XM Clamshell South Facing Instructions - Install Indoors

Step 1: Do You Live in a Major Metropolitan Area?

Step 1 will provide quick instructions to determine if you can receive the terrestrial repeater signal. Otherwise, begin with Step 2. SiriusXM has terrestrial repeaters in major metropolitan areas. These ground-based repeaters transmit the SiriusXM signal into your home or office, eliminating the need to aim the antenna at a satellite. Follow these instructions for a quick test to see if you can receive the terrestrial signal.

If you're receiving a terrestrial (ground) (TER) signal, try experimenting with the antenna to get a feel for the reception in your location. Move the antenna around the room, from room to room, and aim it toward different windows. In major metropolitan areas, you might find that you get great reception in several locations without worrying too much about aim and placement. If you find a location where there's good terrestrial signal strength, place the antenna there. The installation is complete.

Step 2: Place the Antenna

Find a suitable window in your home or office that faces south.

• This window needs to have a clear, unobstructed view of the sky.
• There should NOT be any blinds or curtains between the antenna and the glass window pane.
• There should NOT be any metal screens or bars on the window.
• There should NOT be any buildings, shrubs, trees, roof overhangs, or anything else obstructing the antenna's view of the south sky (see below).






Place the antenna on the windowsill of a suitable window that faces south. Not sure which way is south? Think about where the sun rises (in the east) and sets (in the west). Then stand so that east is to your left and you'll be facing south.
Note: If placing the antenna on the windowsill results in the antenna directly facing the window's frame, place a book or other flat object under the antenna to prop the antenna up so that it is facing the glass window pane.
