I was "privileged" to be a witness to more "wisdom" from the antenna "guru"
W8JI at the Dayton Hamvention Antenna forum.
Based on his "unshakable" knowledge that current in the antenna loading coil is
constant, he proclaimed that it doesn't matter where the loading coil in the
antenna is, on the bottom, middle or close to the top.

I bet that includes a large capacity hat though. If he is using a
large hat, what he says is true. If he is not using a hat, it is not
true. And I'm sure he knows that. Any current taper through the coil
in itself, has little bearing on the best location of the coil and
performance. Taper, or no taper, it's location will greatly effect
efficiency when NO hat is used. No doubt about it. But, if you are
using a large hat, what he says is fairly true. The location of the
coil really doesn't matter near as much, because the current
distribution is fairly linear even with the coil at the base, middle
or top. There might be slight improvements by raising the coil on a
large hatted system, but it will be minor compared to the no-hat
version. MK
