Antenna socket IEC is the standard antenna socket for use on TV. The IEC antenna connector is used on a wide range of TVs, SAT boxes, and cable TV boxes. The IEC antenna connector is available in male and a female version. The female socket is typically used when connecting to a wall socket and the male socket is used when connecting to the TV. In addition to the IEC male plug itself, we also carry a number of adapters that make it possible to combine the different plug types.
