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.

The tower base hole. 2x4's above the forms hold up and align the top rebar grid. There is also lower grid sitting on concrete blocks. The tower base that will be submerged in concrete floats in the center of both the top and bottom rebar grids. Temporary guy ropes hold the tower in perfect plumb. Grandson Adam approves.

The break wasn't so bad. The mess was created when the sprinkler controller decided to turn the water on, washed out the far bank and filled the hole. Duhhhh.

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.
