In the course of my travels, I read about the K5GNA dish screening 
on K5OE's site:


According to the text you get 1.5dB from the screen.

As far as the 1.2GHz antenna, I've only got a couple responses.  
No real clear answer on whether linear or circular is an advantage, 
or if switching polarization is advantageous.  Not sure if this 
info is so common no one is interested in answering, or if there 
are so few users of the mode, no one really knows.  Nothing on the 
AMSAT site I could find.  Individual web pages on the topic yield 
a vastly disparate range of configurations, so no clear path to 
follow there.   I got a quantative value of 1kW ERP on 1.2 to work 
AO-51, and a source of yagi antennas from M2 and helix antennas 
from W7LRD.
