You should be able to use the hard line as long as you seal up the hole to keep 
any additional moisture out. Also you should repair the outer shield, preferably
with copper so you do not have RF leaking from that spot. A good way to do that 
is to cut a patch piece from similar hard line so you can match the ridges on 
the outer conductor. Place that over the hole and cover it with coax seal and a 
couple of layers of electrical tape.

I have done this on hard line up to 6 inches in diameter and it usually works 
fine, but check it with a dummy load and an SWR meter if you have one.

Good Luck with the line.

ends. When it was taken down from a tower last summer, I found a pencil-end
sized hole in it, and a sort of splice where ground strap was attached to
the shield and run to the tower. The cable's in good shape otherwise. I set
it out in the summer sun for several days to heat the cable and (hopefully)
purge any moisture that might have gotten in the puncture.  

Any problem with patching the hole and using this on my next tower
installation?
