A friend has had poor TV reception and on checking, I found that the Aerial wall socket was giving a poor connection. The outlet needs to be replaced and I'm assuming that it was the original outlet.
The outlet fits a standard pattress box and has a single socket. The plate on the back of the outlet has two isolated connections and a coaxial cable going to each of them. I can't remember exactly what was on the plate, but there appeared ot be one or more capacitors.
The outlet is on a community aerial in a block of 26 flats.
I'm not sure what the cables are:
1) the outlet is in series with other flats an (I assume this to be unlikely)2) the incoming cables are one for TV and one for FM and the outlet is actually a splitter.
He has always had the TV aerial lead connected direct to the outlet socket and has generally had a reasonable picture, even getting freeview OK most of the time.
The only information I can find is YOD I/II printed on the plate, which leads me to assume that this is indeed a diplexer (In which case the socket is a combined outlet and he should have also been using an external diplexer to split the signal back to TV and FM outputs.
Can anybody confirm what the outlet is and what a suitable replacement would be?
Thanks
