11n, which was even faster and more reliable than its predecessor. This increase in efficiency is attributed to ‘Multiple input multiple output’ (MIMO) data, which uses multiple antennas to improve communication at both the transmitter and receiver. This allows for a significant increase in data without requiring higher bandwidth or transmit power.
This is where the wifi technology becomes easier and more widespread, such as with the Wifi SSID, express Wifi, and Wifi Tents.
At a basic level, Wifi is a way to get broadband internet to a device using a wireless transmitter and radio signal. Once the transmitter receives data from the internet, it converts the data into radio signals that can be received and read by Wifi-enabled devices. Information is then exchanged between the transmitter and the device.
The popularity of wireless LANs is a major testament to their convenience, cost efficiency, and ease of integration with other networks and network components. The majority of computers sold to consumers today are equipped with all the necessary wireless LAN technology.
There are various benefits of Wifi that you can get if you use it, including:
1. To Share Files and Folders
One of the benefits of wifi is being able to share files and folders wirelessly. Wireless sharing allows multiple users to access files without downloading them separately; for example: a shared music folder that allows more than one person to listen to the same file.
2. To Connect with the Internet
Of course, a benefit of wifi is being able to connect to the internet. The internet is very helpful in many ways, be it for finding information, working, or doing remote activities.
3. Sync Mobile Without USB
Transferring files is something we do all the time, especially for users who have multiple devices. And for Android users, the most common way to transfer files from PC to Android is by using a USB cable. But sometimes you may encounter some situations, such as unavailability of USB cable, failed to install USB driver on your PC, or even corrupted USB port.
With wifi technology, you can easily sync your cellphone without using a USB.
4. Transferring Videos and Photos from a Digital Camera
Wifi technology can be used to transfer videos and photos from digital cameras to other devices such as PCs, laptops, and even smartphones. Without using cables anymore, this is one of the summary of wifi technology.
5. Printing on a Printer
Printing on a printer can also be done wirelessly and using wifi technology. Very much and profitable isn’t it if you want to print something but the printer location is far away? It can still be reached wirelessly by using wifi.
Functions of Wifi
There are various functions of Wifi that you need to know. Of course, this is something you can use on a daily basis.
1. Wireless Communication Media
Have you ever thought how you can chat with your family? phone with your colleagues? of course you no longer use the cable is not it? This is one of the functions of wifi, as a medium of wireless communication that is easy, cheap, and also fast.
2. Modem from Smartphone
Wifi also has a function as a modem that comes from a smartphone. Yes, now, you can connect to the internet just by connecting your PC or laptop with a smartphone that is connected to the internet. So, later the device connected to the smartphone can also be connected to the internet, and the smartphone is a modem.
3. Faster Internet Speed
Did you know that wifi technology has a function to be able to connect to the internet faster? Yes, wifi technology is currently being continuously developed, one of which is an outdoor wifi antenna to be able to connect to the internet quickly.
4. Sharing Data Between Devices
Wifi can also be used to share data between devices. One of them is using a hotspot. Sharing data between devices means that this is a function of the wifi transmitter as well as the wifi receiver and channeling the internet to various devices in the vicinity so that they can connect to the internet.
5. Connecting Devices to a Network
If you already have high-speed (broadband) Internet service in your home, it’s fairly easy to set up your own home wireless network. Commonly known as Wifi, wireless networks allow you to connect laptops, smartphones, and other mobile devices to your home Internet service without an Ethernet cable.
This is the function of wifi which is very helpful in forming a network at home and can be connected to each other. Don’t forget to add a wifi password to keep your connection safe.
Wifi Advantages and Disadvantages
Everything has its pros and cons, including wifi. While this is generally seen as an advantageous technology, there can also be downsides to having wifi.
1. Advantages of Wifi
The following are the advantages of wifi that you can feel:
Mobility is the biggest advantage of WiFi. Wireless networks are well known and implemented for mobility. Broadband and other cable technologies cannot be used outside the Fixed premises. But Wifi, you can use it on the go.
Convenience and Hassle Free
Using WiFi is more convenient than using wired technology. Also, it’s not a hassle. You don’t need a lot of cables to connect devices to each other.
Multiple Connection Support
Wifi Support Multiple Connections. It supports about 30 devices simultaneously.
