OK - sorry if I get the gender of the sockets the wrong way round but to try and prevent confusion in others I believe I am correct in thinking the normal socket for the TV arial is female on both the TV & the wall plate - (ie you have a connection with a male end on both ends) Moved into a new property - in the lounge there is a plate with a total of 5 connections: 1) F-connecter marked Sat 1 2) F-connecter marked Sat 2/Return 3) Female socket marked Radio 4) Male connector marked TV 5) Female Connector - no label Given the above I assumed that I needed to connect the TV arial cable from socket (5) into the back of my TV as this would give the 'correct'/normal alighment on gender on the cable (ie both the same) and that socket (4) would be to distribute the output from the likes of Sky arround the property. I duely connected my sky box (works fine in digital) in this manner and got VERY poor picture on both my lounge set (watching analogue) and the other sockets (bedroom/ kitchen/ dinning room - i dont have this many TVs but just tested all the sockets). I therefore tested switching my connections in sockets (4) & (5) - which results in a female to male cable being used to connect the TV to the ariel and this gave a perfect analogue picture in the Lounge but still a very poor picture in the other rooms. Anyone have any idea what socket (5) is then? Why do I get such poor picture in the other rooms? It is newly built block of flats with shared dish etc for your information. The other quandery which may or may not be related.... in the store cupboard there is a gray plastic box mounted on the wall with a small circular grill and a blue light shining out of it. On one side there is a single black mid thickness cable going in and 4 equal sized cables going in on the other side. There is a fuse switch directly underneath which turns the blue light on and off but doesnt seem to do anything else which I can see in the property - seems a lot of cables for a small blue light.
