wrote My mother-in-law lives in a flat (sheltered accommodation) and until recently she had 1 aerial outlet plate with one aerial socket (female) as is most common. Due to them not having Sky I purchased the new top up TV box for her and went along to install it. In the recent past, a freeview box worked well and got all the muxes albeit with occasional break up on the mux that carries Sky. However someone has been into the flats and provided a new outlet plate with an F-connector presumably for Sky and two aerial out lets, 1 male, 1 female. Whoever did this, connected her equipment to the male socket via an adaptor and now two muxes have disappeared. Does anyone have any idea why two aerial connectors? If it helps, the flats are in Wombourne Staffordshire and are served (I suspect) by the Wreakin transmitter. One will be for FM/DAB radio. You will not get a TV signal out of it. -- Alan news2006 {at} amac {dot} f2s {dot} com |

Also, there may be some signal loss due to the diplexing process, which is a bugger, as I can't think of an answer for that, except to complain vigorously. Marky P |

There certainly is a standard: - for TV, outputs are male and inputs are female; - for radio, outputs are female and inputs are male. FWIW this is in EN 50083. If everything adhered to the standard, only male-female flyleads would be needed. In practice of course not everything does, and in any case the standard can't be applied to connectors handling multiple frequency bands. I have Diplexer face plates from two manufacturers one has a male connector for TV and the other a female connector for the TV. The latter of those is just wrong. Which manufacturer, OOI? -- Andy |

My Triax branded fully screened diplexer face-plate conforms to the above. I have Diplexer face plates from two manufacturers one has a male connector for TV and the other a female connector for the TV. The latter of those is just wrong. Which manufacturer, OOI? A diplexer from an unknown manufacturer, circa 5 years old , has female connectors for both FM and TV. If you look at the pictures for any of the diplexers/triplexers from Maplin you will see female for both TV and FM. If the OP had a fly-lead that previously fitted into a female socket and the face-plate has since been changed for one that has a male connector for the TV his existing fly-lead is possibly plugged into the FM/DAB radio output. Unfortunately the legend on some face-plates is raised white lettering on a white background so it may not be too obvious what each connector is for. -- Alan news2006 {at} amac {dot} f2s {dot} com |

If the imposition of female connectors on faceplates for TV is the result of some sort of European 'harmonisation' legislation, well, I would see that as yet another reason for sticking with our time-honoured convention. We use diplexed faceplates of all kinds. Some, unfortunately, have a male for the TV connection. This results in a large number of call-outs because people will always assume, quite understandably, that the female port is for TV. This is despite our explanatory leaflets, incidentally. In some cases by the way the second or third Belling provides a return feed to the bedroom(s). Bill |

Bill I would have thought if they were going to change things it would have been better to use 'F' connectors. |

Yes, but we also have problems with people who don't read the instructions regarding 'f' connectors which are in use for return feeds. This happens sometimes when the owner specifies a 'special finish' plate and we have to actually make the plates from blanks. Personally I'd have 'f' types for every connector. As you imply these are inherently better, and at least if all the connectors were the same the daft buggers would have to pause for thought. Or would they? http://www.wrightsaerials.tv/reference/0606.pdf might be of interest with regard to this discussion. Bill |

Well the current situation is a mess, really. Once upon a time all the fixed connectors were female, and all flyleads were male-male. Then along came VCRs and set-top boxes with male connectors on their loop-thro' outputs. These were made for markets wider than the UK alone and followed the convention that had become established in parts of Europe: male TV outlets. Then the input connectors on some FM tuners and receivers changed to male. There seemed to be an inevitable trend to a new order which, if it had been followed through to a conclusion, would eventually have made things easier for the non-technical user. We use diplexed faceplates of all kinds. Some, unfortunately, have a male for the TV connection. This results in a large number of call-outs because people will always assume, quite understandably, that the female port is for TV. Surely all the screened diplexed and triplexed outlets from the mainstream manufacturers are that way round (TV: male, radio: female, satellite: F)? It's in line with the new way and if people are given a chance to get used to it, it ought to be simpler: all flyleads would be male-female and problems due to wrong connections would become rarer. Return feed sockets, being TV /inputs/ are generally "right" - i.e. female. The trouble is the millions of existing single TV outlets and older-style unscreened TV-FM plates, together with the fact that the installation industry has shown no enthusiasm to adopt male as the sex of choice for single outlets (given that most of them will be used for TV). So I think the mess will continue for a long time yet, and clear labelling of outlets is the best thing you can do to avoid problems. Legislation to force a change to come in line with mainstream European practice here might actually be a good thing, but there isn't any. Technically a change to Type-F for everything would make a lot of sense, as it's a much better connector from almost every point of view, but I can't see it happening on consumer TV equipment for a long time yet or even ever. But you never know. Over the last few years almost all distribution equipment for use behind the outlet plate has gone over to F-type, regardless of frequency band, with no great drama at all. -- Andy |

At the moment Vision are doing both variations, although I think this is because they are changing to the foreign way. It's in line with the new way and if people are given a chance to get used to it, But why SHOULD people have to get used to it? It's change for change's sake. I can't believe the necessary uniformity for it to be worthwhile will ever arrive.

Legislation to force a change to come in line with mainstream European practice here might actually be a good thing, but there isn't any. No and we don't want it either. Legislation about TV outlets! Good grief! Don't you think we've got enough idiotic unenforcible unneccessary prodnose laws? The only justification would be if it led to full uniformity, but we all know that can't happen. TV wallplates last for 30 years. By 2036 the whole thing will no doubt have been superceded by who knows what. If you have a law about this you might just as well have a law saying . . . Oh God, every example of an incredibly stupid bit of comparible legislation I can think of is already in force! Bill |
