Translator station

Definition
A translator station is a Low-power television station that retransmits programming from a primary station, such as a major television network (ABC, CBS, FOX, or NBC) or its affiliate, to audiences unable to receive the signal directly from the primary station, usually because of distance or terrain barriers (mountains) that limit the signal's ability to travel long distances. FCC rules prohibit translator stations from originating any programming.
