Fixed Mast Antenna; Xm™ Satellite Radio Antenna System - Saturn 2006 Ion Owner's Manual

Fixed Mast Antenna

The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, straighten it out by hand. If the mast is badly
bent, replace it.
Check occasionally to make sure the mast is still
tightened to the antenna base located on the hood of
the vehicle. If tightening is required, tighten by hand.
