The Sirius Echo Signal Repeater System (SIRWRS1) is a system that allows you to place your Sirius receiver in places you never thought you could. Where before you were bound by antenna cables spanning in and out of your house, now all you need is this system to send the antenna signal through wireless transmission.
This unit is comprised of two parts. The base station: this is where you connect your Sirius antenna to.Combined with Sirius Extension cables you can place it in any indoor room. Your Sirius antenna must be in a position to receive satellite signal for the system to be effective.
The second piece is the piece you connect to your Sirius receiver. It will directly plug into the ANT port on the receiver just like if you were using the regular antenna. You can place this piece up to 75ft uninterrupted, transmission range is lessened by other wireless devices and obstructions( ie walls, concrete,and of course a 1983 Volkswagen Scirocco). Cordless phones and WiFi internet can also degrade the signal.
All-in-all this unit will give you the freedom to place your Sirius Radio where ever you desire.
