How To Build A Long-Range Wi-Fi Antenna?

Dish antennas are generally used for long-range signals because of their quality that they transmit and receive long-range signals. These antennas are used for satellite communications and dish TV. Its structure is very simple; it has a curved metallic surface which is attached to a receiving unit.

The rays are caught by the curved metallic surface of the antenna and refracted to an angle where the receiving unit captures them. The receiving unit then converts these electrical signals into amplified signals through the internal circuit.

Components Of Wi-Fi Antenna

To build a homemade Wi-Fi antenna, it is necessary that the elements are arranged properly to obtain the exact result. There are three main components of a homemade Wi-Fi antenna Wi-Fi source on a module, a cable, and an antenna.

First of all, we need to focus on the antenna element to catch the Wi-Fi signal properly. Extensively there are two types of element antenna. These are directional and omnidirectional. There are some properties associated with both to help you figure out which connection do you need exactly.

A directional Wi-Fi antenna radiates a signal in the form of a beam pattern which can be directed in a specific direction and covers a long distance. If the location is known, it will work the best.

In an Omnidirectional antenna, the First source is a constantly changing position with reference to the receiving element. It generates a dispersive 360-degree coverage and suits best if you are connecting it with indoor devices.

The second thing is the Wi-Fi cable that would connect the Wi-Fi module and external antenna element for Wi-Fi. These cables play a significant role in catching the signal effectively, so it is better to use a cable. This cable needs to be connected to your device like a computer or laptop for better working. They ensure a smooth signal flow between the Wi-Fi antenna source and the connected device.

The last and most important component is the Wi-Fi module. It is the device that receives the signals.

Step By Step Process Of Making A Wi-Fi Antenna

  • First of all, expose the internal PCB by opening up the USB Wi-Fi module.
  • Now you need to find the IP terminator, which is at the end of the PCB in a USB connector.
  • In the third step, you need to attach the lPX connector to the USB to create a Wi-Fi antenna.
  • The fourth step is to create a link ok for the cable assembly through the USB wireless adaptor full stop for this purpose, make a small hole in the wireless adaptor USB and then pass the SMS to the IPS cable close to the place where the cable connects with the PCB board.
  • The final step is the reopening of the USB wireless module to insert the PCB receiver module into it, then allowed the cable to pass through the newly made hole and then close the housing USB.

Method 2:

There is another method that you can adopt to make a long-range Wi-Fi antenna. Follow these simple steps to get your work done in no time.

  • The first step is cleaning your dish antenna thoroughly and removing all the dust using a sandpaper. The cleaning is essential for the proper reflection of EM waves.
  • The next step is to remove the receiving unit, which is also called the feed horn, from the dish.
  • The third step is the placement of the Wi-Fi adapter. Its direction should be kept in mind that the receiving antenna off the Wi-Fi adaptor is precisely near to the focal point of the dish.
  • The fourth and final step is to direct your antenna towards the direction in which you want to transmit or receive the Wi-Fi signals. This process needs to be done very carefully using mathematical calculations. It is not easy as it seems to be.

Measurements While Installing A Wi-Fi Antenna

There are two kinds of measurements that would determine what type of antenna, whether directional or omnidirectional, you would use. These are called dB and dBi measurements.

dB measurements show the signal gain. It depends that how many intense signals can be gained from an antenna. It is pretty interesting to know that the higher the dB, the signal measurement is excellent. The higher the dB is, the better your signal strength would be.

Measurements While Installing A Wi-Fi Antenna

dBi measurements show the signal and distance of the antenna. As the dBi increases, the coverage of the antenna decreases. It shows an inverse relationship between signal strength and antenna.

So, the indoor and outdoor antennas differ with respect to their dB and dBi values, respectively. A parabolic antenna is directional; it only ranges 10 miles, but there are certain conditions required for it. If any of these conditions are missing, its range would be decreased ultimately.

The outdoor antenna, on the other hand, has a greater value and gives a more extensive coverage in 360 direction, but the range is different. It is approximately 4 to 5 miles.

What Is The Need For Making A Long-Range Wi-Fi Antenna?

In order to connect to the Wi-Fi and establishing a connection to a network, it is necessary that you are within the range of the Wi-Fi and probably most closest to them. So external point to point networks is made through high antennas to extend the range of wireless signals effortlessly.

Another need for the outdoor Wi-Fi connection is that indoor connections are distorted by the presence of obstacles in their way like walls, buildings, windows, and doors, etc. So, external Wi-Fi connections are better as there are no obstacles in their way, so they are less distorted. But if the distance is increased between the Wi-Fi transmitter source and the receiver, the signal strength automatically decreases.

If to share the Wi-Fi source with a neighbor building or your house is big, then you can use a long-range point to point network. In these networks, the Wi-Fi source ranges signals from a few feet to a few miles away from it. Point to point long-range signals are better because the patches of signals together create a larger network of internet accessibility.

 Long-range point to point signals are used with the Wi-Fi routers inside a closed building. They retain the signal strength within the building premises. The routers and Wi-Fi devices vary in their signal strength and range.

 So, if you have a large building to supply with the internet connection, then and you can choose our larger router having more signal transmitting strength, or you can use small router networks placed at minimum distances so that they form a large nitrile and cover the whole area effectively.


So, there are two basic methods to make wireless antennas as both internal and external networks. For an internal network, you can create the USB network antenna by following the first method. For an external network, you can use a second method using a dish antenna.

The factors such as distance, signal strength, and mode of connection, whether indoor or outdoor, suggest the type of antenna that you should use. Making your own Wi-Fi antenna is the best option instead of finding a network router which is much costly.
