It depends on what goes on the mast but if not large I'd clamp the mast
between couple of 2 X 4s or 2 X 6s with through bolts and washers. I let it
tighten at an angle so one leg of the tower is also clamped between them.
Another route is to just take a 2" pieces of steel angle, drill and bolt it
to the rotator plate. Then using a "muffler clamp" that will fit the mast,
"U-bolt" it to the angle. Note, plain muffler clamps are uncoated steel and
rust rapidly. Saddle clamps work much better but cost a lot more. All are
far cheaper than using a commercial mast clamp.
I've used both methods sucessfully. Just don't expect them to keep a large
array from turning.
