On CurrentGen, there was such a thing as 'too high' signal strength - like SHOUTING in the box's lughole, for which a passive attenuator in the aerial cable was sometimes the answer.
I wonder if the new values ever go over 100, though; if not, we can't detect 'too high' any more.
Have you by any change got one of those passive Y aerial signal splitters knocking about? Worth putting it in the aerial chain if so, seeing if it affects the numbers, and/or stops the breakup.
Otherwise, it's punting a few quid on an attenuator from Maplins or similar, to see if it brings any benefits.

Hi Nick - there is a post on a similar topic, that in turn refers to a post on the BT forum, that states
Reporting of signal strength and quality has recently been standardised by the DTG (the UK body that lays down technical requirements and compliance for all DTT receivers). YouView have implemented this new standard as part of this update, and so the signal-strength reported by your STB may have increased, but will now be comparable with other compliant devices.
So the issue is one of definition and scale rather than accuracy. The fact this new system seems to be reporting 100% for many people and gives less evident distinction between the actual levels you have perhaps means it is less helpful though (although one should presumably interpret 100% as perfect for the box's requirements)

You would expect that to be the case, but the scale ends at 100. This is fine for signal quality, which presumably can't be better than 100%, but not for signal strength, which could be higher than the 100% limit of the scale.
I am not suggesting that is necessarily the case for Clint, but if I had a signal strength reading of 100% and the picture was breaking up, I would try an attenuator as Roy suggested.

Our worry is that on CurrentGen, 60-70% signal strength was comfortable, but above that could give issues.
And if NextGen is pitched so that, say, what was 65% before is now 100%, but what was 75% before is still shown as 100%, not as 115%, then we have lost our signal overload warning :-(

You can do that with an attenuator.
Our signal strength reading is around 60% depending on which Mux is in use, but that is with a 12 Ohm attenuator in the line to keep the Topfield happy.

But if Quality stays at 100% and the break-ups stop, then yes, it would seem so.
But if Quality has dropped below 100%, and/or the break-ups worsen, then we will need to look for a different explanation,

When a Freeview receiver detects a signal which is too strong, its automatic gain control (AGC) adjusts the tuner gain down to compensate. If the signal is _way_ too strong, the AGC tries to protect the receiver by overcompensating and turning the gain down much further. The result is often that the signal level display is quite low when the signal is way too high.
Adding an attenuator reduces the incoming signal, causing the AGC to "relax" and the signal reading will go up!

HD channels appear to suffer the worse. When I was on CurrentGen both quality and strength was STILL at 100%, I'm so confused. I've been messing with this for ages now and I've pretty much had enough of it.

What's your Quality now, and are you still getting break-ups?

Quality is still at 100% and yeah sometimes, it has fits of it, I can watch TV and it will be fine, then other times it's breaking up like mad.

That box supplies power to a (so-called) masthead (or distribution) amplifier. There should also be a wall-wart (brick) that plugs into an electricity socket. This, in turn, plugs into that box, which then supplies power to a (in your case) 4 way distribution amplifier.

Everything works just fine.
I think the WMA is for Wolsey Masthead Amplifier; and apart from being black, is probably just an updated version of yours, which is probably still doing a fine job.
If you switch it off, your TV service will stop, though, so it's not something you can really test :-(
