XM Satellite Radio increases the quality of your boating time with over 170 channels of quality programming. Terk designed the high-performance XMARINE marine antenna to provide crystal-clear XM Radio reception on the water.

The antenna will withstand extreme environmental conditions — its sealed housing is impervious to damage from salt water or bad weather. The antenna installs using the standard marine mounting bracket, and the 25' cable connects to any XM tuner with a single antenna input.

Important Note: You must subscribe to XM Satellite Radio to receive the satellite radio signal. XM satellite radio has an offshore range of at least 100 miles (or more, depending on your location) off the coast of the lower 48 states; service is not available in Alaska or Hawaii.

Product Highlights:

  • marine antenna with water-proof sealed housing
  • mounts to standard marine bracket (1-1/4" thread)
  • designed for use on any power or sail boat
  • 25' cable included
  • dimensions: 3-3/4"H x 1" (maximum diameter)
  • warranty: 1 year
  • Our 60-day money-back guarantee

Crutchfield Customer Review (What's this?)

Wish that you could have recommended a mount for this item, chatted with someone and they weren't able to find one that y'all carried. Other than that we are pleased so far, hope to try it out in the water this weekend!

Pros: Good size!

Cons: Need mounts to go with it!

easy to install

Crutchfield Customer Review (What's this?)

Easy to install by drilling hole through fiberglass. Wish the antenna itself was smaller diameter. Make sure your surface to install antenna is flat. Had to seal with silicone.

Pros: easy to install

Cons: larger than expected out of box

Worth it

Crutchfield Customer Review (What's this?)

If you go XM on your boat get this antenna. Where we go phone reception is not good so Pandora is not an option and regular FM is bad. This keeps the XM going all day.

Pros: Works great

Cons: Expensive but worth it

Crutchfield Customer Review (What's this?)

Returned. Have Garmin XM weather/radio GPS and was not comparable with current setup. Currently using Garmin XM antenna for both radio and GPS which will function for both. The Xmarine will only work with radio.

Crutchfield Customer Review (What's this?)

After searching for a special application antenna. I discovered that the x-marine would be perfect. I had a unique installation since I already have a vehicle with a hole in the roof, and have been searching for a surface mounted antenna. Also the high db gain of this antenna has give me nothing but perfect signal strength including under heavy tree cover, interstate overpasses, and other areas that the magnetic antennas would drop out. Thanks again for your exellent customer service.....



a great upgrade for your car/truck

Written by: anthony from florida on March 20, 2009

I wanted to give this antenna a try even though its called a marine antenna.... i like the tech. specs of 30 db increase. I installed it on my 2005 xterra. the antenna is the size of a hockey puck and its 2 parts. the bottom base can unscrew from the top antenna area.... wich makes it easy to mount on top of my bin on my rack... i drilled a hole on the plastic bin door and i drilled a hole through my interior light area that goes into the storage bin. I am very impressed with the performance..... in areas where i would loose the signal, i am not loosing signal. I am very please with this antenna and hope that others will take advantage of the marine specs for better signal. the only modification was on my xm receiver i had to use some small plastic cutter to remove the housing for the usual xm car antenna and allow the marine plug to slide into place. Great product. (i painted mine with dupli-color bumper black to blend to my roof rack
