I believe Part 15 specifies the limit of a "10-foot"
antenna, and 100mW of power to the "final".

Not any more. Current Part 15 rules mandate a particular emitted field
strength at some distance from the transmitter.

It's all academic, however, since the FCC does not enforce part 15 rules,
and you can buy FM transmitters that exceed the limits at any department
store now.
