Thanks for all the replys and helpful information.  Happily, I have 7 
zig-zags, so I have 25G and I got a great deal even if a little cold 
galvanizing paint is needed.  Sounds like the top section could use replacing 
for something which accepts 2" OD mast, but I figure 1 7/8" will do with the 
bushing punched out of the top section I have.

Does the mast really need to be something super duper like chrome moly 
galvanized this and that I have seen here and there?  Wouldn't some 
galvanized pipe (like plumbing, thick wall) work fine for just one antenna 
(ATB-34)?  Wondering about that.

Will have to buy a rotor plate (or make one).  How far down would be 
recommended mounting? (this would determine the mast length to some extent)

Also, is a thrust bearing a must have for an antenna this size and an HD-73 
rotor?  If so, does that go on a second plate above the rotor plate, but 
below the top section mast tube?  Wondering about how to locate this all, I 
could ness up if left to my own judgement!

Thanks again and 73,

Bob, WA2T
