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.

Holes for guy station anchors are 6ft long,4 ft wide and 4 ft deep. Concrete blocks are used to hold the rebar cage up off the bottom 6 inches so they are embedded in concrete when poured. Painted lines indicate the level of concrete when poured.

Originally tried to lift rebar cage from a single point, but it caused the rebar cage to deform. A lifting frame was then built which pulled up vertical instead of an angle.
