Easter Compton is a relay of Mendip, serving the village of Easter Compton itself (near Bristol) plus some other small communities surrounding it bordering the Severn estuary, and also areas of Avonmouth, a large industrial and docks facility on the Bristol channel. The relay was necessary as the signal from Mendip is obscured by nearby Spaniorum Hill.

Prior to the construction of the relay, people could point their aerials across the Severn estuary to South Wales (Wenvoe). Easter Compton allows viewers in the area to watch English rather than Welsh region programmes
