After purchasing the portable signal jammer, some customers are very enthusiastic about putting the jamming equipment into the actual combat task, but sometimes they will feed back some information: they feel that the coverage of the jamming signal is a little small. Moreover, after changing different working environments, I feel that the interference distance of the interference signal will be larger in some scenes and smaller in others. Ask us what's going on?

Firstly, the transmitting power of portable signal jammer is fixed. In other words, the intensity of the interference signal transmitted by it is relatively stable and will not be large or small. Under different environments, there are several factors affecting the coverage of the interference signal, such as the distance of the base station, the error of building or wall obstacles, which will directly affect the effective interference distance of the interference signal.

Secondly, the placement position of portable signal jammer is also key. Because the height of its main box is about 70cm, its antenna is directly screwed on the main box, that is, if the portable signal jammer is directly placed on the ground, the height of its transmitting antenna is generally no more than 1m from the ground. The simplest way to improve the coverage of jamming signals is to increase the height of the antenna from the ground. When the height of the antenna increases, the effective jamming distance of jamming signals will be greatly increased.

So, what are the advantages of increasing the height of the antenna? We suggest that users should first observe the terrain and terrain on the site, and try to select the highest point to place the portable signal jammer. Or use some desktop, steps or buildings to increase the height of portable Signal Jammer by using these positions as much as possible.

In addition, there is another way: the antenna support of our company can be selected to connect the antenna of the portable signal jammer with the host through a 3M long feeder. The antenna is installed on the support. Our customized antenna support can raise the antenna to a height of 3M.
