I am looking to install an antenna on my leased 2000 Jeep Grand Cherokee for the Yaesu FT-1500 that my fiancee is giving me for Christmas.  Since it's a lease, drilling holes is right out.  I would like to install one of the glass mount antennas on a rear (cargo area) window, but have heard from some folks that the deep-tinted rear windows (like I have) severely reduce the performance of glass mounts.  Has anybody had any experience in this area, and what glass-mounts seem to be the best.

I have the same hang-up with an Astro van, park in too many garages to fool with taking a mag-mount on and off or having to remember to take it down.  Maybe you could use a luggage rack mount.  

The Radiall/Larsen web site had a Q&A section with how to identify the markings on the auto glass to see if it would work with their Kulglass antenna.  The GM deep tinted glass on my van will not work.

Good luck and let me know what you find.

On-glass antennas do work. But you must pay attention to a few things. Number 1: a good ground at the antennais needed. In my case, a 2" wide, 4" long piece of copper foil above the headliner does the trick. Number 2: The capacitance added at the base of the antenna will make it electrically shorter. On my car the whip length is about 27" for quarter wave resonance. No, regardless what the advertisements say, this electrical quarter wave antenna does not have 3db "gain".
