After the customer purchases and installs our SMa-818K200 high-power mobile phone signal jammer, it is installed on the top of the building in the unit, because of the selected omnidirectional antenna, and a set of mobile phone signal jammers is equipped with multiple The mobile phone frequency band module also has multiple corresponding omnidirectional antennas. The customer asked questions, how to do a unified installation, protection and beautification of these multiple antennas, so that they can work stably and effectively without looking so garish.
According to the customer's requirements, we specially designed an omnidirectional antenna protection device for the antenna installation of the SMa-818K200 high-power mobile phone signal jammer. The radome body of the upper part of the antenna protection device is made of fiberglass, which is made by mold opening and turning. Because the fiberglass material has a very small attenuation of the radio frequency signal emitted by the antenna, 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 jammer protection device is made of stainless steel, which is used for stable installation on the concrete layer or steel frame structure on the top of the building. The radio frequency feeder of the mobile phone signal jammer passes through the intermediate tube, one end is connected to the radio frequency end of each internal omnidirectional antenna, and the other end is connected to each frequency band output interface of the mobile phone signal jammer.
