Transmitter power output (TPO) is the actual amount of power (in watts) of RF energy that a transmitter produces at its output. This is not the amount of power that a broadcast station reports as its ERP, such as "we're 100,000 watts of rock 'n' roll", but is in fact many times less for the high-power stations. The radio antenna's design "magnifies" the signal toward the horizon, creating gain. There is also some loss (negative gain) from the feedline, which reduces some of the TPO to the antenna by both resistance and by radiating a small part of the signal.

The basic equationAlgebra This article is about equations in mathematics. For equations in chemistry, see chemical equation. In mathematics, one often (not quite always) distinguishes between an identity which is an assertion that two expressions are equal regardless of th is: TPO × loss_feedline × gain_antenna = ERP

broadcast engineeringBroadcast engineering is the field of electrical engineering, and now to some extent computer engineering, which deals with radio and television broadcasting. Audio engineering is also a part of this. Broadcast engineering involves both the studio end and amateur radioAmateur radio commonly called ham radio , is a hobby enjoyed by many people throughout the world; as of 2004 about 3 million worldwide, 70,000 in Germany, 5,000 in Norway, 57,000 in Canada, and 700,000 in the USA. A holder of an Amateur Radio license has
