Default Request EZNEC computation

I think I need to just haul my Wattmeter up to the feedpoint and
measure the loss for myself!


Hi Ed,

That won't fully demonstrate the magnitude of the problem either. The
Wattmeter will only be calibrated into a matched load and if you
provide the matched load, then you won't suffer the Mismatch Loss
(where the drama of this soap opera resides).

You will then be back into a technical discussion complete with loss
multipliers or transmission line mechanics that will act as a narcotic
to your audience. If you supply the mismatch then you are going to
have to juggle the forward and reverse powers (and explain why forward
isn't as high coming out as it is going in the line).

The result is the appearance of a game of three card Monte .

You may as well treat them like full-fledged technicians and lay out
the entire problem from the beginning with a technical solution at the
end.
