In the procurement of portable cell phone signal jammer, some customers are very enthusiastic to put the shielding equipment into the actual task very quickly, but also sometimes feedback back some information: the shielding signal coverage is a little on the small side. And after replacing the different working environment, feel the shielding distance of the shielding signal, some scenes will be larger, while some scenes are smaller, ask us what's going on?

First of all, the portable signal jammer itself is a fixed transmitter power. That is, the strength of the shielding signal it emits is relatively stable, will not be big or small, different environments, there will be several factors affecting the coverage of the shielding signal, such as: the proximity of the base station, the error of the building or wall obstacles, etc., which will have a direct impact on the shielding signal of the effective shielding distance.

Secondly, the placement of the portable cell phone signal jammer is also more critical. Because of its main chassis height of about 70cm, its antenna is screwed directly to the main chassis, that is to say, if the portable cell phone signal shield is placed directly on the ground, then its transmitter antenna height from the ground is generally not more than 1 meter. To enhance the coverage of the shielding signal, the simplest way is to increase the height of the antenna from the ground, when the height of the antenna increases, the effective shielding distance of the shielding signal will be greatly increased.

So, what is the height of increasing the antenna? We suggest that the user should first observe the terrain and terrain at the scene, and try to choose the position of the highest point to place the portable cell phone signal shield. Or use some desktop, steps or buildings, etc., try to use the portable cell phone signal shield to increase the height by using these positions.

There is another way: you can choose our company's antenna bracket, the portable cell phone signal shielding antenna and the host through the 3-meter feeder cable for connection, the antenna is mounted on the bracket, our customized antenna bracket, you can support the antenna up to a height of 3 meters.
