Part of the mechanical problem of this is that two back guys to the top of the vertical, and then the wire pulling away horizontal, exert a downward compression force on the vertical, to the tune of 20 or more pounds if there is a wind blowing. Visualize a bowling ball or two on top of the vertical. It can be done, but it's touchy and makes the vertical a lot more fragile than if only used as engineered. Designers were considering the only weight involved was the vertical itself.
