Does your Sirius or XM Radio receiver have a Pink cover around the antenna port? If so then this adapter will allow you to use any Sirius or XM Radio antenna with your receiver. One end of the adapter has a standard SMB jack to connect to your antenna. The other end has a Pink FAKRA housing to connect to your receiver for a secure connection. Now you can use any standard SIRIUS XM antenna with your radio by connecting this adapter cable. You can now use a marine, motorcycle, thru-glass, or other antenna even if you have a FAKRA connection thanks to this handy adapter!
