OK, I get the 1.414 term now. The RF is sampled at the voltage divider, and
the diode/capacitor circuit rests at the peak voltage it sees - which is
half what the transmitter is delivering. To get peak voltage of the RF
waveform at the input to the DL1, we multiply by two. To get the RMS we
then divide by 1.414. But 2/1.414 is 1.414, so we simply multiply the
voltage by 1.414.

Now for the 0.15 term....?
