[Towertalk] Rotor And Aluminum Question

[kshaddri@xtratyme.com (Kelley Shaddrick)]

Howdy,

I've got a 20+ year old Telex CD-45-II rotor that I'm planning to put up on 
a tower during this summers antenna season. The rotor has been stored for a 
number of years. Is there any maintenance I should do to it before I stick 
it up 64 feet in the air? Does anything need to be greased, etc.?

Also, I'm looking for a source for 7/16 aluminum tubing to repair some end 
sections on a beam antenna. I don't need a lot, just 6 - 19" pieces. Anyone 
know where I can get something like this?

Thanks,

Kelley-W0RK
