Rick,
that is a good antenna for 160 meters. I was thinking in terms of a 180
degree dipole terminated into 50 ohms. Like we use for EMC measurements. To
"calibrate" one of these in NEC I radiate it from a resonant dipole placed 100
wavelengths away. Then some calculations and we we end up with a very accurate
AF
(Antenna Factor). In fact, once the AF is figured for one frequency all other
frequencies are just a matter of calculation based on 20LOG(F/f). I forget the
exact frequency, but an AF of 0 dB occurs at about 35 MHz. Based on this, the
AF at 350 MHz is 20 dB. The signal at the antenna terminal is equal to the
E-field in V/m minus 20 dB.
