This document is to serve as a guide for sizing and purchasing the 55G tower. Tower and foundation installations should be performed by qualified and experienced personnel using assembly drawings provided with each tower.

DESIGN NOTES:

1. Tower designs are in accordance with ANSI/TIA-222-F and ANSI/TIA-222-G, Class I Structures, Topographic Category 1. 2. Design assumes towers are installed on level ground. Lower EPA values will apply for roof mounted towers or for sites located on unusual terrain. 3. Designs assume two 1/2” diameter lines on each tower face. 4. Anchor radius is from tower base to intersection of anchor rod with ground. 5. Guy chord lengths shown are based on level ground. Initial tensions for guys are shown in ( ) in pounds at 60º Fahrenheit. 6. Antenna and mounts are assumed symmetrically placed at the tower top.

PARTS LIST NOTES:

1. Items listed are required for complete guyed towers. 2. Base and anchor foundations listed refer to standard foundation designations. 3. Guys provided with each standard tower are based on level ground conditions with an additional 6% length. 4. Rev G anchor grounding (AGK1GGX) and base grounding (BGK2GGX) are included with the tower material. 5. Assembly drawings and a safety package (P/N: ACWS) are included with each tower. 6. Parts lists are subject to change based on availability or revised design criteria.
