Call For Availability

Item Number: 5239



Sales Tax (?):

$0.00 tax collected outside of Illinois

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 item ships from an alternate location - shipping may be delayed. Contact us before ordering if you need a more exact ETA.

This antenna is the SAME as Wilson's old model #301119, 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 who like the idea of the through-roof mount (as opposed to mounting the antenna on the ladder/mirror and running a cable in).
  • Compatibility: 700-1900mhz networks, which are used by most 2G, 3G, and 4G providers in the USA and Canada (not suitable for T-Mobile or some Canadian providers). Confirm which frequency your provider is using and make sure this antenna supports it before purchasing! Contact us if you need any assistance.
  • Height: 18" tall
  • Cable: 13.5' of RG-58 cable hardwired to the antenna.

Between the antenna and the Sleek my MIFI works great. Very happy with the product and service.

Even after reading the prior reviews, I was skeptical first about the quality of the product, and more importantly of whether it could help my problem. Let me deal with the first concern first: the antenna is made by Wilson and I was extremely impressed with the build quality, the packaging, the instructions---all first rate. Installation was through the roof of my motorcoach. The National Weather Service is reporting a heat index of 104 here today, so I was dreading climbing on the roof and installing the antennas (I bought two as I have both a Sprint and a Verizon aircard) but it was straightforward; much easier than I anticipated. Took about 30 minutes for both antennas.

As to performance, I'm just amazed. I'm currently parked at Isla Blanca RV park at South Padre Island, Texas. I had been unable to get a Sprint connection at all and my Verizon would grudgingly give me poor and unreliable EVDO service. Now, with the antennas connected, I get four bars and -40db LTE reliably on the Verizon, and two bars -80db on the Sprint. The Sprint is EVDO and a bit flaky, but I couldn't get it at all before, even having tried taking the Cradelpoint 1200 router with the aircards up onto the roof (I was desperate!) so getting even mediocre Sprint speeds is a huge improvement.

I can't say enough about these. Highly recommended.