The cost of WiFi deployment is almost zero. You don’t have to pay for a router. You don’t need any additional cables or adapters.
Wireless Technology provides more opportunities for manufacturing and development companies.
2. Lack of Wifi
Meanwhile, the disadvantages of wifi itself are as follows:
The biggest disadvantage of WiFi is its Security. Even with password, WiFi network is not Secure.
WiFi speed is less compared to wired network. Connection speed decreases as Connection increases.
Obstacles and Distractions
Wifi Network is experiencing Constraints and interruptions throughout your home or office.
Some studies say Wifi causes health effects. The wave or wifi signal is said to have an adverse effect on the skin and other parts.
WiFi coverage is limited. You can’t Wifi if two devices are at a great distance. WiFi range is limited to under 10m.
In the world of Wifi, it is very common to find these two types of wifi, namely indoor wifi and outdoor wifi. Everything has its own use depending on the situation and conditions. Then, is the definition of the two the same? Of course the same because both are wifi.
Then, what does it mean?
The first type of wifi is indoor wifi. This type of wifi is indeed very common you find, and you can really tell with the naked eye and without thinking if it’s a wifi transmitter when you see it in the corner of the room, whether it’s at home, a cafe, or in various public places.
Understanding Indoor Wifi and Its Characteristics
Indoor wifi, as the name implies, is a wifi device that functions to connect a computer or similar device to the online world that is installed in the room.
The hallmark of indoor wifi is that the coverage is quite small and has a signal that is not too strong because it is blocked by building walls and a certain distance. To access the online world, generally access points (or known as wifi hotspots) are installed in strategic locations in buildings that allow people to reach the wifi hotspot easily and comfortably.
The next type of wifi is outdoor wifi. Maybe this is a device that you rarely find. However, this tool is actually very widely used in various office areas or city parks that use it to make it a public hotspot.
Understanding Outdoor Wifi and Its Characteristics
As for outdoor wifi, it is a wifi device installed in an open and wide area with the aim of spreading access to the virtual world over a wide range.
If indoor wifi is installed in a building or near a building, outdoor wifi has different characteristics by installing it in a high, open place, and using additional devices such as towers for installation.
Difference Between Indoor and Outdoor Wifi
based on the definition of outdoor WiFi antenna above, there are some differences between indoor WiFi and outdoor WiFi as follows:
The first difference between an outdoor WiFi antenna and an indoor WiFi antenna is the WiFi coverage distance.
Indoor WiFi has a narrower range than outdoor WiFi. So if you find WiFi that is only able to reach one building, it is certain that it is indoor WiFi. Meanwhile, if you find WiFi with a very wide range up to thousands of meters away, it is definitely outdoor WiFi.
Tools Used and Forms
The range distance determines the difference between an outdoor WiFi antenna and an indoor WiFi antenna.
Usually the use of indoor WiFi usually uses fairly simple equipment such as access points and cables. As for outdoor WiFi, of course, it has a different shape and has additional tools.
Existence of Buildings and Additional Tools
In accordance with the use of the device in the outdoor WiFi antenna as above, it can only be installed indoors which is only an access point and a cable to access the internet.
Meanwhile, outdoor WiFi uses additional buildings in the form of towers and tools in the form of antennas and lightning rods so that they can be used to access the internet safely and comfortably.
The more complicated the installation, the more expensive the outdoor WiFi will be.
Usually the use of indoor WiFi is not expensive to install, which is estimated at around 300 thousand per pcs, while the outdoor WiFi price has a price of over 1 million rupiah.
Important Part In Wifi
In understanding the role of wifi, we need to know some important parts of WiFi as follows:
WiFi in modern times has experienced a rapid increase in terms of technology that is used in the business sector.
Large office spaces with many employees will certainly result in heavy WiFi traffic, while small offices with limited users are more likely to have extended WiFi coverage.
Short Definition of Access Point
An access point is a device that creates a wireless local area network or WLAN, which is used in large buildings.
The access point is connected to a wired router, switch, or hub using a WiFi SSD or Ethernet cable.
If you want to enable WiFi ssid access in the reception area but the WiFi doesn’t have a router within range then you can use an ethernet cable through the office ceiling back to the server room.
