Re: Helix feed



if you are using the feed infront of a dish then it has to be wound
anti-clockwise. LHCP as when it reflects off the dish it becomes RHCP
if you are using it as a helical beam then it is wound clockwise for RHCP.
take a look at this web page for some info on homebrew feeds etc.

Or look at

hope this helps
cheers Mark

> Just so I get this right the first time, I've wound a helix and I'm ready
to solder it to a Type N feedthru.  Which end do I solder. This will be for
RHCP to receive AO40. From the solder end, should the helix winding be
clockwise toward the dish? Thanks, ron n6paa
