There is also an adjustable control switch, which can control the shielding distance arbitrarily.
Power goods! worth the money!
It has been used for a while, and it can be used continuously for a long time, and the performance is very stable. The only downside is that the cooling fan can be a bit noisy, but it's still a good product. Recommend buying it!

A good jammer! The signal is all gone. recommend it! Works perfectly!
Delivery was very fast. and service is very good.
The package I received today is quite heavy, and it is estimated to be close to 10kg. The installation of the equipment is very simple, but it is a bit time-consuming to install 22 antennas, but it can be used after installing the antennas. Its shielding performance is very strong, and each antenna can be adjusted. power of the antenna. Very powerful jamming device!
