[TowerTalk] Yaesu G-800DXA rotor

[Gene Bigham]

OK, I have acquired the rotator, it looks smaller than the Alliance it replaces but is rated heavier duty.  My question is, I am having the top of my small Aluma Tower modified and repaired as it was broken in the storm with 90 MPH winds as well.  So, what is the mast size range of the G-800DXA.  And what is the mount mast size range with the optional lower mast mount?
I am considering having the fabricator/welder make a cage to house the rotator inside the tower.  The T-150 Aluma tower is too small to accommodate a rotator inside its small upper section, but while we have it down and the top section out for repair there is no reason we cannot fabricate an aluminum cage to house the rotator inside the top section, with a thrust bearing on the top plate.  This should further serve to beef up this new arrangement.
Measurements for the masts appreciated as the manual and literature list no sizes, and thoughts on the cage idea made as an integral part of the top section also welcomed.
