Hi Zeno

Some will say it don't affect it all, others will say it will affect
it a little bit and other will say it affects it alot.

I had several little 1/16th watt neon lights laying around doing
nothing. I would toy with them, lining them on dipoles to find the
highest area of RF on the dipoles, once found, I would solder these
little rascals to the dipole so they wouldn't move in the wind.

Besides looking cute, they offered a little bit of help too.
When it was raining, they wouldn't lite at all on a couple of
antennas, and on others were very dim.
This alone tells me that there is some affect of rain on the antennas.

But one question has always perplexed me to no end.
Why will the light light up if placed on the end of my 10 meter mobile
antenna, but not on the end of 10 meter ground plane. It lights up
just fine about 19 inches below the top on the ground plane and about
22 inches below the top on a vertical with an underground radial bed.