Access Point Functions
The main function of the access point is an internet signal transmitter. In addition, other functions include complex connectivity settings such as the following functions:
- Manage access on a device based on MAC address. MAC Address is a unique identifier owned by the device’s network card.
- As a Dynamic Host Configuration Protocol (DHCP) server so that it can add an IP address to each connected device.
- Replaces the use of a hub that connects a wireless local network together with a wired network.
- Provides security features WEP (Wired Equivalent Privacy) and WAP (Wireless Application Protocol). This is the security of the wireless network along with the key match authentication provided to the client at the access point. While WAP is a security method created to complement the WEP method along with adding decryption.
Router is a computer hardware that may already be recognized by many people. This type of router network hardware has quite a lot of types with different functions by type.
Router short definition
Like the use of an outdoor WiFi antenna, of course, it also requires a router. Routers basically have location table data from IPs that are used to communicate with other routers to determine the best path to access the internet.
A router is a physical or virtual internet network device designed to receive, analyze, and forward data packets between computer networks.
The task of the router performs its role in checking the destination IP address of the given internet data packet based on the header table and carrying out the redirection made for the transfer of internet packets to available devices.
Router is also defined as a device that connects two or more networks of data packets that are connected to each other.
And also the router is able to serve the management of traffic between networks that forward data packets to the destination IP address. Once the router allows multiple devices using the same internet connection.
The function of the router is as a network hardware, which means hardware that is able to support the transmission process of an existing network or network.
Router in Indonesian is a barrier which means computer hardware capable of running the routing process.
This routing process is a process where the router can add additional routes or paths, so that a network or network can get to the user.
For example, in one office, there is a server that is the center of the network, with thousands of computer users located in far-flung areas.
Therefore, a router is used to be able to provide additional routes from the server to the user’s computer.
The network pad that points to the user’s computer or can also be directed to other devices such as bridges, hubs, switches, modems, access points, and others.
Types of Routers Based on the Mechanism
The types of routers themselves have a lot of variety. But mechanically routers are divided into two types, namely static and dynamic. Here’s the explanation.
Static Router / Static Router
The first type of router is a static router or commonly called a static router which can work to direct the blocking process from a network.
The mechanism in the blocking process involves what we know as the routing table or the blocking table.
In using a static router, the blocking process on this router is administered manually by an administrator.
All forms of blocking through the routing table are run manually by the administrator, where the administrator is fully responsible for carrying out all forms of the blocking process, from triggering new roads or routes, deleting routes, moving routes, and so on.
The admin staff will take full control of the permissions or permissions that exist on the router.
Dynamic routers are the opposite of static routers which have the advantage of automatic and dynamic router configuration settings.
So that once the dynamic router configuration will work automatically as instructed by the admin.
Dynamic router will do the blocking or routing to the user that has been determined, through the path or route that has been determined, able to delete the path that is not used, create a new routing path to a new user, deny routing access to certain users, and much more. All processes are carried out dynamically by the router automatically
This wireless router is a type of static or dynamic router. Which is in accordance with the name, namely the wireless router works without cables, relying on a wireless connection using air media.
This router type is not specific, which means it can be a static router or a dynamic router. As the name implies, a wireless router is a type of router that works without using cables, and relies on a wireless connection using air media. This wireless router is currently quite widely used because it provides a lot of convenience.
Understanding the client in a computer network is a device or tool that uses the resources provided by the server.
In principle, the client and server in a network system are interconnected devices.
The definition of a client is a computer that is used to access services from the server. And the client is also often referred to as a workstation.
In a computer network the number of clients there is more than one computer which is adjusted to the number of users in an agency or company.
Brief understanding of clients
Client computers generally have various applications that can make it easier for users to connect information and data. In addition, the client computer is usually added together with other applications such as office applications (Office), browsers, players and others.
For hardware problems, the client computer is not as high as the server computer. This is because the workload that is run by the client computer is not as high as the server computer. Some examples of facilities that can be requested by a client computer include file, data, printer and internet access.
Client Functions in Computer Networks
State the function of the client computer which has several functions, including:
To Access Data And Information Provided By The Server Computer
The main function of the client computer is to access the data and information provided by the server. And also each client has certain access rights that access the required services.
