[aprssig] mobile antenna for D7?

I also have a dual-band glass mount (Larsen 2/70) at the bottom of the glass 
area on a hatchback type car (Acura Integra).  It works well with my 
dual-band mobile rig, but I do notice that the radiation pattern is not 
circular.  There is a definite preference to the back of the car.  This is 
likely caused either by the better ground plane to the back, or the fact 
that it is shooting through the bulk of the car towards the front.  But, 
with garage heights as they are, there is no alternative, and any antenna is 
far far better than none.

I use a glass-mount dual band antenna with good success. It's actually 
mounted near the bottom of the window, to keep the top of the antenna below 
the 6'4" height of the garage I park in at work.
