I am almost finished with a 16 turn helix for 1.2ghz. I am not sure of what type of matching I should use. Some of designs I have seen use a flat tab on the first 90 degrees of the helix. What size should it be? Is there a better way? I have a bird 43 with a 1.2 slug for tuning. 73 Bob W7LRD -- "if this were easy, everyone would be doing it"
