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.

Both the EHU and Element Return fixture must be leveled, then torqued to specifications.
