Before you set off on your next boat trip, make sure you can hear your favorite SIRIUS Satellite Radio stations onboard. Terk designed the SIRMarine satellite radio antenna to provide crystal-clear SIRIUS reception on the water.

This rugged marine-rated antenna can withstand splashes of salt water and high vibration from wind. You can mount it directly to your boat's deck or use the supplied adapter to attach it to a bracket or mast.

Note: A subscription to SIRIUS is also required. Satellite radio service is available only within the lower 48 states — not available in Hawaii or U.S. territories. Limited service is available in Alaska.

  • marine antenna for SIRIUS Satellite Radio
  • threaded flange adapter and 24.5' antenna coax cable included

Easy to install. Worked great on my Sea Ray boat. Mounted on my radar arch. Reception has been perfect at the pier and on the water.

Great Antenna For My Boat

Doug from Alabama on 5/31/2015

Crutchfield Customer Review (What's this?)

I added a SiriusXM tuner to my marine head unit on my boat. I purchased the Terk SIRMarine antenna and mounted it to the deck just above the helm. Installation was easy and took minutes to complete. Instantly I was listening to SiriusAM radio and enjoying great music anywhere on the lake. Great purchase. I highly recommend this to anyone needing a satellite radio antenna for a marine installation.

Pros: Easy to install, 25' of antenna wire, weather proof, works very well.

Cons: None

Crutchfield Customer Review (What's this?)

Put this on my Regal, and it was super easy to install. Flush mounted it on my Cuddy, hooked up to a SC-C1 and the sound is incredible. Even underneath the tent garage, the reception is incredible!

Pros: Easy to install, long wire, great instructions.

Cons: None.

Crutchfield Customer Review (What's this?)

Antenna works good. Loose signal occasionally, sometimes due to bad weather and wave action sometimes just because. Outtages are of short duration. Can not say if another antenna would be better or if I'm just far enough north to have signal problems. Works way better than a car top type antenna I had before. The only problem I had with the antenna is this is my second one I've had to buy. Replaced this antenna a year ago and now having to get a new one . Hope this one works longer.



SIRIUS'ly connected

Ak.Yeti from Ketchikan, Alaska on 10/22/2008

I set this unit up with my SIRIUS radio on a boat and ran inside waters between Tacoma, Washington and South East Alaska without losing the signal at any time. This is an area were expensive satellite phone service often fails. Factor in the mounting options and you have an excellent package.




Hands-on research

Product Research



Overview: The TERK SIRMarine (SIRIUS Satellite Radio Marine Antenna) is a high-performance antenna designed specifically for Sirius Satellite Radio reception on recreational marine craft such as fishing boats, sport boats, yachts, and sailboats. This package includes a rugged, low-profile marine-rated antenna which can withstand high-vibration and salt-water environments, a plastic treaded flange adapter for bracket or mast mounting (mast or bracket not supplied), and a 24.5' length of RG174 coax cable.

Mounting: The TERK SIRMarine SIRIUS Antenna features dual mounting options.

  • Direct Mount: The marine antenna can be mounted directly to your boat's deck or any flat surface of your boat. This type of mount will require a 9/16" cut-out hole to route the antenna cable. This installation is perfect for use on small vessels.
  • Bracket or Mast Mounting: The marine antenna can be mounted to an optional bracket or mass using the supplied plastic treaded flange adapter. The flange adapter uses a standard 1"-14 marine thread. The bracket or mast is not included. This type of installation is great for large vessels and sail boats.

Note: There should be at least a 20-degree clearance from any metallic obstruction on all sides of the mounted antenna.

Connection: Then antenna features an attached 5.75" cable with a TNC connector that connects to the supplied 24.5' coax cable via its own TNC connector. On the other end of the 24.5' coax cable is a single SMB connector which plugs in your Sirius Satellite Radio receiver and marine dock.

System Requirements: In addition to this SIRIUS satellite radio antenna, you must have a SIRIUS tuner and subscription to SIRIUS Satellite Radio to receive SIRIUS Radio programming.
