[TowerTalk] Guying Alum Tower

[Kelly Taylor]

Given how much work and expense there might be in re-engineering the 50-foot Uni to 80-100 feet, are you maybe better off finding a use for the Uni at its design height and finding good, used Rohn for the 80-100 footer?

A guy is now advertising 7 sections of R45 plus a top section for $750. Can you do your extended Universal for significantly less than $750? Seems to me, given the safety issue and given the design specs of the Rohn, any cost-benefit analysis would have to significantly discount from that $750 to be worthwhile. 

73, kelly
