I am very new at ham radio and find myself confused over an installation of a Carolina windom 80 special.

I attatched a 20m run of coax to the line isolator. When I switch on the rig I get nothing, even on strong BC stations. I assumed it was a coax prob and striped my plugs down etc. I then discovered that if the shielding was not touching the socket on the rig I got a very good signal. So I assumed there was a short in the coax. I checked the plugs and they seem fine but I note that even when I have just the co-ax plugged in (ie no windom) I get a good signal unless the shielding is connected. (I guess that would make sense though I thought the shielding stopped the centre core picking up a signal.

So where is my problem? Is it the antenna? Is it the ine isolator. (There is no indicator which way round it goes so I presume it is universal.) I have no tset equipment as yet so an easy solution would be valuable.

An inexpensive volt-ohm meter, $10-20 American, would allow you to
test for shorts or continuity.

(Or maybe you could rig a flashlight to test for shorts.)

Most, if not all, Carolina windoms use a voltage balun and therfore
will show continuity between the coax's center conductor and shield.

I have done some tests and am happy with coax. So I am left with the
antenna.

I am sorry but the quoted comment means very little to me in my newbie
status.
