OH MY GOODNESS!!

In my discussion on Faraday rotation, I COMPLETELY forgot about the 
person using a linear polarized antenna.

HMMM!  I guess i forgot is because my very first 2 meter up-link antenna 
was a turnstile, actually on the ground.  The second was a linear yagi , 
mounted horizontally and I lived with the limitations.  The third was a 
pair of yagis,  one horizontal and one vertical.  I switched between 
them,  Then I made a phasing harness to make the two together be 
circularly polarized.  By the way,  all of this was "pointed" with a 
pair of the trusty Alliance Tena Rotators and the weirdest of all 
arrangements of gears, etc.

WELL, where does that leave me ??   Faraday is still right. Rotation Is 
going to happen and something has to be done to accommodate it to get 
maximum signals.

It's been good day, staying home and working satellites or changing HF 
bands  with propagation shifts to work FT8 or capturing data from AO-91, 
92, 95 with my Fox-in-a box.

Hope you all a having a good day!
