Yuri, I don't know what you are going to prove. W8JI's
and W7EL's own measurements prove beyond any doubt that
the current at each end of the coil is NOT equal. And
the error they made in trying to measure phase using
a signal with unchanging phase is more than obvious.

What you are going to find is that the coil warps the
current profile away from a pure cosine wave as is
shown in Figure 3 at:

The delay through that coil is obviously NOT zero and
the currents at the ends are obviously NOT equal.
