I used a "tab matching" method taught to me by Joe, K0VTY. Just a strip of copper following the first 90* of the helix. Adjust the distance to the wire for min. SWR. This was for L band antennas. Miss L & S stuff on satellites, and, you know.

In addition to being easier for my practically non-existent construction 
abilities, I think the strip of brass or copper might be more forgiving, 
It worked for my VE3NPC helix 
but given my abilities, I'm not sure how!
