Fast Facts About This Product:

  • This antenna is best for: People looking for a replacement for the antenna that comes with mobile amplifiers or users of routers/gateways that use SMA/female antenna connectors.
  • Compatibility: 700mhz/800mhz/1900mhz/2100mhz networks, which are used by most 2G, 3G, and 4G providers in the USA, including:
    • Verizon 2G/3G/4G
    • Sprint 2G/3G/4G LTE (does NOT work with 4G WiMAX!)
    • AT&T 2G/3G/4G/LTE
    • T-Mobile & MetroPCS 3G/4G only where 1900/2100mhz is being used (these carriers also use the 1700mhz band in some areas; this antenna will NOT help in those cases).
    • US Cellular 3G/4G
    • Datajack 3G
    • Virgin Mobile 3G
    • For other carriers, confirm which frequency your provider is using and make sure this antenna supports it before purchasing! Contact us if you need any assistance.
  • Height: 12" tall.
  • Cable: 12.5' RG174 attached to antenna
  • Ground Plane: This antenna MUST be attached to a metal surface in order to function! An 8"+ diameter ground plane is recommended (the roof of a car/truck is perfect); a Suction Cup Window Mount is available for using the Mag Mount antenna indoors or where a metal ground plane is not available.
  • Weatherproof? Yes, this antenna can be used outdoors and is made for use on a vehicle's metal/magnetic rooftop.
  • Mounting Requirements: This antenna MUST be attached to a metal surface but does not require permanent mounting (i.e., no drilling, screwing, hardware, etc is required). A Suction Cup Window Mount is available for using the Mag Mount antenna indoors or where a metal ground plane is not available.
  • Portability: The Magnetic Mount antenna is portable but does require a metal ground plane to function. You must attach the antenna to either an 8"+ metal ground plane or the Suction Cup Window Mount, reducing its flexibility slightly.

Do a site survey before buying this antenna! If you're purchasing this to use in just one location, we strongly recommend doing a site survey first to determine whether the antenna will help your signal and performance and to give you an idea of what kind of results you can expect from it.
