Here's an easy way to add an XM or SIRIUS magnetic-mount satellite radio antenna to a long haul truck or RV. Just clamp this sturdy bracket onto any mirror support arm (up to 3/4" in diameter) and place the antenna on it.
Installation doesn't even require tools — the included wingnuts make it easy to secure the bracket to the mirror. To prevent cable damage, a 3" cable protector comes with the bracket. For extra security, adhesive pads for the XMicro and SIR-Mini antennas are included. Warranty: 1 year.
