How to choose your omnidirectional antenna

In order not to regret your purchase of an omnidirectional antenna, we invite you to take into account the following criteria.

#1 - The frequency band

The frequency determines the quality of the antenna as its coverage and signal quality depend on it. The frequency of an antenna depends on its bandwidth. In turn, the frequency will define the size of the antenna. The omnidirectional antenna, in particular, is characterized by a frequency ranging from 700 to 2700 MHz. Keep in mind, however, that the lower the frequency, the greater the range.

#2 - The cover


achieve reliable coverage, it is best to place the omnidirectional antenna in the center of the area of interest, taking into account the antenna's polarization and pattern. The low gain omni-directional antenna provides wide vertical coverage, and the higher gain antenna focuses on flat but more intense coverage. The omnidirectional antenna should not be placed at too high a height to ensure a good signal to those in the near ground area.

#3 - The length of the cable


criterion an important role insofar as the antenna is not attached to your TV or other device. In fact, the cable is used to place the antenna in the best location for the best signal. If you need additional cable, choose a large, less flexible cable, which will reduce losses during transmission. Otherwise, you can also choose a Teflon cable of the length you need.

#4 - The installation


types of attachments are possible depending on your needs. If you intend to connect the antenna directly to your device, the screw system is the most suitable. Magnetic mounting allows you to connect the antenna to any metal surface. For better security and to favour a high installation, the antenna can also be fixed on a mast, inside or outside. If the installation surface is smooth, you can choose the adhesive mounting option.

#5 - The gain


in DBi, the gain of the omnidirectional antenna is determined by several elements: shape, dimensions, installation quality, age, etc. Among other things, the larger the antenna, the higher the gain. A low gain omni-directional antenna is still ideal for indoor coverage. Regardless of the amount of obstructions, the omni-directional antenna provides a suitable signal quality indoors.

Omnidirectional antenna and motorhome

The motorhome is attracting more and more people and now, thanks to the omni-directional antenna, motorhome enthusiasts cannot do without TV. How to use it properly? What are the points to know? The answers in these few lines.

Very easy to install, the omnidirectional antenna is perfectly adapted to motorhomes or caravans. Thanks to it, the signal received remains of high quality because it receives it on 360°, for a broadcast of images that does not risk to be altered on the whole journey. Place your omni-directional antenna on the most suitable corner of the roof of your vehicle and fix it on the support of your choice.

When purchasing an omni-directional antenna for your motorhome, pay special attention to the connection means, especially the cable. In order to avoid frequent signal loss, choose double or triple shielded wires, which are considered to be of better quality. Check their age and if necessary, do not hesitate to renew them to keep a strong signal. There is no need to remind the compatibility of the omnidirectional antenna with your TV, it should be part of your first reflexes.

Finally, depending on the size of your vehicle and the distance between the omnidirectional antenna and your TV, pay attention to the length of the cable you will use. This criterion will unerringly determine the quality of the signal you will receive. The longer the cable, the easier it will be to install and find the right location

Omnidirectional or directional antenna?

Omnidirectional antenna

This type of antenna transmits and receives signals of the same strength in all directions of a defined plane. This signal strength thus varies as you move through an area corresponding to the perpendicularity of the plane. In other words, the signal receivers are not in fixed locations. Telephony or FM radio signals are examples of contexts that require the use of an omnidirectional antenna, since the signal is not received at point locations.

Directional antenna

The directional antenna, also known as a directional antenna, receives and transmits signals in a single predefined direction. The system consists of placing the transmitter of the signal and the receiver that broadcasts it face to face in order to retransmit it as clearly as possible to devices such as the TV. A typical example of a directional antenna is the parabolic antenna, which is responsible for the broadcasting of many international channels via satellite.


The omni-directional antenna is an interesting alternative if you are frequently on the move and don't want to miss your usual TV programmes. The directional antenna, on the other hand, is fixed at a precise location in the direction of the satellite to transmit all your international programs.


The importance of "low loss" cable

When purchasing, make sure you have chosen a model with a low-loss cable to avoid any signal degradation. As for its length, you will determine the one you need according to it.

Use good connectors


performance of connectors lies in their materials, make the right choice! Favour gold-plated connectors or connectors with a special alloy plating, silver for example, these will guarantee you a better signal quality.

The right height


installing your omnidirectional antenna, prefer a location at the highest height. This will ensure that you get the best gain.

Don't forget the accessories!


make sure you get your hands on the right model of omnidirectional antenna, still check that it has all the necessary accessories: amplifier, cable, mounting systems, etc


The divider option


enjoy a better entertaining experience on your long drives, prefer a model equipped with a splitter that allows the connection of another device of your choice: TV or radio



What is the best omnidirectional antenna?

The best omnidirectional antenna depends on your needs and budget. Read our buying guide to find the best products available.

How do I know if the reception is good?

As soon as it is installed, you can check whether the quality of the signal received and transmitted by your omnidirectional antenna is good or not. To do this, simply enter the device's parameters and check the RSRP or Reference Signal Receive Power value. The lower this value is, the better the signal quality will be.

Is it necessary to use a demodulator?

During installation, the use of a demodulator is not necessary. You just need to make sure that your antenna is not far from the transmitter.

What is the difference between an isotropic antenna and an omnidirectional antenna?

The isotropic antenna emits equal power in all directions, while the omnidirectional antenna emits equal power only on areas perpendicular to the position axis.

How to improve the gain of an omnidirectional antenna?

To improve the gain of an omnidirectional antenna, you can decrease the height of its main lobe, and thus limit the radiation towards the clouds.