As a work computer
The client computer is also often used as a work computer outside of the services provided by the server computer.
The client computer can also be an administrator for other computers on a network in accordance with the access rights granted by the server pc to the client pc.
A WiFi adapter or also called a WiFi adapter is a tool that is used on a computer or laptop device to have access to the available WiFi connection in the vicinity.
WiFi adapter has radio waves that can perform the process of exchanging data. And also captures WiFi signals, which this WiFi adapter can strengthen the capture of existing WiFi signals.
Short Definition of Wifi Receiver
WiFi adapters are often referred to as WLAN Cards. A WiFi adapter is a device used on a computer or laptop device that can be connected to a WiFi connection that is available in ad hoc mode.
In infrastructure mode, the data will be transmitted using the access point as the center. All existing connections will be named with the service set identifier or WiFi SSID as the access point.
It also includes using a security code such as WEP or WPA according to the settings. Meanwhile, in ad-hoc mode, the network connection does not require an access point and is directly connected to all wireless devices. In this type of connectivity mode, ad-hoc mode connections need to use the same channel and SSID.
Wifi Adapter Function
The function for the WiFi adapter itself is to receive and spread the WiFi connection signal from one computer to another.
WiFi adapters can be used to switch connections between PCs and other devices easily and quickly.
With this wifi adapter, we can open to a wifi hotspot network around our house or if we want to share files on another PC or laptop via a wifi network can be done with this device.
So from that, this wifi adapter has a very necessary and ‘must’ function to be embedded in electronic devices such as PCs or laptops.
Outdoor Wifi Antenna
Now this time we will discuss an outdoor WiFi antenna which can provide a wide range of WiFi signal needs suitable for placing outdoors or outdoors.
The need for an internet connection will certainly be needed by every individual anywhere and anytime, including outdoors, especially in a corporate environment.
In addition to the existence of a router which is very much needed by internet users, it is also necessary to have a device called an antenna grid.
Short definition of outdoor wifi antenna
The definition of an outdoor WiFi antenna or grid antenna is WiFi that serves to amplify and direct WiFi signals to make point-to-point, or multi-point connections.
This antenna also receives and sends data signals with a 2.4 Mhz radio wave system both intranet and internet.
Outdoor wifi antenna function
The function of the outdoor WiFi antenna is to operate by receiving data signals and sending data with 2.4 Mhz radio waves.
After the internet or intranet data will be sent and captured by the device in order to access the internet. However, there are some WiFi signals that use WiFi passwords so that they can add to the security side.
How Outdoor Wifi Antenna Works
This outdoor WiFi antenna or commonly referred to as a grid antenna operates by receiving signals or data radio waves and then transmits them using a 2.4 Mhz radio frequency.
Grid antenna will operate by receiving a data signal and then sending it with a 2.4 Mhz radio wave system.
The date can be intranet or internet. After the data is sent, your device will catch the signal and you can open the internet. This Wi-Fi signal is available which is locked by a password but is also available which is not.
WiFi Transmitter Antenna Type
The shape of the WiFi antenna itself varies with the design, frequency, and gain distribution pattern.
Because the antenna itself is the most important part of a transmitter or receiver with a function as a signal spreader. So we need to know the difference between the types of WiFi antennas that you will buy later.
The following is some information about long-range WiFi antennas with different types and their respective functions:
Grid antenna is a kind of outdoor WiFi antenna with long range WiFi technology. With this antenna beam pattern, it focuses more on one particular point in its installation. For the coverage itself, the network antenna coverage is a straight line which has two frequencies, 2.4 GHz and 5.8 GHz.
Omni / Omnidirectional Antenna
The omni antenna has a stick-like shape with a fairly small size. This antenna has a broad signal beam compared to GRID where the signal coverage spreads in all directions and forms a circle.
This antenna is also in fact very suitable for use as P2MP (point to multipoint) in wireless networks, and also very suitable for access points.
In addition, this antenna is also used for large areas but short distances. Since the Omni’s antenna covers a large area, it is highly likely that other unwanted signals are also being collected. Therefore, the omni antenna will invite interference.
The sectoral antenna has almost the same function as an omni antenna which is used for access points that serve P2MP point to multipoint.
However, sector antennas have almost 2x the gain which is further than omni, which is up to a range of 6-8 km.
