As an example on 3.8 MHz: 66 ft of #14 AWG wire, fed in the center, 30 ft
high above average ground Er = 13 Sigma = 5 mS/m. Radiation efficiency
96%. Fed with 50 ft of 600 ohm open wire line: input impedance = 748 +
j2087 maximum voltage at feedpoint, with 1.5 kW input, 3.05 kV. Series
C, shunt L tuner, with inductor loaded Q of 200. Tuner Loss = 0.24 dB.

Forgot to mention. The transmission line loss is about 0.2 dB.
