antenna, having a pre-amplifier built into it that's powered by a bias voltage
applied on the antenna center conductor (power comes from the GTN). The
1.5 dB of loss is to keep the receiver in the GPS unit from being over-driven
and thus degrading the signal.
What's the long term impact from an antenna lead that's too short?
I have a GTN625 which has been operating for about 18 months with a 1.5' antenna
lead.
