[TowerTalk] Rotator mast mount

[Guy Molinari]

Anyone have any recommendations for mounting a Ham IV atop a 2" mast section.    I'm building a standoff mount on one of my towers for a 3 element 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.   
 
Now I just need to track down a mount for the Ham IV.   I should get 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.
 
Any thoughts?
