Using the other solid aluminum shield on discarded 3/4 inch CATV cable
end runs (called by some 750 or .750) spaced 24 to 36 inches from a
towers is a significant improvement over a single #8 wire. Yet a
skeleton cage around the tower and taped at or near the "sweet point" of
3 or 4 wires is even better.
