Sirius XM Radio Motorcycle Antenna with GoPro Adjustable Strap Mount New

Product Description

MEET THE LATEST INNOVATION IN SiriusXM Radio ANTENNAS

The MTSTRP21 SiriusXM Radio motorcycle and UTV antenna features an adjustable strap mount that makes it easy to install on motorcycles, UTVs, and any other installation that requires an adjustable strap for mounting.

If you have a Gold Wing, Harley-Davidson or other motorcycle with large round bars or square bars you know how hard it is to find a SiriusXM Radio antenna that can mount on your bars. We listed to our customers and matched up our adjustable strap mount with our motorcycle antenna with a GoPro mounting base for a quick and simple solution. The strap opens up all the way to allow for installation on various types of bars. To remove the antenna simply lift up on the release tab and pull the strap back. The GoPro mounting base allows the antenna to pivot almost 180 degrees so you can mount the antenna horizontally or vertically.

This antenna is also perfect for installing on Polaris UTV side-by-side vehicles and other utility vehicles with roll cages or roll bars. The strap fits on handlebars or roll bars 15mm to 50mm in diameter and is made of fiber glass and is built to work under extreme conditions.

Antenna Features
