Are drone jammers directional or omnidirectional?

Are drone jammers directional or omnidirectional?

  • 2022-09-02

Some customers have been very entangled in the selection of antennas when selecting drone jammers, and they have never been able to make up their minds on whether to choose a directional antenna or an omnidirectional antenna. So, are drone jammers directional or omnidirectional?

It is not difficult to figure out this problem, because directional antennas and omnidirectional antennas each have their own advantages and disadvantages. From a conventional comparison point of view, the directional antenna has a larger appearance size, but the gain value of signal transmission is relatively high, and the transmission distance in the direction of its main lobe will be significantly larger than that of the omnidirectional antenna. The appearance of the omnidirectional antenna is relatively simple, usually in the shape of a round tube, and the gain value is usually only half or even lower than that of the omnidirectional antenna. But the advantage of the omnidirectional antenna is that it allows the jamming signal of the drone jammer to be emitted omnidirectionally around, so it has a wider coverage.

As for how the omnidirectional antenna and directional antenna are finally determined, our suggestion is based on the actual use needs of customers. For example, at the site used by the customer, the drone jammer needs to be turned on for a long time and used continuously, and the target range is also very wide. When indiscriminately jamming or driving away the drones that may invade around, you can Choose an omnidirectional antenna without hesitation. However, if the customer is using the site, because they are worried that it will affect the daily life of the surrounding people, and at the same time need to reasonably avoid some areas to avoid interference, then in this case, it is definitely recommended to select the orientation for the drone jammer. antenna up. This minimizes unnecessary disturbed areas. Moreover, it can also strengthen the key interference of the incoming direction of the invading drone.
