Actually, you brought up the subject. :-) The feedline's power transfer
efficiency is just as important as the antenna's radiating efficiency.

Cecil, you forgot the efficiency of the PA DC power supply. There's much
more energy wasted there than what's lost in the feeder.

My DC power supply is a 12 VDC marine battery charged by a solar
panel. What's the efficiency of free energy? :-)

Sort out your power budget. ;o)

Actually, I don't much care about the efficiency of the electronics.
60 Hz energy is cheap. I am much more interested in getting the
generated RF into the Æther.

Cec, Good, now we're back on track. But what's the 377 ohms of nothingness
to do with a random length of wire which has any impedance you fancy just by
connecting to it. Even without making a connection and just using your
imagination. Could the person who confidently raised this subject from the
dead please give us some clues about calculating the turns ratio. I don't
have ready access to the works of Maxwell and there's no mention of it in my
1992 edition of the ARRL Handbook.

And I think my smiley is better than yours!

I think you have to measure the diameter of free space first, before
you can calculate the turns ratio.

Do write, when you get to the far side, and let us know how the
weather is, OK? ;-)
