Multi Directional vs Omnidirectional Antenna

Updated On July 5, 2021

These days, a lot of people want to know the difference between omnidirectional and multidirectional antennas. Even here it is necessary to mention the so-called directional antennas.

Each of these antennas may be needed to receive different types of signals. However, any of these options cannot provide the same performance in any geographic location.

Here, you may check the best omnidirectional TV antenna in the market nowadays!

Directional Antenna

As we have mentioned, directional antennas are mostly used for certain specific functionality. In this case, it is an antenna that can be found in a large number of homes. Here, in turn, it is possible to have a much stronger signal compared to a multidirectional antenna.

Thus, this type of antenna is directed to stations and shelves as television transmitters. This is why these antennas are used and work much better with the weaker signals. To change their orientation or their target, other accessories can be implemented. A good way to complement this functionality is with a rotator. This will make it much easier to change the directionality of the antenna.

So if you want to get an excellent experience from a single signal, then a directional antenna is best. Even this can be efficient when there are cell phone towers but they are too far away from your location.

Increased amplification: Here the main benefit is that the experience can be optimized by receiving a weak signal. In turn, the directivity gain is much more convenient and allows the user to enjoy much more than with a multi-directional antenna. 

Less interference: Here it is necessary to consider that this type of antenna can be directed towards a certain signal. In this way, it is possible to suppress unwanted signals or interference.

Besides, the gain that can be obtained from other secondary signals is significantly reduced. This interferes/signal ratio more than balanced and convenient for the user.

Stability in signal reception: Here because the level of interference decreases considerably is that the level of stability increases. So, for this to happen, the target base station tower should not be faulty or congested.

In case of malfunction, the user should align the antenna to improve the result. In conclusion, in more remote locations where there is a very low number of signals, it is better to have a directional antenna. 


Complicated installation: First of all, it is necessary to consider that this type of antenna cannot be installed just anywhere. Instead, it is necessary to find the most appropriate site as the antenna will be directed towards a particular target. Otherwise, then the result might not be suitable when the antenna is misplaced.

Potential failures: As mentioned, the results here can be negative when the cellular base station or tower is faulty and congested. Compared to an omnidirectional antenna, the impact here will be much more severe and considerable. So to overcome this disadvantage more efficiently, an omnidirectional antenna would be better. 

Omnidirectional Antenna

What is an omnidirectional antenna? In this case, omnidirectional antennas are also often called multidirectional antennas. This type of antenna can receive signals from a large number of directions.

It is necessary to consider that these units cannot have the ability to focus on a specific transmitter.

Therefore, the signal they can receive has a lower intensity concerning the directional antennas. In combination, this type of antenna is an excellent choice depending on the area in which the person lives.

Here it is advisable to install an antenna with strong signals and TV transmitters not too far away. In this way, it will be much easier to obtain excellent functionality.

Excellent signal reception: As we have mentioned, one of the main benefits that can be obtained in this case is the ability to receive signals from all directions. So an LTE-enabled router can provide efficient routing. Here we will notice that it is an excellent option for several multidirectional cellular mobile base stations. (1)

Better performance in case of failure: In this case, it is necessary to mention that the possibility of receiving signals from all directions is another advantage.

Here it is possible to receive another signal in case a cellular base station or tower cannot offer good performance. Even this can happen when the tower is too congested and cannot offer a higher capacity.

Simple installation: This type of antenna has an excellent level of advantages such as easy use and fast installation. So this can offer an excellent time-saving advantage. However, there are still other advantages to be mentioned.

Quick setup: Additionally, it is also often the case that when the network changes, then an adjustment or realignment may be required. This is especially not the case with the omnidirectional antenna due to its high level of functionality. In turn, network changes could also mean some specific problems, or simply new sites and locations.


Relatively minor overall gain: It is necessary to consider that the maximum performance that can be obtained in an omnidirectional antenna is lower than other options.

Thus, since this antenna covers many signals then the maximum functionality cannot be achieved in each case. On the other hand, directional antennas are more functional for maximum performance.

A greater amount of interference: One of the major disadvantages is that an omnidirectional antenna will have to overcome a large amount of interference. In particular, this simply happens because the signals received come from all directions.

Of course, this also decreases the strength of each received signal. Even the ability to receive a large number of signals could quickly become a disadvantage. This depends exactly on the geographical area in which a certain person lives.


1. How does a directional antenna work?

In particular, these types of antennas are directed at a specific signal, such as a television broadcast station. It is possible to reduce the amount of interference that other signals can produce. In turn, this type of antenna is more suitable for weak signals.

2. Is the Wi-Fi antenna directional?

Wi-Fi antennas can provide one-way functionality. Here the entire frequency pattern is transmitted and received from the wi-fi signal forward. Here, the angle can be narrower or more open depending on the type of wi-fi antenna. (2)

3. How far will a Wi-Fi antenna reach?

All wi-fi antennas have a certain limit of the range in their operation. An intermediate quality signal can reach up to 304.8 meters without any obstructions. On the contrary, in a closed area and obstructions, the maximum range is 91.44 meters.


Without a doubt, knowing the difference between the two most used antennas in these times is important. This way, you will be able to choose the best compliment for your home. So, if you live in an area without too many signals then it is more convenient to choose a directional antenna.

In contrast, in large cities, it is more convenient to choose an omnidirectional or multidirectional antenna. In this case, we are talking about the same antenna and will have the ability to receive a large number of signals. Even since the signals are stronger, then the experience will be optimal.

We hope this guide helps you with choosing what's best for you and your home location.
