    This is a UK idea that Rohn looked at several years ago. I don't remember 
if it'll handle EHS but hams will NEVER use this system because you need to 
buy the terminations and a special tool.

    6061-T6 has a yield strength of 35,000 psi. The figure is for the 
material so the particular configuration has little to do with it.
