Jerry Smith: Completely apart from the advice given by MikeP as far as your various options are concerned and purely centring on the dish, how many coax cables can you see connected to the underside of the dishes LNB?
And with regards to the connection points in the other rooms, are these screwed type male "F" connectors or standard female coax sockets?

Daniella Dean: The answer to the latter part of your question is "extremely unlikely", and with the somewhat limited info given regarding your location suggesting that you use Crystal Palace for reception, no transmission faults having been reported by this station nor are there any engineering works taking place.
Your problem is likely being caused by a fault in your aerial system.

Peter: Winter Hill uses the following channels/ (BBC) Ch50_706Mhz / (ITV) Ch59_778Mhz / (HD) Ch54_738Mhz / (SDN ITV3) Ch58_770Mhz / (COM5)Ch49_698Mhz / (COM6) Ch55_746Mhz. Another very low powered channel called MEN "might" be receivable, it being on Ch57_762Mhz What model of recorder are you referring to?

Peter: Yes, the 2500 is not the best of devices to use in locations where the two stations that can be received are Winter Hill and Moel-Y-Parc due to the commercial channels used by both being intertwined with each other.
Even the aerial out / in procedure is liable to be hit and miss because of the close proximity of the channels, but though the best in / out / in procedure I can see is as follows.
Aerial "out" until 48 is passed then immediately "in" to catch WH's 49/50, then immediately out to miss MP's 51/52, then in and leave in to catch WH's 54/55/58/59.
It would also have been of assistance if you could give you approximate location (post code of somewhere nearby e.g: a shop/post office, this for the purpose checking the angles that the two transmitters are being received at, and is your aerial rooftop mounted?

Richard: Its not really possible for anyone to be able give advice on a problem of this nature unless a persons location is known, post code or one from nearby (e.g: a shop / post office) as this is required for the purpose of accessing info on the transmitter covering the area plus the signal levels expected at the given location.

Joe: Sky+ boxes cannot be used for recording or indeed playback of anything previously recorded without a subscription being in force, as without same the box will just perform as a standard version.
As far as the second question is concerned, although the dish as such could possibly be used, but though this is provided that its fitted with a new LNB as the one already on it is most likely to be the older low band types that were used pre Sky digital.

Joe: In addition to that said and with regards to the old Sky dish, when you mention "making use of it", are you meaning within your own household? because if you are then why dont you just run another one or two feeds from the quad LNB that you intend to fit onto the Zone 2 dish referred to?
For neatness you could use twin coax known as shotgun cable, called this because of its appearance when viewed from end on.

Darren Cotton: Although it should never be taken as a foregone conclusion that 4G would have any effect on reception, that is unless living within a hundred yards or so from the mast, but though if any of Waltham's channels were going to be affected then it would be in the order of: HD (Ch58) / COM6 (Ch57) / COM5 (Ch56) and to a lesser extent PSB2 (Ch54)
If though reception was from Leicester's PSB only relay, then 4G is unlikely to have any effect unless being next door to the mast.

Cheryl: Is your dish an elliptical or round type? because if its the former with a rectangular arm holding the LNB, then "on top" of the rectangular arm where in LNB's holding bracket slides into it you will see a small hole with a stud in it, press that down whilst you wiggle the LNB's bracket out as the pin referred to is a retainer to stop the bracket sliding out.
With regards to the coax cable, provided that you have not caused a break in the braiding whereby you might have touched the middle core, then just wrap a piece of insulating tape around the nick in the outer cover.
