My challenge to you was rhetorical. Based on past experience, I had no
real expectation that you'd be able to actually calculate a current.


Here's how to mask the effects that we have been discussing:

1. Choose a small inductance that replaces a very small number of
degrees of the antenna.

2. Use a ferrite coil designed to minimize distributed effects.

3. Mount the coil at a place in the antenna where the slope of the
current is virtually zero.

That's what you have done.

Here's how to showcase the effects that we have been discussing:

1. Chose a large inductance that replaces an appreciable number of
degrees of the antenna.

2. Use a typical air-core loading coil like a bugcatcher that has
appreciable distributed effects.

3. Mount the coil at the center of the antenna where the slope of
the current curve is near maximum.

When you perform your experiment with an 8 foot center-loaded
bugcatcher on 75m, then you will be taken seriously.
