After purchasing and installing our SMa-818K200 high-power frequency jammer, the customer installed it on the top of the building in the unit, because of the selected omnidirectional antenna, and a set of frequency jammer is equipped with multiple mobile phone frequency bands There are multiple modules and corresponding omnidirectional antennas. The customer asked a question, how to do a unified installation, protection and beautification of these multiple antennas, so that they can work stably and effectively without looking so dazzling.
According to the customer's requirements, we specially designed an omnidirectional antenna protection device for the antenna installation of the SMa-818K200 high-power frequency jammer. The radome body of the upper part of the antenna protection device is made of glass fiber reinforced plastic, which is made by mold opening and turning. Because the fiberglass material has very little 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 frequency jammer will be weakened.
The lower part of this high-power frequency 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 RF feeder of the frequency jammer passes through the middle tube, one end is connected to the radio frequency end of each internal omnidirectional antenna, and the other end is connected to the output interface of each frequency band of the frequency jammer.
