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!

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

I recently purchased a Wilson Sleek4G-V Signal Booster, Home Office Accessory Kit and Omni RV Antenna.
On my 2nd outing, I used the Sleek Booster w/AC power adapter and the Omni RV Antenna. Where I was located, the cell service ranged between 1-2 bars of 1X service to 1-2 bars of 4G service. With the Sleek Booster & Omni RV antenna, the sell service ranged 3-4 bars of 1X service to 3-4 bars of 4G service.
All in all, it does what the 3G Store says that it will do.

Great Quality. I mounted mine on the passenger side a few inches below the roof line to make sure it didn't stick up higher than the A/C unit. Really looks good. Hope it works as good as it looks! We'll find out when we start traveling next month.

I purchased this antenna because I seemed to be on the edge of a tower's range. Before the antenna, when I did a speed test I would ping at 285 ms, download 0.11 Mbps, upload 0.18 Mbps. After installing the antenna the speed test was: ping 310 ms, download 0.21 Mbps, upload 0.41 Mbps. Not an increase that I could jump up and down about.

Used this antenna mounted on a travel trailer we have parked in a remote area to receive V-mobile internet. It works great and the store was easy to shop.

Great product. It increased my download speed x3. I'm sure glad I did this upgrade.

The antenna seems to increase the signal somewhat, but not in the amount that I had hoped. As I was screwing in one of the small antennas, one of them broke off. I did not force it at all, it was just weak and broke off at the end of the screw. I have thought of calling and asking for another antenna, but I am not sure if it would make that much of a difference. I would like a new antenna to replace this one that broke. Let me know and I will give you an address to sent it to. I would be interested in a bigger antenna than this one if it would give me a much stronger signal.

Mounted on my RV ladder, it's the highest point on the roof and is taking a beating on anything low hanging. Already lost one of the wiskers on the base. Will probably have to mount it lower on the ladder to prevent any future damage.

It did a very good job.

I bought the antenna to put on my 26 ft RV. We have property in the mountains, and the only cell phone svc. is to walk to the top of the mountain. We now can send and receive messeges where we camp on the property.
