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.

Time to pour concrete. The concrete truck can only reach one guy station, so a motorized wheel barrel is used to transport 8 yards of concrete into the main tower and guy station holes.

Trenching between the tower base and the ham shack entrance. The picture doesn't really show the 18% downslope here, and the trencher was stuck and rolling into one of the deck support posts. Come-alongs are keeping the trencher from taking out the deck post plus the tractor is extracting.

One of three ground tower ground rods. The are each connected to a tower leg with both a #4 solid copper wire (per NEC) PLUS a 1 1/2 inch low RF impedance copper strap. Once connections are made, the ground rod is then driven down so it is at least 6 inches below grade.
