Andy L: No. Unfortunately Stockland Hill isn't getting the new HD multiplexes, so the HD streams of BBC Four, CBeebies, BBC News and Al Jazeera won't be available.

does anyone else have problems with the Craigkelly transmitter?
Sometimes I have no freeview signal at all and other times it is very strong....it is so annoying as it seems to happen when something good is on TV

david s: No engineering work is being carried out at the Craigkelly transmitter and no faults have been reported, therefore in order to eliminate the possibility of the problem being caused by something connected with your own installation such as a faulty coax to aerial connection, you should try and make an enquiry with a neighbour to find out if they are also experiencing similar problems to yourself.

Dave Lindsay,
I have tried to do a full scan and it picked up over 68 Digital channels but when I went through the list after the scan, they appeared either blank (black) or very pixelated and most of them were all around the 800 channels with nothing being shown.

Bharat: If you look on the Terrain plot and tradeview from your postcode, your only about 27km from Midhurst, with a clear line of sight - so you should have a really decent signal without any need for the booster at all.
If you getting 68 channels of rubbish, then the first thing to do is to do what David suggested - check all your connections, to make sure there isn't a loose connection, etc somewhere, because your signal strength should be much higher. As David said, see if you can check with another tuner as well, to make sure the TV isn't duff.
The second question is - are you tuned to Midhurst? Midhurst is on channel 55, on a bearing of 28 degress. If you are trying to pick up anything else, its all very ropey. I notice that Rowbridge/Hannington in not far off the same bearing for Midhurst, but is on Channel 24/45. If your TV is picking up Rowbridge, etc first, then no wonder your not getting anything.
It could be more than one factor thats causing your problem, so check everything and find out what transmitter your actually using.

Bharat: I suggest that you try another television or a set-top box in the room where your issue is. This would serve to either rule out possibility that it is the TV at fault (or else suggest that the TV is at fault). Swap the lead from the wall socket to the TV to discount that as a possibility.
If you've done that then you have to ask yourself what else can you check?
For example, if the aerial is on the roof and the cable runs down the wall and through the wall, on the other side of which is the aerial socket then there's probably not a lot more you can do.
I looked at your road on Streetview and couldn't see many TV aerials (I spotted one), although there are one or two satellite dishes. If yours is in the loft can you access it and check that the wires are connected?

my aerial is in my loft, I will check this to see if all the wires are okay and the aerial has not moved. I did a brief check before all this was happening and nothing had changed.
I don't think it is the TV as my sky box functions okay and everything else (all other functions/features) work but I will check it with another TV set.
I was planning on calling out an aerial engineer from NORSAT in Horsham to see if they could resolve the problem - do you have any experience of this company or staff from NORSAT???
Thanks

Dave Lindsey,
I have just checked the amplifier and it is a mast head one...
the one I have is as follows: taken from their website (Fringe Electronics Ltd)
Fringes P1285 and P1285-2 are an industry
benchmark as to what a masthead power supply
should be.
Available with either F or coaxial sockets. Both
power supplies are short circuit protected and built
to extremely high standards using premium German
transformers.
P1285-2 features internal inductive splitter for twin
outlets.
It has one input and two outputs with a standard TV connection, I think it might be a f type coaxial, but I could be wrong.
Could this be what has failed.

Bharat: The P1285 is a power supply only:
Power Supplies
It is used in conjunction with a mast-head amplifier, such as these:
Masthead Amplifiers
They are so-called because they are designed to be fitted outside on the mast. Because you can't have mains electricity outside, they require a separate power supply which feeds a safe low voltage up the aerial lead.
In your case the mast-head amplifier is, I assume, in the loft adjacent to the aerial. If the power supply is also in the loft then they are in close proximity, which is fine.
There are a number of possible reasons why you don't have a signal:
- fault with the power supply
- fault with the mast-head amplifier
- poor connection or wiring
I would certainly do away with using an amplifier behind the TV set. The one fitted in the loft should provide sufficient signal that it doesn't need amplifying further.
An f-connector is one which is threaded and therefore requires screwing together to ensure it doesn't come apart. The power supply in question is available with f-connectors or standard coax TV connectors that just push together (as on the back of a television). See:
Satellite, Television, FM, DAB, Aerial, Coaxial Cable, Plugs, Sockets, Connectors & Leads
What you're looking to do is disconnect the amplifier from the aerial - look for the box somewhere on the lead from the aerial to the power supply. Then connect the wire from the aerial to the wire going to the room where your TV is. The only thing is that I imagine that the gender of the connectors may be the same and so they won't go together.

Thanks Dave for the information.
I will locate the aerial in the loft and trail the wire to see where the amp/power is and see if I can reconnect both wires together and then retune the channels.
If I continue using the main power amp behind the Tv, will this cause a problem or should I just remove it as its not required.
