Maxview twin socket diplexed AV faceplate.
Single cable entry to provide two RF coaxial sockets from a single cable input. So in normal use you would combine two inputs onto one cable, such as a TV aerial input and FM, or DAB or CCTV etc. You could just use the face plate as a splitter for a single signal if you like.
The sockets are labelled TV and FM, but you can use them for whatever you want.
Comes with two fixing screws and screw covers.
