I wonder is any methods to estimate theoretically groung loss resistance of transmitting LF antenna (T-antenna with wire conterpoints mainly but others antennas also). I have good expirience in theoretical physics but I do not know, how solve the problem correctly...:-( My attempt to use EZNEC-2 was unsucsesfull. I get loss resistance about 1 Ohm. I know, that really ground loss is much more... Any coments, please! 73 de RA9MB/Alex http://www.qsl.net/ra9mb
