Re: UO-22 & KO-23




Hi Richard/amsat-bb:

When using a horizontally polarized yagi, I find the opposite is true (in
the norther hemisphere).  And nighttime passes are quite a bit weaker than
daytime passes.  I do not notice either of these effects on AO-16, LO-19,
or IO-26 with their "flaired out" canted turnstile 70-cm antennas.

This makes me think that the antennas on UO-22, KO-23, and KO-25 were
physically designed to favor vertical polarization.  (It's pretty rare
you'll see true circular polarization from a satellite, regardless of
the antenna on the spacecraft).  Using horizonal yagis with these birds
is a real challenge, at least for me. 

Just a thought, based on little more than superstition.  :-)
