I am following with great interest the debate on our relative signals. G3YXM / G3XTZ ) As Dave said, my vertical is 20 meters high, but the two 10 meter loading wires from the top have to slope down at about 45 degrees ( to fit in the available space ). I have always thought that the effective loss of height was a price worth paying to avoid the need for a much higher value of loading inductance ( and loss ) at the base of the vertical. However, I am now FORCED into the position of HAVING to find a few more dBs of signal !!!! I would like to hear what others may think of the options: (1) eliminate the top capacity loading, and wind a bigger loading coil. ( 2 ) Fit a small, lightweight inductance at the top of the vertical and reduce the length of the capacity wires. ( 3 ) A combination of both. ( 4 ) Move. I would prefer the fourth option, since the local QRM here is curtailing activity severely, but it is also the most difficult ! 73's all, I will watch with interest for ideas, and I will conduct a test to try the effectiveness of the preferred one.
