Hi Rob
I see copper prices have doubled in the last year.
My intention is to compare and contrast the cost and performance of short
verticals over a large field of ground radials v the very modest amount of wire
required for the FCP. In Guy's article
This is a false dichotomy between FCP and a broadcast station ground
screen. The best use of wire is to have a small number of elevated
tuned radials with proper RF choking. As shown by N6LF, you can do well
with just 8 radials, about 100 feet long each. On 160 meters, they
should be 20 feet high for optimum performance. BTW, cheap aluminum
electric fence wire works perfectly for elevated radials Also consider
N6BT's single spiral radial configuration as an alternative to FCP.
