A little deductive reasoning should resolve the issue.

It strikes me that the "flat earth" er, equal current society arguing that coil
MUST have the same current going in and out, must have a problem then with the
extreme case of coil - stretched wire, which must have even more "samer"
current at its ends. :-)
I like the statement on the cover of ARRL Antenna Book: "The ULTIMATE reference
for Amateur Radio antennas, transmission lines and propagation"
