Isn't this whole subject moot?

Hello,
I have been trying to follow this thread and gave up because the point is moot. If you are operating a 100 mW. tx at any height with almost any antenna it has been clearly shown on this board and in a recent thread about a FCC inspection that this will exceed the part15 FM limit by a vast factor. Why discuss hypothetical situations which do not exist in legal operations?
The frequent references to the Belkin units is interesting because if they are FCC certified it doesn't matter what output power they produce. They had to be certified as a unit including the antenna and obviously if the certification is correct for the Belkin units, they met the field strength requirements. The rules apply only to the field strength and not the tx power or the antenna. The radiated field depends on the power and the antenna and the Belkin specs. cannot be extrapolated to a 100 mW tx feeding a whip or dipole.
