Topband: 'the old ways...'

whatever happened to the 'old way' of measuring ground loss?

back in the 80's we would look up the predicted impedance from LaPort, then measure it as accurately as possible with a General Radio 1606..and figure the difference is 'ground loss'...

today, with better software ( EZNEC5 ), we can model our antennas over 'perfect ground', and with better hardware ( i like my VNWA2 ), measure with some confidence of reasonable accuracy. and again, figure the difference is 'ground loss'...

this at least gives you a clue what is happening, beyond 'just put out as many radials as you can, as long as you can make them'....in my case, with scant available real estate for radials, i come up with about 6 ohms of ground loss...

respectfully submitted...tell me why this is 'wrong'....73 w5xz, dan
