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.

Here is the house ground rod as we found it. It doesn't meet code. Only one ground was found or wired into the electrical panel, but code requires two, with at least 6ft separating them. The solid copper wire is also too small, and the one rod was not 6 inches below grade. So we fixed that up.

The guy rods have 6 x 6 x 1/2 in steel plates to keep them from pulling out of the concrete guy station blocks. Picture shows drilling the 3/4 in holes for the rods. I need a slower turning drill press.
