What has feeding an antenna at the current node got to do with feed
line length?

Feedline length for an average system may be about 75 ft.,
the distance from the antenna to the transceiver. If a
current maximum point occurs at 87 ft., make the feedline
87 ft. long with (usually) no tuner required.

I assume what Fred thinks sucks is your implication that the
average ham feeds his antenna with 100 meters of feedline.
What percentage of hams do you think actually use 100 meters
of transmission line?
