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 ========================================= All three of B,L & E forgot to determine ground resistivity and permittivity. That's hardly comprehensive! Do your predictions fit BL&E's measurements, or those of Sevick, for *any* assumed values of ground resistivity and permittivity? Also , please tell us more about the fan of 1.0m radials, on the ground, that will give ninety-several percent feedpoint efficiency. -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek |
