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. 73 Bob W7LRD

In addition to being easier for my practically non-existent construction abilities, I think the strip of brass or copper might be more forgiving, too. It worked for my VE3NPC helix http://n0jy.org/Antennas.aspx http://n0jy.org/images/L%20Band%20Array-2.ppt but given my abilities, I'm not sure how!
