I can't comment on the Steppir dipole but I have an old KLM 40 meter rotary
dipole at 50 feet with a big airwound coax balun at feedpoint and it makes
the difference between no or hard copy and easy copy on many many signals
both stateside and DX . The deep nulls off end really help in my noisy
location , especially a neighbor with a 5KW horizontal oscillator in
whatever he is using .
Turns out its not too shabby on 17 meters either .
I was quite surprised when I put it up , was not expecting that much change
as it was rotated.
