Gain is a function of boom length however you need enough parasitic
elements for the Yagi to work. The MonstIR DB42 has a boom length of 42.5
feet with four loop elements and two straight elements. This is the only
MonstIR that I see on the SteppIR site so I am guessing that this is the
antenna you are referring to. Are only the loop elements motorized? 4
elements on a 42.5 foot boom seem to be pretty big spacing for 20m and
higher. For example my homebrew 4el 20m OWA beam is pretty wide spaced
and it only has a 32 foot boom.

I have had a SteppIR (MonstIR, the big one like what they had at 6Y1V).
Instead I will just enjoy beating them in the
pileups since the 4 elements perform like 5.
