Gerry, I was flying blind, sort of speak, by the seat of my pants, building this vertical and pieced together things I had picked up discussing antennas with other hams so don't feel bad about not getting how it was assembled. I made the vertical antenna in two pieces in order to climb up to the roof on my tower bolted to the back of the house. The antenna was bolted to the other end of the roof so I could get right to it as needed for fine tuning. Right about roof level, the first section stuck up, therefore about a foot or two over the peak of the roof. The second section of antenna was made up of three parts. Two pieces of tubing, one short and one longer, and between the two was a coil form with wire wrapped around it. It was insulated wire and I used about three feet of PVC tubing as my coil form. The longer piece of tubing that served as the bottom of the assembly, I think it was 7 feet of aluminum tubing, I stuck up inside the bottom of the PVC pipe the wire was wound around, or coiled, around. It was wrapped closely, like a bull constrictor snake, because the wire, as I mentioned, was insulated and I was only running 100 watts. So that insured there would be no arking when transmitting. If you run higher levels of power, it is best to use coax, the heavier the better, based upon the power, because the voltage is very high on the coil when transmitting. Next, I took another 3 foot length of aluminum tubing and stuck it inside the top of the pvc pipe. The pvc pipe was big enough so I could drill into the tubing and the pvc pipe to hold the bottom tubing and the top tubing to the pipe or coil of wire. This is all vertical so far. The signal, therefore, had to pass through the coil before getting above the pvc pipe to the top hat, which was the difference between 32 and about 130 feet; which is a quarter wave on 160 meters. About 98 feet of coil wire in other words. The horizontal part of the top hat is also aluminum tubing whereby I used simple hardware clamps to clamp them in the shape of the letter X at the top of everything, that is, at the very tip of the tubing. The reason I made the whole top assembly separate, was so I could climb the roof, walk over to the vertical clamped to the end of the peak of the roof, and loosen another clamp which held the whole top assembly in place. Once I put the X on top, I didn't have to raise or lower the top assembly more than once or twice to get the antenna to resonate where I wanted it in the CW portion of 160 meters. It was fun making it, I learned a lot, and from that time on, when I put up a bigger tower that same year but in this house we bought that year, I really got into all kinds of wires and loops and shunt feeding my tower, and trying phased verticals and wire antennas.
