There are no more watts emitting from the antenna. A 25 watt signal is still.25 watts, regardless of antenna design. Gain just indicates how that power is used.

That is true, but doesn’t matter.  The “effective” radiated power (ERP) is the product of the power input to the antenna, times the gain relative to a half-wave dipole.

Many folks, however, actually believe the actual watts increase. I was trying to clarify thar. I consider your answer above to be valid.
