how the heck can the lumped circuit model tell you that?


Wim, I forgot to note that using your stated methods, W8JI "measured"
a 3ns delay through a 10" long, 2" diameter, 100 turn, 100uh, 80m
mobile loading coil. Doesn't a 4 MHz RF wave traveling the length of a
large 100uH air-core 80m loading coil in 3 ns give you some pause for
reconsidering your methods? Every wonder why computer manufacturers
don't install 100uh coils in series with their computer bus lines to
speed up their computers? :-)
