This single isolated coaxial socket from British General can be used for TV or FM aerial connections. An isolated aerial connection is ideal for use where a communal dish or aerial is used such as in a block of flats. The isolated socket stops interference from receivers (TVs, Digi boxes and SKY boxes) from spoiling the signal that the rest of the users receive. This Screwless Flat plate black nickel finish socket has a screwless flat plate that clips on and off and sits flush against the wall, making it ideal for modern interiors.
