I have a nearly new cell phone jammer for sale - range is approximately 30 metres in radius. Model MONIX MGB-1S cellular Jammer.
Used only one week ( and then the tenant was gone! - hint great for getting rid of loser tenants who depend on their cell phones for calls).
Includes unit, plus 2 attennas, and a power cable and transformer for North American Standard power.
Asking price $395 plus shipping.
Please email me at donestuardo (AT Sign) yahoo.com or call me on my cell at (416) 458-0012 and I will be happy to go over details with you.
