Antenna System

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

Radio systems with the antenna(s) in the glass are subject to possible interference when an aftermarket window tint is applied.

Backglass Antenna (If Equipped)

The AM-FM antenna is on the backglass with the rear window defogger, at the top of the rear window.

Antenna Module (If Equipped)

The radio antenna is connected to the antenna module. The antenna module is powered by a battery voltage circuit supplied by the radio. The antenna module boosts the received signal and transmits the signal to the radio via a coaxial cable.

Fixed Mast Antenna (If Equipped)

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 its base. If tightening is required, tighten by hand, then with a wrench one quarter turn.

Multi-Band Antenna (If Equipped)

The multi-band antenna is located on the roof of the vehicle. This type of antenna may be used with the AM/FM radio, but is primarily for OnStar® and the XM™ Satellite Radio Service System, if the vehicle has these features. Keep this antenna clear of snow and ice build up for clear reception. If the vehicle has a sunroof, the performance of the system may be affected if the sunroof is open. Loading items onto the roof of the vehicle can interfere with the performance of the system, ensure the multi-band antenna is not obstructed.

Rear Side Window Antenna (If Equipped)

The AM-FM antenna is located in the passenger rear side windows. Make sure the inside surfaces of the rear side windows are not scratched and that the lines on the glass are not damaged. If the inside surfaces are damaged, they could interfere with radio reception.
