[SBE] hole in heliax

[Reynolds, Paul (CXR-San Antonio)]

I first suggest you drill about a 1/8" hole at the lowest point to see
if any water runs out.  If it does or doesn't, then plug the hole with
epoxy or the like, wrap it tightly and pressurize a little.  Try your
transmitter again slowly.  I would be curious as to the 'size' of the
hole if it's blow out, lightning hit or bullet sizes.  Don't forget to
also epoxy the 1/8" hole you drilled at the bottom !

Subject: [SBE] hole in heliax

We have two holes in the 3" (air) heliax run to our stand-by antenna.
The antenna is at the 500 foot level on our tower, the holes are about
six feet apart at about the 300 foot level.  Might have been lightning?
Might have blow out when we applied power on Friday for the first time
in months? .  The line had been holding pressure until last Friday, so,
I'm figuring it blew out.  

Wonder if we should just splice out twenty-five feet of heliax or if we
should, at considerably more expense, replace the entire run.

Or try the splice and see what happens?

I can send anyone a pair of pictures if you are interested.
