Th Dacron rope I use is a UV-resistant variety that may not be available locally. Places like www.radioworks.com sell it as "antenna rope" in a variety of sizes. I use the 3/16 inch black double-braided stuff, but 3/32 rope would probably have more than adequate strength for guying a PVC mast. Olive drab Nylon parachute cord may be more readily available, and is often used by hams as an antenna support. Lyle
