I would think the tip is the antenna, but I wonder if it really makes
much of a difference. Especially if your active antenna isn't
connected to ground.

Thanks Bob,

The more I think of it, I'm sure I can check both contacts with my ohm
meter against the radio's whip antenna when I get ready to wire the
plug.

Best,

Good way to burn out the front end of your radio if it is not protected
against such things. (e.g. Sony ICF-2010)

Since no one has not answered it's the tip is the antenna and the ring
(outside) is ground. It's best if you use a short jumper of very flexible
coax (rg-174) from it as the stress from something hard (rg-58, rg-6), etc will
damage the radio.
