You may fail to grasp it, too. When you hear about TV stations
(especially UHF stations) using millions of watts of power, they are
referring to ERP - Effective Radiated Power. That means the actual
power going into the antenna is much lower but the antenna has very
high gain. Rarely do stations use more than a few thousand watts of
actual power. The transmitter's actual power usage is a drop in the
bucket compared to all the other energy a TV station uses for lights,
cameras, HVAC, etc.
