SteppIR.   I've got some 2" angle iron that  I'm going to bolt in place of 
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.
