Hi Bob,
I put up a used Cushcraft 10-4CD beam a little over a year ago. After getting
it assembled and before putting it up, I had it laying in the back yard. My
daughter's dog got it's line tangled up in the beam, and bent the reflector
back (away from the driven element) on one side. I straightened it up some
before putting it on the tower, but it's still noticeably bent. It seems to
work great, just as expected. From what I can tell there is no effect on the
pattern, as I get the expected results when I point it. SWR bandwidth is as
expected. So, I wouldn't worry about it. It should be fine.
Blair, NP2F
