I read in sci.electronics.design that gwhite wrote
(in ) about '1/4 vs 1/2 wavelength
antenna', on Fri, 25 Feb 2005:

I'm sorry, but they are not. Nor are any power amps that I know of.
Efficiency (and thus necessarily output swing) is what matters for power
amps. To maximize swing requires load line matching, not impedance
matching.

What is a 'load line'? A straight line on an I/V graph? What does the
gradient of that line represent?
