A mini box, two jacks and a piece of wire. I doubt a schematic is necessary.

Yes I know there is a yahoo group for them before someone provides the

;-) I plug and unplug my external antenna quite often (as should
everyone.) My
question and worry is that over a period of time it will do damage to the
entrance of the radio.

Is there an adapter at Rat Shack that I can plug my external antenna into.
Follow me? One that I can just leave plugged into all the time, then
plug
'into' when I'm ready to listen?

Hope this makes sense. ;-)
