That must have been some storm, Barry -- I've never seen more than .2
variation in SWR on mine. I think F12 makes some lexan spacers that could
be useful -- contact Natan.

As for rain static, I've seen suggestions that grounding the ungrounded
half of the driven elements will help, but frankly I'm skeptical. My 40M
yagi has both sides grounded because of the hairpin match and it is still
noisy in certain rainstorms but not others -- when it's noisy, so are my
C-3s, and vice versa. Smetimes it can rain and blow like crazy and there's
no additional noise at all. G figure.
