Hi Dale,

Damn it!  You're 150% right!  Why the hell didn't I think of that?  Think of
all the labor I would have saved... easily 40%... well, maybe closer to
37=BD%... or is it 21.925%????? There's got to be someone out there with a
nomograph or an antenna modeling program who knows. Do the numbers change if
you're below the Equator?  Are stacked beams treated differently?  What
about wire antennas?  Verticals are ...of course...excepted.  You didn't
think THAT ONE would get past me...did you?

Whatever!  There's also the "big bucks" to be saved in Krylon... but keeping
the spray to the polished part of the elements can be very tricky with the
wind and all.  Probably does pay to spray paint the thing indoors anyway...
The vapors do interesting things to the few brain cells one has left.

Really enjoyed your post!  Thanks.  And don't forget to keep looking up and
keep smiling! (Didn't Jack Horkheimer of the Miami Space Transit Planetarium
say that on his PBS shows?)

Roger, K2JAS

PS... And I really thought no one on this reflector had a sense of humor...
I apologize guys!  You've restored my faith!  Put your hands on the radio...
say Ahmen!
