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.

It looks like coax in this picture, but it is Phillystran, a non-conductive arimid fiber guy wire. Good for about 4,000 lbs pull.

Each of the 3 tower grounds are out abot 7 feet from each tower leg, with #4 solid copper and 1 1/2 inch copper strap back to the tower, over to the house electrical ground and down to the ham shack. Two inch rigid non-metal conduit is also buried in the trench to hold 4 runs of LMR-400 coax.

#4 solid copper over to the house electrical entrance ground. Found more irrigation, Spinkler valve control cable (run in water pipe PVC) and some Romex (indoor only) that the previous owner had run to some outdoor lights. Gotta fix all that.

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 #4 solid wire and the copper strap is also run to the house electrical ground and into the ham shack entrance.
