Reg Edwards wrote: You've been reading books and magazines about rules-of-thumb written by old-wives. At 3.62 MHz and a radial length of 16 metres the attenuation approaches 100 decibels. So there's no current flowing in the radials beyond 5 metres. You can remove the excess 12 metres. They are not doing anything. What small current density there is beyond 5 metres is all flowing in the soil. The cross-sectional area of the soil carries the small current just as well as the radials. How did you verify your program Reg? I can go outside right now and measure current in a 40 meter vertical radial system, and 100 feet from the base there is significant radial current. Your programs results also dramatically disagree with Brown, Lewis, and Epstein's data in one of the most comprehensive radial studies ever done. 73 tom |
