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.

Distance between this driven element EHU and the element return fixture is critical. Houston, we have a problem. The driven element is centered on the mast, which means it will loop around the tower. This will cause great difficulty with the tower guy lines.

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.)

#4 solid copper over to the house electrical entrance ground. Found more irrigation, Spinkler valve control cable (run in water pipe PVC) and some Romex (indoor only) that the previous owner had run to some outdoor lights. Gotta fix all that.
