[Antennas] Old Coax

Fri, 13 Sep 2002 04:44:25 +0000

I've got some in use that I know is well over 20 years old,
And it is still just fine. I us eit daily running QRP
and it works quite well.
On the other hand, I have had some that got so full of water
that the water actually migrated all the way into the shack
and leaked into a PL-259 on teh antenna switch.ON THE SECOND FLOOR!!!!!
Ya jest never kno!
