    Unless these are VERY strong carbon steel tubes, I would strongly
recommend using I-beam (eye-beam) as it is much stronger than a round pipe
(tube). Are you going to get them engineered? Are you getting a permit (with
PE drawings)?

      Is the cable EHS? Rohn specs for 25G DO NOT call for 1/4 inch EHS guys
but do spec 3/16 inch EHS. Since the leg strength is the limiting factor on
25G loading, I would suggest not using the 1/4 inch cable.

     Your message stopped here for some reason.
