Hector,

Where or when does an RF transmitter get it's leading power factor?  I
do not fully understand your position of RF always being leading vs unity.

For instance is an RF amp designed to have a different power factor than
an audio power amp or are they the same until the signal arrives at the
loading?

I don't see how the power factor becomes leading until loaded by the
capacitive load antenna therefore designing the most efficient feedline
the transmitter power amp should sit right at the antenna.
