It depends, if you have all day to sit and call you may work a DX station
thru a pile up on anything, but if the guy say I am going to work three more
stations then you might not, which is where the best antenna and station
come into play.
If you are working DX through a pile up the Steppir tends to get though. No
numbers or facts to support the claim, but it does the job.
Many times a DX station will say "you have Steppir", "they always have the
loudest signals on the band". Why do they bother to say that if they don't
think it from experience. My 3 element Steppir certainly works better than
my 3 element A3 Cushcraft, both have the about the same numbers on 20 meters
and should not even be a fraction of an S point difference at the DX end,
but there is a difference.

Am I going to work something on a SteppIR that I can't work on a LP? Or a
TH7?
Don't think so.
