There is always an ongoing discussion about this in the SteppIR forum on
groups.io. The key to making the SteppIR antennas anything more than
pathetic on 6M is adding a fixed reflector. Some in the group have modeled
and developed 6M antennas on the same boom that rival commercial monobanders
on the same length using only the original driven element as being
adjustable.

That modification is by GM3SEK (about 2015). I believe is was in one of the
UK publications. In any case, Doug is correct, the modification adds both a
director and reflector turning the 3 element SteppIR into a proper four
element yagi on a 12.5 foot boom.
