40 METER VERTICAL
The 40 meter vertical is an old vhf mast I bought at radio shop in London it was in my garage for some time the mast is made up of number of aluminum poles making a telescopic mast, the length was 40 feet and held together with jubilee clips it diameter of bottom pole was 2.5" and top pole was 0.375" .One afternoon I got out of garage and start to put the mask together on our patio and realized I could not use this as a vhf mask but as a hf antenna I could adjust length to be resonance on 40meter as a 40meter 0.25l ground plane . At that time I just moved in to my present QTH, I wanted to mount the 40 meter vertical near to the oil tank I had an old telephone pole which was bough of BT I have dug a hole 4 feet deep to put pole in and cermets the pole I let the cement dry for about 2week this made sure that cement was well set we had have path made before I had the path laid I put some of that fence wire ( square holes ) from local hardware shop and laid under path this will be path of my ground system I adjust the length of pole to be 33 feet and 2 inches and by tiring the pole to telephone pole and use antenna analyzer to adjust the length of pole for resonance I found in local farm shop that sold large jubilee clips which was 6" diameter by use 2 clip connected end to end I could go round telephone pole and the antenna I use 12 jubilee clips to hold the antenna to pole