The beam angle of this sectoral antenna ranges from 45 to 180 degrees with maximum mounting.
In the installation of sectoral antennas there are two types, horizontal and vertical beam patterns. In this antenna, the transmit signal especially in the direction that the antenna is directed matches the beam range, but there is no emission signal at the rear of the antenna.
This type of sector antenna, if installed above, will be much more profitable because it is able to receive a good signal in a sector or region. This sector antenna itself is actually usually used in GSM towers
Yagi antenna is a type of network antenna, this antenna has a unidirectional range which has the main difference between yagi antennas and GRID antennas in that they are rarely used on a network.
The antenna also consists of 3 parts, namely the mover, reflector, and director. While Powered is the antenna cable supply point.
The physically managed length is usually half the wavelength of the radio frequency that is either received or transmitted.
The reflector is located on the back of the antenna that is used for you to reflect the signal while the physical length of the reflector will usually be longer than the one that is driven.
The physically managed length is generally one-half the wavelength of the received or transmitted radio frequency. The reflector is the back of the antenna that is used for you to reflect the signal. The physical length of the reflector will usually be longer than the driven one. While the director is the direction of the antenna. This section is shorter than a driven.
This antenna is indeed made of PVC pipe covered with aluminum foil. This antenna is indeed a development of canned antennas that are installed outdoors or often undergo oxidation.
This WiFi antenna also has a very short signal range, which is between 200 – 300 m.
8 Quad antennas
The 8 quad antenna is a type of sector antenna. Where this antenna has a signal transmission pattern in one direction with a directional angle. This 8 quad antenna is usually used in cases installed in areas that have a lot of users.
Bolic Wok Antenna
In 2005 this antenna was named Bolic Griddle which is similar to a satellite dish. This antenna is quite simple with ingredients made from kitchen tools such as pots or pans used for frying.
The bolic grid antenna is used to amplify the wireless signal from the access point because it is too far away or difficult to receive by the USB wireless adapter if it only opens directly to a PC or laptop.
Parabolic antennas, usually these antennas are often used by cable TV service providers which are similar to grid antennas, but have a better range and signal focus that is farther away than grid antennas.
Make a WIFI antenna from simple equipment.
In making your own outdoor WiFi antenna, you can also make it from simple items and equipment, which you can get at an electrical shop, except for the connectors or cables.
You can make a WiFi antenna with an omni directional modem as an antenna that can radiate in all directions.
The omni directional antenna function provides a WiFi or internet signal that can be enjoyed by those around you. So that the area around the house also receives internet signals from the WiFi modem, or it can also be reached to the home area so that nearby users can catch the signal.
The process in making a simple omni directional WiFi antenna that can be placed on the roof of the house or the front of the house to make the WiFi antenna as an outdoor antenna.
Connecting components for Outdoor antennas use the order
For example, we take for example 6dBi and 8dBih a WiFi router with the brand TP-Link TD WA8951ND which has 1 antenna. The antenna connector can later be removed and replaced with an external outdoor antenna.
You can use a cable to connect the wireless router. Which uses the TP-Link TL-ANT24PT3 cable as a connecting cable from the wireless router to the outdoor antenna
DIY WIFI antenna design
First you need to use 2 simple WiFi antenna designs that you can make yourself. Omni directional antenna with 6dBi and 8Dbi power.
For 6dBi has a length of about 23.5cm, while 8dBi has a length of about 51cm. as for you can use the omni directional antenna below which requires one M-female connector as the antenna base.
For the antenna pole, you can use a copper cable from the power cable. Every curve
The design of the Omni Directional antenna is below. It only requires one M-Female connector as the antenna base. While the antenna mast uses copper wires from the power cable. Each indentation of the line on the antenna is a loop made circular with a diameter of 15mm or according to the size of the tube used.
Below is a chart or picture of two different diagrams to trigger the Omni Directional WIFI antenna of 6dBi and 8dBi strength.
Components of making their own WIFI antenna that are not available in the market are the M-Female connector. Generally sold in specialty stores that sell antenna equipment, and amateur radio equipment. Or you can expect protection from jogjabolic.com which sells WIFI / Networking equipment and components.
