Can the placement be adjusted to increase the coverage of the shielded signal?
After purchasing a portable mobile phone signal jammer, some customers put the shielding device into actual combat tasks very enthusiastically, but sometimes they would feedback some information: the coverage of the shielded signal is a bit small. And after changing different working environments, I feel that the shielding distance of the shielded signal is relatively large in some scenarios, and relatively small in some scenarios. Ask us what is going on?
First of all, the transmission power of the portable cell phone jammer itself is fixed. That is to say, the strength of the shielding signal emitted by it is relatively stable and will not fluctuate. In different environments, there will be several factors that affect the coverage of the shielding signal, such as: the distance of the base station, buildings or The error of the wall obstacle, etc., these will directly affect the effective shielding distance of the shielding signal.
Secondly, the placement of the portable mobile phone signal jammer is also critical. Since the height of its main box is about 70cm, its antenna is directly screwed on the main box, that is to say, if the portable mobile phone signal jammer is placed directly on the ground, the height of its transmitting antenna from the ground will generally not exceed 1 meter. To increase the coverage of the shielded signal, the easiest 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 shielded signal will increase greatly.
So, what are the advantages of increasing the height of the antenna? We suggest that users should first observe the terrain and terrain, and try to choose the highest point to place the portable mobile phone signal jammer. Or use some desktops, steps or buildings, etc., and try to use these positions to increase the height.
In addition, there is another way: you can choose our company's antenna bracket, connect the antenna of the portable mobile phone signal jammer with the host through a 3-meter-long feeder, and install the antenna on the bracket. Our customized antenna bracket can The antenna is propped up to a height of 3 meters.
