[Elecraft] (K3) SWR Consistent - low or high power

[Randy Farmer]

My example assumes a worst case of 0 dB return loss at all harmonic 
frequencies (i.e., the harmonic energy is all reflected). Any radiation 
or other loss mechanism at the harmonic frequencies will just decrease 
their reflected power and lessen their contribution to the total 
broadband reflected power seen by the meter. The real situation is even 
more complicated, as the directivity of the wattmeter coupler as a 
function of frequency must also be taken into account to determine the 
actual indicated VSWR.

Also, I should have said in the original post "... your antenna would 
have a VSWR of 1.07 AT THE FUNDAMENTAL FREQUENCY."

73...
