Inspired by the recent article in QEX, I was just doing a bit of experimenting with NEC4 simulating portable verticals with severely restricted grounding systems. That is, say you put up a 30 odd foo
...snip... Jim, I have done some testing with radials, ground stakes, and the like here. The literature that discusses the topic at length echos your model's results regarding gain. Very little diffe
I've got a book here with some old G.H. Brown data. This is probably ~1 MHz data. It shows about a 6dB difference between 2 quarter-wave ground-mounted radials and 15 quarter-wave ground-mounted radi
There is a table in ON4UN's book, table 9.1 which I think addressed your interest. This is reproduuced from that book. 9-1 Resistance of buried radial systems radial # of radials length(lambda) 2 15
