Thanks Cecil,
the standing waves do it again!
See if you can get Tom to assert that the current into and
out of a coil in series with a transmission line with reflections
is also constant. :-) Same principles apply.
So far the best argument against W8JI's Kirchoffs and Ohms!
You can get a ballpark estimate of those currents by comparing
a 1/2WL dipole to a loading coil dipole. Assuming the following
two dipoles are resonant on the same frequency:
-----y----------x-----FP-----x----------y-----
-----coil-----FP-----coil-----
Assume the feedpoint impedances are the same and the losses in
the coils are negligible. The net current into the coil is close
to the current at 'x'. The net current out of the coil is close
to the current at 'y'.
