I recently installed a RS glass mount antenna on my '96 dodge
Intrepid. The area I chose was near the bottom of the rear window.

First problem. Higher, higher, higher! I have one for APRS, it is installed
as high as it can go on the side glass of the vehicle. It is also as far away
from the car radio antenna as is possible. Antenna is thus in the clear to
minimise interference.

The ONLY reason I used it is due to the dualband VHF/UHF on one side of the
rear hatch, and the screwdriver on the other side (ran out of mount space!).
The glass mount is a compromise antenna with lower efficiencies than a standard
1/4 or 5/8 wave deck mount.

That said, get a reinstall kit and mount it up as high as you can on the glass.
It WILL work, just not that great.
