Fast Facts About This Product:

  • This amplifier is best for: Users with direct line of sight to the cell tower (necessary because this kit includes a directional Yagi antenna) who need to provide amplified cellular signal to multiple 3G and Verizon 4G modems or phones in a home or office up to 5000 square feet and have the space to accommodate the 60-80' of separation between the outside and inside antennas that this kit requires.
  • Coverage area*: 1,000 - 5,000 square feet
  • All-in-One Kit? YES
  • Compatibility: This amplifier supports 800mhz/1900mhz networks (which includes most voice/2G and 3G providers in the US) as well as the 746-787mhz Verizon 4G LTE network. Supported carriers/networks include:
    • Verizon 2G/3G/4G
    • Sprint 2G/3G
    • AT&T 2G/3G and HSPA+ (which shows up on your device as "4G" - NOT LTE)
    • Datajack and Virgin Mobile 3G
    • T-Mobile and Cricket 2G
    • Does NOT work with 4G LTE from AT&T/Sprint/US Cellular/MetroPCS, WiMAX (Sprint/CLEAR 4G), Nextel/iDen, or AWS (T-Mobile 3G/4G and Cricket 3G)

IMPORTANT SIGNAL INFORMATION: If you're purchasing an amplifier for use at one specific location, we strongly recommend doing a site survey first to determine whether the amplifier will help you and to give you an idea of what kind of results you can expect from it.

If your signal is extremely poor (-108db or worse), an amplifier may not be effective - there must be some usable signal available for the amplifier to boost. Conversely, if the signal is too STRONG at your location (-50db or better), the amplifier may shut down to avoid interference with the tower.

Designed for Verizon customers, the Tri-Flex V is part of the Enhance series of residential and small business boosters. This completely integrated booster combines Cellular, PCS and the Verizon LTE band to dramatically improve 3G and 4G LTE speed. This full-featured booster includes manually adjustable gain control with dials for each band and automatic shutdown for maximum flexibility. Ideal for large homes and small office buildings, warehouses with low cell signal.

How it works: The outside antenna picks up the cellular signal and sends it through the first cable to the amplifier. The signal is then boosted and sent through the second cable to the inside antenna, which rebroadcasts the boosted signal. All of your modems/phones within range of the inside antenna can benefit from the boosted signal wirelessly.

*Many factors will influence the actual coverage area you will see from a repeater, including layout/floorplan, construction, and original un-amplified signal strength. Depending on your situation, you may see more or less coverage than the estimates listed here. It is not possible to guarantee coverage area.

Installation notes:

  • In order for your system to function properly, you must maintain adequate separation between the outside and inside antennas (if the antennas are too close together, there will be oscillation/feedback between the antennas and the amplifier will shut down). This amplifier requires approximately 60-80' of separation between the outside and inside antennas. Separation can be horizontal or vertical.
  • The Yagi antenna must be aimed directly at the cell tower - if it is not aimed properly or if there are too many obstructions between it and the cell tower, it will not be effective. If you don't have line of sight to the cell tower, we recommend buying the kit with the omni antenna instead.
  • If you cannot achieve adequate separation to eliminate oscillation, you can turn down the gain on the amplifier, but that will result in a smaller coverage area from the amplifier.
  • The interior antenna should be at least 10' away from the amplifier.
  • Make sure the panel antenna is aimed AWAY from the outside antenna.

I purchased this cell / 4G amplifier for a metal building in an area that has sketchy cell / 3G-4G signals outside the building and ZERO reception inside the building. After installing the Cell phone Mate - Exterior Antenna - Cables - Interior Antenna - my cell reception went from -110 dBm outside the building to -95 dBm inside and - solid 4G inside with speed test of 16-20 megabytes per second download and 6-18 megabytes per second upload - as long as it keeps working I am very happy I purchased this amplifier

As long as it keeps working, it's impressive. Verizon MiFi went from -93dB to -36dB... that's like 7 bars!. Much improved over the other models. Better power supply, adjustable gain, with auto shutoff protection makes it much less fragile than previous models( AND BRANDS) that I've used.

We are covering in excess of 50,000 square feet of our manufacturing facility using 2 antennas and getting 4G in the whole area. Without the amplifier we can't get a signal at all. We couldn't be happier. This is well worth the money!
