Hello Sir George and Howard:

Anodizing the aluminum is kind of over kill as I have measured new
antennas and old antennas with 30 plus years of exposure to the
elements. No difference measured.

Interesting, as I have measured antennas with only 2 years exposure that
had .5 dB measured difference. A 432 MHz antenna scrubbed with a
ScotchBrite showed a .6 dB gain increase.

So B as in B, S as in S, as we say here in Minnesota.
