The SureCall Tri-Flex Signal Booster Kit by Cellphone-Mate is a wireless signal booster that can amplify the 2G and 3G networks from most major carriers plus a single 4G LTE frequency. Until now, most signal boosters were either dual-band and only boosted 3G and earlier signals or they were LTE specific and only boosted the LTE signal. This amplifier combines the two and boosts both the dual-band and LTE frequencies.

The SureCall Tri-Flex repeater features a powerful 65 dB gain which gives it a total coverage area of up to 6,000 sq ft (depending on existing outside signal strength) when paired with the included omnidirectional antenna making this the ideal amplifier for large homes and small to medium offices. Because this is a powerful amplifier, you must have a minimum of 20 ft of vertical separation between the inside and outside antennas. Adding up to 75 feet of horizontal separation can help improve the performance of this signal booster by minimizing the potential for oscillation (feedback) between the inside and outside antennas.


Kit Options

This SureCall Tri-Flex Signal Booster Kit has two options that you can select when purchasing.  First, you'll have to choose your amplifier.  The three choices are:

  • Tri-Flex for AT&T & US Cellular 4G LTE - The Tri-Flex-A Amplifier supports most major 2G and 3G carriers plus the AT&T & US Cellular 4G LTE networks.
  • Tri-Flex for Verizon 4G LTE - The Tri-Flex-V Amplifier supports most major 2G and 3G carriers plus the Verizon 4G LTE network.
  • Tri-Flex for T-Mobile, MetroPCS, Cricket, and Canadian Carriers (AWS) - The Tri-Flex-T Amplifier supports most major 2G and 3G carriers plus T-Mobile's 4G and 4G LTE networks, MetroPCS 3G and 4G, Cricket, and the 4 main Canadian Carrier LTE networks from Bell, MTS, Rogers, and Telus.
The second choice determines the type of inside antenna you want.  The two options are:
  • Dome Antenna - Best for covering a single floor. Mounts on the ceiling in the middle of the space.
  • Panel Antenna - Best for covering multiple floors, or long narrow spaces.  Can be mounted on a wall or a ceiling facing down.
