Fast Facts About This Product:

  • This amplifier is best for: Providing amplified signal to multiple cellular devices in a Small Office Home Office setting. Also a good option for larger RVs when used with directional panel as indoor antenna for adequate separation.
  • Coverage area*: 1-2 rooms in an average home/office
  • All-in-One Kit? NO - antennas and cabling are required (sold separately)
  • Compatibility: 800mhz/1900mhz networks, which are used by most 2G (voice) and 3G networks in the USA, including:
    • Verizon 2G/3G
    • Sprint 2G/3G
    • AT&T 2G/3G and HSPA+ (which shows up on your device as "4G" - NOT LTE)
    • T-Mobile and Cricket voice only
    • Does NOT work with LTE for any carrier or AWS (T-Mobile 3G/4G)

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.

The CM2000-WL 55/60dB provides completely wireless boosting of signals for multiple users simultaneously. It supports all cellphone handsets and service providers in the 800/1900mhz frequency bands, and is perfect for use in office enterprises, large vehicles (ships, trains, buses, RVs), or homes with multiple users. A sophisticated Protection circuit prevents damage to the amplifier due to interference or improper installation. With a Cellphone-Mate Amplifier doing all the long-range work, the battery on your cellphone drains slower, thereby increasing talk time. The 6V design runs safer, cooler and more efficient. Finally, with proper use of the CM2000-WL, dangerous hot spots are removed a safe distance from the user's body.

How it works: The outside antenna (sold separately) picks up the cellular signal and sends it through a cable (sold separately) to the amplifier. The signal is then boosted and sent through a cable (sold separately) to the inside antenna (sold separately), 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 20' of separation between the outside and inside antennas. Separation can be horizontal or vertical.
  • The interior antenna should be at least 10' away from the amplifier.
  • If you are using a panel antenna as the interior antenna, make sure it is aimed AWAY from the outside antenna.
