Mobile Antenna Expert needed

[Tom]

Hi George,
I am available pretty much anytime this weekend. I have a few things to
do on Saturday morning before noon, but other than that my time is open.
Let me know what is the best time for you and I'll put it in my
schedule.

the radio end of the antenna cable from whatever it is connected to, you
can then measure the electrical resistance between the point where the
antenna mounts to its base and the vehicle chassis with an ohm meter. It
should be 0 ohms.
