Omnidirectional antenna buying guide

The omnidirectional antenna is one of many types of antennas that can receive television signals or radio broadcasts. As the name suggests, it is used to send and receive different types of signals, which can come from any direction. The omnidirectional antenna is typically used to pick up a long range signal, without having to use cables or wires. To help you understand the usefulness of the omnidirectional antenna, and help you choose the model that best suits your needs, take a look at our comparison.

The difference between an omnidirectional and directional antenna

The omnidirectional antenna is also called a vertical antenna or a stick antenna. It is generally used in a WiFi internet connection system, that is to say wireless. This is because the omnidirectional antenna emits a 360 ° radius around it and enables it to pick up a strong signal and extend it from an access point.

The omnidirectional antenna can be found on all wireless devices. It is originally connected to an rp-sma connector offering a gain between 2 and 4 decibels. Depending on your choice, you can further increase this gain up to 9 to 15 decibels for optimal results. Just replace the indoor antenna with a coaxial cable, which will be connected to an omnidirectional antenna and place it on the roof of your home.

In contrast, the directional antenna has the advantage of concentrating the signal in a given direction. It can also extend this signal over several meters, or even kilometers. Its operation is ideal for forwarding the signal from a router (in the case of a wifi connection) to any location.

And there are also the sector antennas, which are a performance mix between the omnidirectional antenna and the directional antenna. Indeed, the sectorial antenna can offer an opening of up to 180 °. With the characteristics of a directional antenna, this is just ideal for properly broadcasting a signal.  

These types of antennas can be used both in the Wi-Fi connection system and in the reception of satellite images for television or radio broadcasts. They are also perfectly recommended to allow you to capture beautiful images in a motorhome. Many who have taken the test claim that a better omnidirectional antenna is much more satisfying on a motorhome than any other model.

How to choose your antenna?

It is always necessary to start from a detailed comparison to be able to choose the best antenna adapted to your needs. Indeed, it is important to be based on various criteria such as the location and distance of the transmitter, the frequency bands, the type of antenna (indoor or outdoor), etc. These factors are important in ensuring the quality and strength of the signal your antenna will transmit.

According to the opinions of users who have already tested several types of antennas, consider the fact that there are indoor and outdoor antennas.According to them, indoor antennas are unfortunately less efficient than outdoor antennas.Indeed, to function properly, they must be placed near a transmitter.The path between them and the latter must not be strewn with obstacles to ensure the quality of signal reception.That is to say, this distance should not be disturbed by buildings, mountains, hills, etc.On the other hand, the outdoor antennas are more satisfactory.They have the advantage of picking up a signal from a long distance.However, their performance will also depend on their design technology.

Both types of antennas, indoor and outdoor, can be equipped with a signal booster for optimum efficiency.

What criteria should be taken into account when choosing an omnidirectional antenna?

Whether you choose a directional antenna or an omnidirectional antenna, there are a few technical and specific criteria that should be taken into account. These ensure in particular a clean and powerful signal, which gives you good sound and picture quality.

Among these selection criteria, you have the frequency bands and the types of antennas.The frequency bands can be VHF or Very High Frequency which literally means "Very high frequency".This type of frequency band can generally cover between 30 to 300 Mhz.There is also the UHF or Ultra High Frequency or "Ultra High Frequency" band which is a better and wider bandwidth.Generally, the UHF can receive all the offers of television programs on a given geographical area.You can also find dual frequency antennas (UHF-VHF combination).They have the advantage of adapting to all circumstances to give you the best signal.

As the type of antennas, you have the rake antenna, the panel antenna, and the satellite dish. In the case of a satellite dish, it is essential to find the orientation correctly using a compass.

The best omnidirectional antenna that will suit your needs will then depend on all of these criteria. In order to guarantee your satisfaction and a profitable investment, do not forget to take this comparison with you to establish the best choice.
