Just wanted to be sure that the 45 degree idea and its potential big pitfall is
fully understood. I might have even tried it many years ago ;)..
One thing I did do for a few years many years ago was to put an Alliance U-110
rotator on the antenna boom of a CC 3219. Was only about 15 seconds to switch
polarities using that approach. Worked quite well. Since then have only had
longer boom antennas with required bracing that didn't lend themselves to doing
that anymore.

You are
correct. But since there are only a couple dozen FM
contesters spread across the country its a small risk. Its a
bad idea for an ssb station. If it becomes a trend, as
you ppint out, its self defeating. The reason for doing it
was to try and catch a big staftion 3 or 4 grids away on the
second day. No joy on that account for me, but as far as I
can tell it didnt hurt of course I will never know what I
did not hear.

Better think
the 45 degree polarization thing through a bit more. It only
works good if you are the only one doing it. If everyone
else is also turned 45 degrees in the same direction as you
are, and they are then pointed towards you, you will then
discover that the 45 degree polarization idea has a major
flaw.

Sean,
I cant take
complete credit for the idea. It
was one
of many ideas people on the reflector discussed wit
me last spring. I can say the loss wasnt
noticable. Not
only did I get my longest
range qso at 45 deg polarization,
I also
got my texhnically weakest, a 5w ht at 90 miles and
he was deep in an urban jungle.

John,
That's a pretty
good idea.
I was trying to think what I
would tell a new contester with
only FM
gear. As a primarily sideband station we run all
h-pol, and it doesn't make sense to change
that on our
end. Running your FM beams at
45 degrees if that's all
you got, if
possible, is likely the best of both worlds.
Canting a vertical might work if they are
broadside to the
cant as well, though
you're likely to add too many other
variables in that.
I thought I sent this email forever ago,
and
apparently it was just sitting in my
drafts. Oops.

Sean
& Zack,
For September
I was at 4400
ft ASL. I ran VV on Saturday and then set
the beams at 45 degrees for Sunday. At 45 degrees you
lose
3dB against a VV and HH station. The
idea was that an SSB
HH station (stacked
beams and amps) might just see me on the
band scope and flip to FM (seeing my freq was 146.520)
and
try for a QSO. Multipliers are hard
to come by on FM. I
didnt get any
"big stations" running HH. K8GP/R
was my only "high end" station and
they did run VV
for FM. Honestly I did
not notice the 3dB loss and set at
45
degrees I got my longest range FM QSO at 187 miles, clear
as a bell and I was working the side of his
beam.
