BUT IMO if the guys have little or no tension on them, then they don't
add appreciably to the compression on the legs but some of the wind forces
are transferred from the legs to the guy wires which is the purpose of the
guys. Guys in this case are more tethers than guys; that is, they limit
the forces on the legs without adding much to the total leg load.
Working along the "tether" angle... The guys might also help with
restricting the potential "fall zone" of a failed tower. With the guys
of sufficient strength, the tower isn't going to fall over and lay out
full length. That might help (if if not strictly defensible in an
engineering sense) in a permitting process.
This is like the cables used to hold lighting fixtures above the
audience. If the mounting fails for some reason, the light doesn't come
crashing down on someone's head.
