Re: [amsat-bb] prime star dish

[Joe Leikhim <jleikhim@xxxxxxxxxxxx>]

I have that very same style dish and have been trying to figure the best
way to feed it from the past discussions on this group. The closest I
found was a "Channel Master 1 meter" dish described by W1GHZ (Appendix
5A) as having an f/D of 0.68. Can anyone suggest the number of turns
(and turns spacing) helical that would work best?
