Fast Facts About This Product:
- This amplifier is best for: AT&T and US Cellular4G LTE users looking for a powerful wireless amplifier to provide boosted signal to multiple LTE devices in a large home/office and have the space to accommodate significant separation between the antennas (60' of separation between the external and internal antennas is recommended). This amp is ONLY appropriate if you are ONLY needing to boost signal to AT&T or US Cellular 4G LTE devices (it will not affect 2G or 3G signal or 4G signal for other carriers, nor will it work for Verizon LTE - click here for the Verizon version of this amp)
- Coverage area*:
- All-in-One Kit? NO - antennas and cabling are required (sold separately)
- Compatibility: AT&T and US Cellular 4G LTE ONLY!
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 SureCall® CM700A 70dB amplifier is dedicated to improving data service on the AT&T LTE network. This amplifier is designed for large homes, offices and warehouses (2000 – 30,000 sq. ft.) operating on the LTE 4G frequency where users currently are not getting a strong 4G signal due to geographic location, building materials or structural design.
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.
