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.
The Signal Indicator screen shows the strength of both the satellite (SAT) signal and the terrestrial (ground) (TER) signal. The strength of the terrestrial (ground) signal may vary, or there may be none if you are not in a major metropolitan area.
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).
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.
