Hi guys,
I know but I'm talking about let's say 47/ 76 GHz bands
or DSN on 38 GHz.. Dish with 0,1deg for -3dB could
have a problem with JFL's solution, I'm just curious :-)

By the way I saw that Dan HB9CRQ is using 10m dish
for 10 GHz with main lobe 0,2dB for -3dB. I guess
it must be on the edge too.

""Hello Matej
It does not make sense to have better than 0.1 degrees resolution if the 
mechanical movement of the dish is higher than 0.1 degrees
