so are you using some kind of adapter to go from the SMA female connecter on
the radio itself to the connecter on the end of the coax of the antenna?
Or does the antenna coax have an SMA male on it already? I ask because you
can buy mag mounts with either an SMA male, or a pl259 connecter...anyway,
you'll have to determine what you have and the type of jumper cable you'll
need.

Thanks. This is good info. that is indeed the amplifier I=E2=80=99m =

on a high shelf near the window.
Thanks.
