Fast Facts About This Product:

  • This amplifier is best for: Verizon 4G 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 Verizon 4G LTE devices.
  • Coverage area*: 4,000 - 10,000 square feet
  • All-in-One Kit? NO - antennas and cabling are required (sold separately)
  • Compatibility: Verizon 4G LTE on the 700mhz frequency only (NOT the AWS band Verizon also uses for LTE in some areas) - this amplifier will NOT work for ANY other networks (not even AT&T LTE - AT&T uses a different portion of the 700mhz frequency for their LTE network; AT&T users should use the CM700A-70 amplifier).

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® CM700V 70dB amplifier is dedicated to improving data service on the Verizon LTE network. This amplifier is designed for large homes, offices and warehouses 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.

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' of separation between the outside and inside antennas (if you are using an omnidirectional antenna as the outside antenna, you will need more separation than directional antenna users will need). Separation can be horizontal or vertical.
  • 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.
  • If you are using a panel antenna as the interior antenna, make sure it is aimed AWAY from the outside antenna.

Verizon had to relocate some towers in my area when a new landlord did not want a tower on their property anymore. My 3G service, already barely acceptable stayed the same, but my 4G service, also barely there, practically disappeared. by getting some short cables, two diplexers, and a 4G amplifier, and a directional panel antenna to add inline with my 3G amplifier, my 4G service was restored to its previous levels. It was not great to begin with, but it worked again, which is important for me since I work form home and Verizon wireless is my only Internet option. Thanks, 3G store.

Needed to use external antenna with multiple Pantech UML290 cell modems. Works like a champ. Performance increase is remarkable. A must-have.

I ordered the Verizon repeater and an outdoor panel antenna, and the indoor dome antenna. I was in the overnight shipping area and the product arrived the next day everything was intact. We installed the repeater and antennas following the instructions, used good quality LMR-400 cable between both antennas, observed the proper spacing between both antennas, set up the repeater and it works perfect. I'm 100% satisfied with the product and the 3G store customer service.

We were very happy with this amplifier. We doubled our Verizon 4G LTE speed from the single digits to the double digits. This device amplifies both upload and download speed. We had side by side comparison with Wilson and found this worked much better. The Wilson only increased download speed. We've now had 3 installed for over 2 months and found very reliable operation.