For components that need to be prepared in making the WiFi antenna itself is a thin tube to coat the copper components. In packaging the antenna mast is assembled later which is purchased at an electrical store or used second hand. You can use a plastic tube to cover the antenna with thin walls.
- Copper wires from electrical wires. Can use not thin 2mm copper.
- Epoxy, or PVC glue if the antenna wants to be permanently closed.
- Electrical insulating tubes are generally sold in electrical stores.
- Soldering tools, pliers, electronic lead for connecting connectors to copper wires.
- Antenna cable for connecting external antenna with wireless router
How to Choose An Antenna to Amplify Internet Signals and Networks
There are many types of outdoor WiFi antennas on the market and also brands that offer various advantages.
But you are confused about choosing which antenna is suitable for your needs, in this case we will discuss how to choose an antenna that can strengthen the internet signal.
The price of outdoor WiFi antennas in the market can be found quite cheaply. But sometimes the price describes the quality of the outdoor WiFi antenna. Placing the appropriate modem for outdoor WiFi in order to capture the internet signal optimally.
Adjust default speed with connection
Each outdoor WiFi antenna has its own speed or capacity. Things that are adjusted to the performance of the antenna or repeater will not be able to compete with the main modem considering their function is only as a support.
So before buying it would be nice you can find out the maximum speed of the modem, especially if you want to buy it online.
Choose an antenna with dual-band simultaneous connection
For how the dual-band antenna works, it is a type of modem that can pick up the signal and transmit the main modem from one band to the other side. Band one is usually able to break through barriers, while the second tends to be weak.
For how to choose a modem antenna, the speed of the main outdoor WiFi antenna through the signal beam to the two bands of the device.
Consider the shape of the antenna used
For the model of the antenna there are actually 2 types of models that are often used. Among other things, plug-in models that you need to connect to an outlet and stationary models in other words portable that can be placed anywhere.
The choice of antenna shape can be affected where you install the main modem. The condition of the house also has an impact on the placement of the antenna. For example, a plug-in antenna that hangs from a wall outlet so that it can be useful to assist the main modem.
Look for an antenna with a WPS button
To choose an outdoor WiFi antenna, look for a device that has a WPS or WiFi protected setup feature. WPS is a security process that allows you to adjust the mode on the antenna for the first time, so that it will be easier for you to use it.
If WiFi is not equipped with WPS you can still use the antenna, but the settings will be done manually, so it’s a bit difficult at first.
Antenna Performance Characteristics and Parameters
Outdoor WiFi antenna in supporting its performance, you need to pay attention to its characteristics. The characteristics or parameters of this WiFi performance are at the time of making the antenna or when selecting the type of antenna needed.
The four parameters or characteristics of the antenna are as follows:
Directivity gain is an antenna parameter that measures the antenna’s ability to direct the signal wave in a certain direction. Or it can also be said that this gain measures the efficiency of an antenna. This gain can be measured in decibels.
Directivity is a comparison with the power density of the antenna at a certain distance of a point relative to an isotropic radiator. What is meant by an isotropic radiator is a signal transmitter in all directions.
Polarization or Polarization is the direction of propagation of the electric field. The polarization of the antenna in question is the electric field of the radio waves connected to the earth’s surface and the compatibility of the physical structure of the antenna with its orientation.
In polarization recognition it is useful to get the maximum efficiency of signal transmission.
Antenna Radiation Pattern
Antenna radiation pattern is a radiation depiction of the strength of radio waves propagated by the antenna at the level of reception of the signal received by the antenna at different angles.
In general, this radiation pattern is described in the form of a 3-dimensional plot. The radiation pattern of this 3-dimensional antenna is formed by two radiation patterns, namely the elevation pattern and the azimuth pattern. The radiation pattern is an omnidirectional pattern, which is a radiation pattern that is uniform in one radiation field and a directive pattern that forms a narrow beam of light with high radiation.
That’s our discussion of Netdata this time about outdoor WiFi antennas, starting from the meaning of WiFi, the benefits of WiFi, as well as several other WiFi explanations such as WiFi prices, WiFi SSID, WiFi express, WiFi tents, WiFi passwords, WiFi receivers that need to be explained to increase understanding. of the outdoor WiFi antenna technology itself. Hopefully useful from this article and thank you.
