Adrian put finger to keyboard:
There's no point chaining amps, you're taking a low-strength low-quality signal and amplifying it into a high-strength low-quality signal.
It's a bit like hoping to get a 15x digital zoom as good as a 15x optical zoom.
What does digital UK suggest in terms of likely signal strength and quality?
Hmm. Using that info does not give me the results you are quoting :-)
well that depends on who you are. It is actually totally trivial and costs pence.
But of course pence are pence, and you don't put things into STBS TVS and boosters that you dont need to - or didnb't need to.
indeed, and a bloody eyesore compared with a loft aerial.
Green for BBC A, D3&4, BBC B HD. 86/87 "served" for each. Yellow/Variable for SDN, ARQ A, ARQ B. 51-58 "served" for each.
which side of the river?
How much of a "bit" East? By my reckoning you should have a nearby Welsh DTV relay station practically sat on top of Hay on Wye at Clyro.

Local topography can make a very big difference to which of your options actually work. My parents set in Manchester can (very annoyingly) see the Welsh channels from Moel y Parc in an antenna sidelobe 60 degrees off the main axis to Winterhill with enough signal to totally confuse Panasonic TVs now that the Welsh station is running on full power and using low band frequencies that are found first.
A default retune all fills up important mainstream stations with their Welsh version since the stupid Panasonic firmware puts the first found on the master location X and the second on 80X. I understand this very common problem is well known in Manchester telly menders circles.
North.
Not very far.
Ah. That's interesting.
That's because it can be used all over the world, and the UK options are only relevant, and therefore only become enabled, to someone who enters a UK location for the receiver. You could, of course, have read the instructions on the page to discover that for yourself. However, try this for Hay-On-Wye (used to love that area):

Unlike having a nuclear, or any other, power station between you and the transmitter, which would probably block the signal completely.
What a fatuously irrelevant th>
Definitley high gain up a big pole needed
Clyro only caries 3 muxes
That was after I entered the postcode.
And what happens when you click the tinyurl I gave?
Maybe, but it is close enough to him that a coathanger plugged into the aerial socket should be enough to get a signal of some sort.
With respect, that does not really tell you they are a pair of amps. Inline PSUs look pretty much the same as some amps, and the coax needs to loop through them so that they can feed power up it to a remote preamp nearer the aerial.
Can result from too much amplification, plus a number of other causes. I know you have tried one and then both, but have you tried just the second amp on its own?
the aerial.
on its own?
Also don't forget to take the Belling plugs apart and check to see that there isn't a "whisker" of copper braid shorting things out. You wouldn't half kick yourself if you missed this common cause of a duff signal.

One way to tell them apart is that an inline PSU will put some voltage onto the downlead which a cheap multimeter will be able to measure.
Isn't it annoying that these TV diagnostics are in terms of % using an arbitrary undocumented scale that is probably logarithmic. ADSL modems at least provide sensible units of dB signal to noise levels whereas TVs go out of their way not to provide meaningful information.
Or no amps at all - direct connection to the decoder. Modern digital decoders seem to be pretty good as far as sensitivity is concerned.
Coax cables are cheap.
How?..
BY what mechanism?..
