Only in students homework.

So what speed do your measurements indicate for
free electrons on an antenna?

You assume: "The value for conduction electrons / m^3 matched the number of
atoms / m^3, within the error of the copper's density"

It is not true. So the speed for steady current is bigger.
But in antennas is oscillating current. To describe the electrons one must
take into account acceleratin and compressibility. Speed at small movements
can be small but acceleration huge.
