Is the transmitter output the same in all directions?

Glyn Hammond:
Before you rush off to get an amplifier, what is the state of your coax?
How long ago was the aerial replaced? Was the coax replaced at the same time with quality double screened (eg.CT100 standard) coax?
If it's old coax and there's been any ingress of water at anytime, if the outer sheath has become brittle etc. this will all affect the signal at the set. Certain problems can cause "standing waves" in the coax which can be specific to one frequency, and maybe in your case affect C47. Other problems can just cause severe attenuation especially the higher frequencies.
Were you getting the HD multiplex before the aerial was replaced? If so, I'd be having a close look at the coax if it wasn't replaced. If it was, a thorough check of all the connections.
If you've never had the HD multiplex then may interference could be an issue. Check you haven't got any older equipment (eg.VCR's etc) with RF output operating below C47.
I take it you haven't got any splitters for providing signal to more than one device.
Even though a signal strength reading at the set of 51 for C44 seems low, I'm surprised that it's all 0 at C47.
Should it turn out to be a case of needing an amplifier, make sure it's one with a variable gain control. Too much signal can also cause problems, especially if there are any mobile masts nearby. I would be trying to get a filter from restoretv.uk in any event.

Chris.SE: Thank you for the additional comment..
I have changed the aerial only. I had been receiving C47 at that time.HD signal lost April this year.
All channels lost this week as the amplified splitter has become faulty. Pixelating and loss of signal.
I have one tv working to c41 & 44 by connecting the aerial direct to its downlead.
There is no signal on c47. No engineering work.

Glyn Hammond: Now that you've told us you have an amplified splitter, that seems the most likely culprit. I'd replace that before you do anything else.

Connect the aerial direct to the TV and see what signal strength and quality you get on each channel.

Chris.SE: I've ordered a replacement amplified splitter.
After moving the aerial to a point where I get best signal on c41 I now have following
C41 61; C44 50 and C47 32 signal readings for tv to aerial.
Should have splitter on Monday. It has a 4g filter. Fingers are crossed.
Thank you

With that drop in signal between C44 and C47, I would be looking at replacing the coax from the aerial to the splitter position, and from the splitter to any TV where there's an external run or the coax sheath is looking degraded.
