[Moon-net] Fw: Feed choice OZ6OL

[Hans.J.Oldenborg]

Hello Thierry,

0.43  F/D er ok for septum feed , but read all information in W1GHZ 
antennabook on line and all your trouble will go away! you also find the 
papers for the 2006 EME  Conference there  With feed horn measurement also. 
look at the OK1DFC  home page
