For absolute jamming of any cell phone signal, there is no stronger or more efficient solution than the  5 Antennas High Power 3G 4G Cell Phone Jammer . This high quality device provides you with 10 Watts of output power and 5 powerful high gain antennas to completely block all mobile phone signals within 5-20 meters.

When complete cell phone silence is needed, this 5 antennas high power 3G 4G cell phone jammer is the answer. With its five high gain antennas, you get industrial-strength frequency jamming that is powerful enough to disrupt all cell phone signals (4G, 3G, GSM, CDMA, DCS). It also provides 10 Watts of output power that will even jam the strongest signals, which usually cannot be stopped by the lower 3-5 Watt versions.

With a working radius of up to 20 meters, this device can be used in any location and even mounted on the wall thanks to the mounting plate and included accessories. Just put it in places where a phone call would be particularly disruptive because silence is expected or needed, and you'll get instant  jamming. For example business meetings, legal proceedings, churches, hospitals, movie theaters, class rooms, etc. Best of all, this 5 antennas high power 3G 4G cell phone jammer will not interfere with other electronic equipment in any way!
