OK, thanks everyone for the education. This came up because I wanted to build an RF detector to use with a multimeter as an RF field strength meter to compare different ground/counterpoise schemes for HF on a boat.
I ended up copying the circuit for the MFJ-802 field strength meter, which puts a load of 1 meg across a 1n270 diode bridge. Using a .3 volt drop assumption for those diodes gives a very linear correlation of voltage versus transmitted power in the near field. So the .15 volt assumption in the dummy load calc was a puzzle to me.
