 ```I would go out to the same guy point with all guy levels. Its neater and less work. I'd go out 85% of the highest guy (39 feet x .85 = 33 feet) and attach all guy levels to your guy anchors located 33 feet away from the mast. Then, to determine guy rope length the formula will be the height of the guy point squared plus the distance away from the mast squared = the length of the guy rope for that level, squared. So if your first guy level is at 10 feet and the distance from the mast where your guy anchor is located is 33 feet away then: A2 + B2 = C2 (where the 2 means squared) (10x10) + (33x33) = C2 100 + 1089 = C2 1189 = C2 34.48 = C So the first level of guys should be cut 34.5 feet plus an amount for attaching the rope to the mast and guy anchor. Just my \$0.02 worth.

Alain, I forgot to mention that you could guy 30 ft. out from the base if you want. Also, if you buy dacron rope in 500 ft. spools one spool will make a complete set of guys for one mast. You still need a halyard. Finally, to figure the guy length it isthe square root of the height of the anchor squared plus the distance from the base to the anchor squared. I think that is what you intended to write. However I don't know how to make the formula in email. 73, Bill AI4WM Alain Michel wrote: Hello All! I am in the process of erecting a 40'+ mast to support the feedpoint of my G5RV. I was initially planning 3 wires [Dacron rope] at each level. Should I use 4? Using A2+B2=C2, how far out from the bottom of the mast should the guys be fastened to the ground? I plan on guying the mast at the 20', 30' and 39' levels. All suggestions will be most gratefully received! 73, Alan...KI6HPO --------------------------------- You rock.
