I tried using a lawn edger, but the problem was dirt falling back, and flung back by the edger blade, and filling in the slit before I could push the wire in. I finally gave up in frustration and fabricated a home-made plough patterned after the big ones the phone company uses to bury telephone wire, and that professionals use to lay radials for broadcast stations. It has a sharp leading edge that cuts the slit, and a tube brazed to the rear edge that lays the wire, all in one operation. I cut the pieces out of scrap metal I had lying around, and took it to a welding shop and let them assemble it. I attached it to a heavy duty Troy-Built rear-tine garden tiller I borrowed, with the tines temporarily removed, and with an assistant, laid 16,000 feet of #12 soft drawn copper in four days. 120 quarter-wave radials for 160. It would have taken me months of daily work to have buried them by hand using a spade.
