The best way to answer these questions is to get a copy of HFTA, which comes with the ARRL Antenna book. It lets you model the pattern of stacked antennas, varying spacing, etc., and factoring in you
Consideration of stacking distance on the boom length comes about from trying to maximize free space gain by minimizing interactions when using a yagi design that has fixed element lengths and spacin
You are correct. The program uses the number of elements as a surrogate for the boom length. It assume "traditional boom lengths for the number of elements. I have a 4 element 20 meter beam on a 54 b
Is it? There's two factors at work in stacking: 1) the interaction between the antennas and 2) the pattern of a single antenna. Boom length has an effect on this, but so does the particular design fo
I've done a fair amount of modeling for my 3-stack of 4-el SteppIRs (only the top one is in the air so far -- the rest will be mounted when the snow melts.) I think you're theory is correct, but may
