Buying Guide for the Best High Gain Antennas for WiFi Routers

Before you buy and install your high-gain antenna, there are numerous factors that you will need to keep in mind and under consideration. High-gain antennas aren’t created equal, and this means that you need to look at all the features and the functions of the antenna before you buy it in a bid to make sure that the antenna offers the best-desired benefits.

As the high-gain antennas are designed to increase the broadcast range for your WiFi router and others even capable of increasing your home’s WiFi speeds, you need to ensure that you have the right antenna for your router. Other antennas will also work by enhancing your broadcast control, specifically the omnidirectional antenna rather than the directional antenna, which will result in a higher level of precision over the direction of the signals broadcasted. With all these possibilities in mind, you need to make sure that you have the best of the high-gain antennas. To bring this dream into reality, you need to know the basics of the high-gain antennas, as well as the things that make some of these antennas better than others.

Types of High-Gain Antennas

There are two types of high-gain antennas for the wireless routers: the omnidirectional and the directional antennas.

The omnidirectional antennas work by broadcasting the radio frequency in all directions by creating a sphere of wireless coverage. On the other hand, the directional antennas are designed to focus radio signals/ frequencies in only specific directions, hence the creation of a larger coverage and distance.

There also are specialized high-gain antennas such as the Yagi and the parabolic antennas, which have the potential of broadcasting wireless signals for large distances over miles. Obviously, you don’t need that much coverage, but if you need a significantly larger coverage, then you might want to opt for the smaller designs of the parabolic antennas.


Note that the ‘gain’ in high-gain antennas refers to a meter of the sensitivity of the WiFi antenna. With a high level of sensitivity of the antenna’s gain, it means that the antenna will be able to receive the long-distance WiFi waves better.

The gain is measured in dBi or decibels, and the decibels of gain refer to the algorithmic relationship between the antenna’s emission power, the intensity of the emitted radiation, and the directivity of your antenna. But these aren’t the only factors that will affect the gain of the antenna because the gain is highly influenced by the shape and the size of the antenna.

In this case, the large, flat antennas are designed to receive more of the signals that are further away from the router. In the case of extreme connections that cover kilometers, you will find that the commonly used high-gain antennas are the large parabolic antennas (these are about 1meter in diameter).

Radio Bands

To choose one type of high-gain antenna over the other, you need to bear in mind important questions and factors like the design of the high-gain antenna and your router’s operating frequency.

Generally, the WiFi broadcasts on the 2.4GHz and the 5GHz bands, with the 2.4GHz being the slower frequency range and the 5GHz band as the faster frequency. But that is not all that you need to know, and within the broad bands, there are broadcast channels. Often, most routers will pick the broadcast channel automatically, but others use their default specifications. In other cases, the routers are designed to assign the channels that have the least possible interference thanks to the use of the ‘smart analysis’ technology.

Router Placement

When it comes to the search for the best high-gain antennas, you need to always keep in mind the placement of the router because it will play a vital role in the router’s broadcast range. If you have your router placed too far off the corner of your living room might not be the best idea if you want the router to broadcast signals to your backyard, especially if your backyard is on the other side of the house. For the best range throughout your home, consider placing the router at the center of your home, and away from solid restrictions and walls.

Wireless Standards

You need to consider the router’s WiFi standard because WiFi is not WiFi. There are different WiFi standards in the WiFi world, and they all govern your router’s broadcast frequency and range. The mainstream wireless standard 802.11ac, for example, will broadcast wireless signals in the 5GHz band to distances around 100 or 150feet at high speed of up to 1Gbps – but this will only happen on the 5GHz band. On the other hand, you have the longer-range 2.4GHz band that broadcasts WiFi signals at speeds of 300Mbs over longer distances between 200 and 250ft. What this all means, in a nutshell, is that you need all your router/ network devices running on the same wireless standard for the broadcast signals to reach as far as you’d want them to.

Broadcast channels

Before buying/ installing your high-gain antenna, you need to bear in mind that your router will broadcast WiFi signals on specific channels, often the default channels. Make sure that the antennas are designed to broadcast on that channel too.

Integrated power boost

The other important consideration that you need to keep in mind is the router’s power boost function. This might increase the range and performance of the router’s WiFi signals, especially with the antennas in play. So, makes sure that the power boost is on before you install the antennas.

  • Distance

Besides the size of the antenna, the coverage of WiFi signals is often affected by distance, and this means that you must keep in mind the distance when buying an antenna.

Essentially, you’ll need a USB WiFi adapter that comes with a simpler Omni-directional antenna is you need to improve wireless coverage in smaller spaces. However, you will need bigger antennas for larger areas, especially if there is a lot of interference for you to deal with.


There also are high-power antennas, but before you buy a high-power antenna, you will need to bear in mind that the WiFi’s power is measured in mW or in dBm, and for the use of the most powerful antennas, your router must also have a powerful antenna.


What is a high-gain antenna?

A high-gain antenna or an HGA refers to an antenna that features a narrow radio beam that increases WiFi signal strength. These antennas offer a more precise option for targeting radio signals, and it is essential in long-range networks where they can be used to amplify the weak signals in satellite communications.

Do I really need the high gain antennas?

Before you invest in antennas for your WiFi router, you first need to know that the antenna will not make any power for the wireless signals, and all it will do is to propagate the radio waves. Also, the antennas will propagate the signals in different patterns – Unity Gain, ¼ wave antennas, are designed to propagate the signals in a circular/ omnidirectional pattern. In the case of a high-gain antenna, increasing the fain in one direction will result in decreased propagation in the other direction, which means that the high-gain antennas will result in the loss of the roundness or the vertical propagation of the signal pattern, where they will be more elongated and flattened in part with the higher-gain. Therefore, you should only get these high-gain antennas if you want the wireless signals to be more focused on one area and not the other.

Is the high-gain antenna beneficial?

Well, it depends. You only get to enjoy the full benefits of the high-gain antenna is you know exactly where you wish to enjoy the directional signals (the area where you’d like to have the maximum gain). But if you don’t know the direction that the desired signals will be coming from, then it will be better to have the low-gain antennas.


The high-gain antennas above are some of the best antennas on the market, and they offer excellent performance. To choose the best antenna option for you, all you need to do is to consider your needs.
