The elevated radials need to be high enough off the ground so that the ground itself does not become part of the circuit. I go up a mast sections, about 4 feet. I don’t trust going much over 30’ with fiberglass mast, so I use 8 sections (32’). This is shorter than the 33’ vertical wire, so I tie it over to form an inverted V instead of a true vertical. With the vertical section roughly 2/3 of the length, the majority of the vertical polarization will be intact. I also add a guy ring at the bottom of the top section. To set up, stretch the vertical wire on the ground. Start telescoping mast sections together next to the wire. The bottom of the vertical wire should be about 6” above the bottom of the bottom mast section. Temporarily tape the wire there. Then stretch the wire along the mast and tape it to the top of the top section. Tie some wire to the lose end. Next pound a 3-4’ pipe half way into the ground where you want the vertical to be. The pipe is not really to support the mast, but to just keep the bottom from sliding. Fiberglass mast won’t tolerate much side stress without splitting, so you can’t just walk the mast up. Disassemble the bottom four sections. Place a section of mast over the pipe, then mount the two mast section with the wire over it. Pick up the 3 section mast up over the pipe and rest the bottom on the ground. Put another section of mast over the pipe and mount the 3 sections on top of it. Repeat until you have all the sections up. It helps to have two people, but I have done it by myself. Tape the wire to the mast every section or two. |
