WA7DUH And WB7CNV Tower Construction

Photo essay of tower project at the station of Linda WB7CNV and Steve WA7DUH. They live just outside of the Richland and West Richland city limits in Benton County. Project is to initially erect a 65 ft guyed tower, but to design it for 75 ft or higher. Benton County has an ordinance controlling "communications facilities" (BCC 11.65) which includes "communication towers and antennas." Many of the requirements are exempted for amateur radio towers and antennas not exceeding 65 ft.

Peter Rosenberg (AC7SB) from Fall City WA joins the antenna assembly team. Steve (WA7DUH), Peter and Gary (W7TYQ) apply anti-sieze compound to the staddles that will be used for one of the Return Element fixtures. Liberal use of anti-sieze compound is critical because of the many dissimilar metals used in both the antenna and hazer (aluminum, stainless steel hardware and galvanized steel.)

It looks like coax in this picture, but it is Phillystran, a non-conductive arimid fiber guy wire. Good for about 4,000 lbs pull.
