I think I recall the Steppir people telling us that the max fwd gain vs lowest vswr may (probably?} occur at different element lengths. Perhaps someone (Steppir?) can tell us how much variance in gai

-- None. As long as you just change just the driven element length. The gain is quite broad (very little change clear across the 20 meter band.). The f/b is much sharper with frequency. I have the el

There is a SteppIR group on yahoo that you might also want to post the question to. Several nice, knowledgeable folks there as well. _________________________________________________________________

None. As long as you just change just the driven element length. I'd like to see your data, Rick. 73, Mike NF4L _______________________________________________ _______________________________________

Normally designing an antenna is a compromise between the SWR curve and the F/B and gain is basically a function of boom length. Since the SteppIR adjusts at various frequency increments, I would gue
