drone jammer

The drone jamming gun can now be seen in many security occasions. Its main function is to interfere, make a forced landing or run away from an illegally used drone after it is discovered. Most drone jamming guns use directional antennas to transmit jamming signals. Then, for drone jamming guns produced by different manufacturers, the types of directional antennas selected will be different. What about directional antennas?

The early manufacturers of drone jamming guns generally choose Yagi antennas, which are similar to fish skeletons. The advantage of this directional antenna is that the gain value is higher, but the disadvantages are equally obvious. Its structural size is relatively small. The larger the size, the more space it takes up. Therefore, the drone jammer guns produced during this period look a bit bulky in appearance, and the level of craftsmanship is not good.

Later, with the optimization of the appearance of the drone jamming gun and the reduction of the size of the equipment, it will require the use of some smaller directional antennas. At this time, the manufacturers of the drone jamming gun began to generally choose Logarithmic period antenna, this logarithmic period antenna adopts the form of PCB printed board, and the size of the antenna itself has been greatly reduced, which provides convenient conditions for the miniaturization of drone jamming guns. The disadvantage of the printed board antenna is that the gain value of the RF signal is not very high, generally only 8-10dB.

In addition, there are also a very small number of drone jamming gun manufacturers who choose less common horn antennas, bowl antennas or parabolic antennas, etc. These are only used in very individual special application environments, here we are It will not be explained in detail.
