o.uk...
I have one last question.

I an using a home made tilt over mast made up of aluminium scaffold tube
( 2" OD heavy duty) and the same tube for the stub mast. I have two heavy
duty brackets made up that clamp onto the scaffold tube to hold the
rotator and support bearing in place.

What would be a good average distance to have between the brackets that
hold the rotator and bearing?

Thanks

I don't have any idea. I just put my rotator mounting plate where it fit
the bracing in the tower. That put about 5 or 6 feet of a 21 foot piece of
2 inch OD ( 1 1/2 trade size of galvinised pipe. I just based that on
where the plate fit and having enough pipe in the tower were I can pull the
rotator out if it needs repair.
