[Antennas] Throug Glass Antenna information?

Thu, 25 Apr 2002 08:23:27 -0400

I'm using Larsen Through the Glass for a dual band (200 and 70 cm) with
a Garmin III+ GPS. With no problems!!!

The glass loss should be something around 0.5 +/- dB. This loss is
dielectric loss in the glass.

If you have RF in the vehicle you have another problem. [Broken coax,
antenna too close to GPS receiver, GPS poorly grounded, etc.]
