Review 16 Bands High Power Blocker
I needn't to purchase more jammers, since this already put 3G 4G phone jammer and WiFi UHF VHF GPS Lojack RF jammers all in one.
Have to say that this jammer has unbelievably high power. Jammer range is very large, I had to adjust the output power to use
This jammer has very high power and can completely cover our entire conference room. Since using this jammer, our meeting has become more efficient
In addition to being heavy, this jammer has no other drawbacks. Can jamming a variety of frequency bands, but when it's on, world is quiet around.
