After purchasing and installing our high-power cell phone signal jammer, the customer installed it on the top of the building in the unit because of the selected omnidirectional antenna, and a cell phone signal jammerinstrument is equipped with multiple cell phone frequency bands There are also many corresponding omnidirectional antennas for the module. The customer asked how to do a unified installation, protection and beautification work for these multiple antennas, so that they can work stably and effectively without looking so dazzling.
According to the requirements of customers, we specially designed an omnidirectional antenna protection device matched with the antenna installation of high-power mobile phone signal jammer. The antenna cover body of the upper half of the antenna protection device is made of glass fiber reinforced plastics, and is formed by opening the mold and turning it over. Because the attenuation of the radio frequency signal emitted by the antenna is very small, there is no need to worry about whether the shielding signal transmission effect of the internal mobile phone signal jammer will be weakened.
The lower part of this high-power mobile phone signal shielding instrument protection device is made of stainless steel, which is used for stable installation on the cement layer or steel frame structure on the top of the building. The radio frequency feeder of the mobile phone signal jammer is connected to the radio frequency end of each internal omnidirectional antenna through the intermediate tube, and the other end is connected to the output interface of each frequency band of the mobile phone signal shielding instrument.
