Well, that's your answer. If Rohn doesn't know - no one on TT has any
better answer.

No. Having the anchors out 80% of the tower height is just ONE scenario -
there can be many; i.e. 50%, 100%, 120%, etc. But deviating very much would
necessitate doing the calcs for each scenario to ensure safety and
reliability.

Texas Towers and National Tower are long time Rohn dealers with
competitive prices. Also W7NI at Antronics is a good source.
