XM Satellite Radio connectivity is becoming more common on Home Theater Receivers.
Pictured on this page is the XM Radio Mini-Tuner inserted into its Home Dock and Antenna, both items must be purchased separately. As you can see they are both very compact. The tuner is on the left side of the ruler and the Antenna is just to the right. The antenna plugs into the Tuner Home Dock. There is plenty of cable length provided with the Antenna so you can properly position it for best reception from the XM satellite. On the far upper right corner of the photo is the XM connection on the back of a Home Theater Receiver that the XM Radio Mini-Tuner plugs into.
