Users of USB modems, hotspots, and embedded modems that use a connector type OTHER than SMA will need an adapter cable or connector to connect the antenna to your device AND an SMA to FME adapter (if your device has an SMA/Female connector, you will NOT need any adapters). If you already own the necessary adapter or if your device has an SMA/Female antenna connector, you can select the "I already have an adapter" option from the bottom of the list.
Select Your Adapter Cable or Connector (required) - details
This antenna has an SMA/Male connector. If you will be using it with a traditional adapter cable or an amplifier with an FME/Male connector, you MUST add the SMA to FME adapter.
Add SMA to FME Adapter (required for most users!) - details
This antenna does NOT include mounting hardware. We recommend adding this 3-way mount unless you already own a compatible mount.

This antenna is the SAME as Wilson's old model #301133, but with an SMA/Male connector. Users of hotspot devices, USB modems, and other equipment that does not have an SMA/Female antenna connector will need both the adapter for your device AND an SMA to FME adapter (see above). 

Fast Facts About This Product:

  • This antenna is best for: RV users needing to boost 3G or LTE signal. Its spring base and shorter 21" height make it our most popular RV antenna.
  • Compatibility: 700-1900mhz networks, which are used by most 2G, 3G, and 4G providers in the USA and Canada (not appropriate for T-Mobile or some Canadian 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: 21" tall
  • Cable: 13.5' of RG-58 cable hardwired to the antenna.
  • Ground Plane: The Omni RV Antenna uses included radials as a built-in ground plane.
  • Weatherproof? Yes, this antenna is designed for exterior use.
  • Mounting Requirements: The antenna can be installed in a standard 3/8" x 24 threaded "CB" mount OR you can use the optional 3-Way Mount (see above) to mount it to the sideview mirror frame on a truck/RV/coach, RV ladder frame, boat, or outside of house/office.
  • Portability: This antenna is designed to be mounted to an RV, usually to the ladder on the back. The optional mount does attach with standard bolts, so it is not necessarily a "permanent" installation, but it is not compact or easily transported.

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.

Product works great with the Wilson sleek. Install signal strength by 2 to 3 bars. Worth the investment
