In my design, you can make the changes to a steppir on a tower if you
can reach your passive 6M element. You don't have to order any
parts to make this work.
The GM3SEK modification can also be made "on the tower" as both the
new elements are less than 4 feet from the mast. Ian spent considerable
time modelling and working on an element mounting system to provide
stable operation with changing weather.

I added the 6M element and wasn't happy with the performance.
I remodelled it and I was able to improve a number of things and posted the
measurements on my QRZ page if you are interested.
Not only did it model better it performed better and loaded better as the
SWR was lower. A bunch of my friends tried it and they were pleased with
it as well.

This was for the 3EL Steppir.

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.
