The Cellphone-Mate SureCall® CM700V 70dB is the first 4G LTE amplifier on the after-market dedicated to improving data service on the Verizon LTE network.  This amplifier is designed for homes, offices and warehouses operating on the LTE 4G frequency where users currently are not getting a 4G signal due to geographic location, building materials or structural design or where the signal is getting weak.  Depending on system design and outdoor signal strength, this amplifier can cover anywhere from 2,000 to 30,000 sq. ft. depending on outdoor signal level.

Please Note: This is the amplifier only.  Cables and antennas will need to be purchased separately to make a functional system.  Click Here to build a complete kit based on this amplifier.

Please Note:  This is a 700 MHz Band amplifier designed specifically for Verizon 4G LTE data.  It will not work for voice calls, 3G or 2G data or any other carriers/network technologies other than Verizon 4G LTE


In order for your system to function properly, you must maintain adequate separation between the interior and exterior antennas. This amplifier requires a minimum of 20' of vertical separation between the outside and inside antennas and a recommended total linear separation of at least 75 ft. for optimum performance.  This distance can be significantly less if directional antennas are used.  If a directional antenna is used for either the inside or outside antenna, ensure that it is not pointed at the other antenna.
