Fast Facts about this Product:

  • This amplifier is best for: Users looking for a powerful solution to boost signal to ONE device that doesn't have an antenna port.
  • All-in-One Kit? NO - requires an external antenna (sold separately), see above
  • 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.

How it works: The outside antenna (sold separately) picks up the cellular signal and sends it to the amplifier. The signal is then boosted and sent out through the patch antenna, which sticks to the back of your phone or hotspot.

not to scale. representative graphic only. exterior antenna is NOT included.

Installation notes:

  • The patch antenna must be stuck directly onto the back of your phone or hotspot. Your device will not benefit from the boosted signal unless the antenna is in contact with the device.
  • The patch antenna should be as close to the device's internal antenna as possible. You may need to experiment with placing the antenna in different locations on the phone/hotspot to find the optimum location.
  • For more details, you can download the complete installation guide (PDF)

I love this gear! Not only does it work, but because of their adaptive power control nothing is overloaded at cell towers.

I will always shop here for this gear 3 days to Australia... not bad!
