CHAPTER SEVEN: SELECTING & INSTALLING GUY WIRES C onsistent, safe support of antenna installations over 10 feet above the uppermost wall bracket or roof mount depend on how well the guy wires are installed. The correct installation procedure is relatively simple. However, only the best quality materials and careful installation will provide sturdy, safe, long-lasting support. Fig. 7-1. The materials and hardware needed for guying a standard three-wired guyed installation. Guy Wire Installation The materials needed for a standard guy wire installation are: guy wires, a guy ring(s), screw eye, and turnbuckles (Figure 7-1). Six-strand, 18 or 20 gauge galvanized steel guy wire is recommended for general use. (The 18 gauge wire is recommended for high-wind areas and installations over 20 ft. above the uppermost support.) Fig. 7-2. Channel Master Galvanized Steel Wire Model 9080. Standard antenna masts (10 feet in height) require only one set of three guy wires (Figure 7-3). Telescoping masts generally require 4 guy wires for each 10 foot section. This will give the extra strength required for most installations. 20 SELECTING & INSTALLING GUY WIRES Fig. 7-3.
