2 sets of steps on my AB-105 tower. This will allow for about a 4' piece
of mast held about 10-12" from the tower.

about 100 degrees or so of azimuth. Together with the 180 feature of the
SteppIR it should do the trick for JA/CA mults and for keeping the US off my
QRG when I've got the big boys pointed at EU.
You can either use one of the Hy-Gain mast clamps (there's one
for the Ham IV and a huskier one for the T2X) for mast mounting or fabricate
a flat plate.
You just install the angle iron on the leg and let it form an X.
Mount the flat plate on the X and you're good to go. You might need two X's
for mast pipe mounting or just two pieces of angle sticking out using
U-bolts to hold the pipe to the angle. You can do just about anything with
some
angle, some pipe and some U-bolts.
