Fast Facts about this Product:

  • This repeater kit is best for: Users who need to provide in-vehicle amplified cellular signal to 2 to 3 cellular modems or phones in close proximity to the included "candy bar" antenna.
  • Coverage area*: 3-5' (e.g. front seat area of a vehicle)
  • All-in-One Kit? YES
  • 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 Cellphone-Mate SureCall™ CM2000-WL Mobile Amplifier is a high-performance DC or AC powered amplifier that powerfully boosts both the incoming and outgoing signals of most cell phones by up to 10,000 times.

With the SureCall™ amplifier doing all the long-range work, the battery on your cell phone drains much more slowly, thereby dramatically increasing your talking time. This third-generation product is more efficient and more signal-sensitive than previous models. It runs cooler. Finally, it moves 95% of the RF radiation that carries the cellular signal away to a safe distance from your brain and body.

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 5' of separation between the outside and inside antennas. Separation can be horizontal or vertical.
  • The magnetic mount antenna MUST be connected to something magnetic or it will not work! A suction cup window mount, which provides a magnetic base for the antenna, is available separately if needed.
  • The inside antenna should be mounted within a couple of feet of where boosted signal is needed. In a typical vehicle, the best place to mount the inside antenna is shoulder height on the side of the drivers seat. Remember, the closer your phone is to the interior antenna, the better the performance.
  • Do not mount the interior antenna within 4" of metal.
  • You CANNOT use a traditional adapter cable that plugs directly into an antenna port on a phone/modem with this amplifier - doing so will damage your device! If you want a direct connect amplifier, purchase the 811201 Direct Connect Amplifier

The unit is great and i would like to be able to use it at home as well in my car. Do you sell a longer external atenna cable? If not do you know where i might find a long cable?
