MEASURE or FEEL it! Or disprove what W5DXP is saying.

This is easy to see using EZNEC. Model a 102' G5RV on 20m
and look at the current distribution. There are three
current maximums and four current minimums. If you install
a loading coil at a current maximum or current minimum, the
current magnitude will be the same on both sides of the coil.

If you install a loading coil at a point where the slope of
the current is negative (decreasing), the current at the bottom
of the coil will be greater than the current at the top of the
coil. This is the usual case for mobile antennas.

If you install a loading coil at a point where the slope of
the current is positive (increasing), the current at the bottom
of the coil will be less than the current at the top of the
coil.

Note: 'Top' of coil is the end closest to the the ends of the
antenna. 'Bottom' of coil is the end closest to the feedpoint.
