[Mobile-Portable] Through the glass antenna on double pane windows

No, the way the thru the glass antennas work is have a capacitor formed 
by the two pieces of metal on the outside and inside of the glass.  When 
they work, they work, although some folks claim not very well. I had an 
old Avanti 2m antenna that moved on and off 4 separate cars and it was 
about as effective as a 5/8 wave mag mount in terms of hearing and 
getting out.  Think of the two pieces of metal as a variable capacitor 
that gets tuned by moving one of the pieces and you'll get how it works, 
with a resonant circuit as part of the antenna.

That's why I said experiment, if it works then you're in good shape. 
Incidentally I forgot to mention that there was a coil in most of the 
antennas to act as the rest of the tuned circuit too, I learned to move 
the pieces first for an approximate match on an 86 Toyota Tercel Wagon 
and how they were made later.
