[amsat-bb] Polarization Switch

[Stefan Wagener]

Hi Jim,

That particular pol switch is mast mounted and pending your antennas will
allow you to switch polarization  horizontal, vertical, circular right,
circular left handed. As I said it depends on your antennas. The switch and
the additional phassing cables and the additional power splitter are
optimized for the X-Quad antennas WIMO is selling. Yes, they can also be
used for cross yagis if they are mounted in horizontal/vertical position
and you adjust the passing lines based on the plane offset. WIMO has the
instructions posted as part of the link you provided (underneath the pol
switch image. That will give you some ideas. They are written in German AND
English. Yes, for EME switching polarization between horizontal and
vertical linear polarization is preferrable, or polarization diverse
switching in 45degrees increments which is getting really fancy and cannot
be done with the WIMO setup as far as I know. If you need further
information on this switch, I have one (not in use at this point) and you
can contact me offline.

Hope this helps,

Stefan, VE4NSA
