I just start out at the top with about 3', then 6' then 12', etc... give
or take. IE, I never have measured them. The top tier come away so
steep I doubt they have much effect. by the time they are of significant
lengthy they are well away from the antennas. Then again, I've not used
conductive guys in over a decade. OTOH I hang 160, 75, and 40 meter
slopers off the tower about 12 to 15 feet below the tribander and 30
feet below the 7L 6-meter Yagi.
