Simple-mindedly one would expect that the tuner would not be overloaded as long as the signal is below 100%, certainly if it's 10% below, but I suppose that doesn't take into account possible peaks. I'll give it a reasonable length of time to see how it copes now and if there are still problems I'll try bringing it down a bit with a variable attenuator.

Still early days but I think it's better. One "feature" I've noticed, though, is that when I take it out of standby the signal to the TV is lost for a few seconds (maybe ten or so, I haven't timed it).
This may be annoying enough for me to revert to feeding the signal separately.

I think a quick update is in order after all this time.
I've had no further problems with signal break-up or notifications of recording failure due to signal problems, so I can say with some confidence that the tuner unit works reliably with a 90% signal level.
However the issue I mentioned earlier regarding occasional loss of signal on the TV when I switch the unit out of standby still persists. When this happens it typically takes around 20 seconds to recover which is clearly unacceptable. I have even had instances of signal loss whilst the unit is on, suggesting there is some unreliability in the loop-through. I haven't done anything about this yet but I'm minded to reinstate the booster to split the signal using variable attenuators to optimise the levels to both the Humax and the TV.

A final update: The occasional loss of signal whilst using the loop-through has impelled me to revert back to splitting the signal. I bought a couple of variable attenuators as suggested by grahamlthompson and reinstated the second booster. With this arrangement, though, I found I could not reduce the signal below 100% with either attenuator so I tried a simple 'Y' splitter instead of the booster and hey presto found a good range of adjustment available. There was clearly a lot more signal available than I thought. I've now set the strength of the most powerful multiplex to 80% so hopefully all should now be well.
In addition to the signal being lost when coming out of standby it has sporadically been lost whilst the unit is in standby so splitting the signal seems to be the only recourse.

I also have the 2000T and a 4000T and get the same signal loss on the TV with both of them during taking the box out of standby, or it about to record. Humax is the only make of PVR I have had that does this. Still it does not matter to us as we watch the PVR's more than live TV.

Still it does not matter to us as we watch the PVR's more than live TV.I had the exact same issue with my 2000T when using loop-thru, TV is a Panasonic. I would either get a blank screen or picture flash and momentary pixellation. That was via the TV's own Freeview tuner when the box was coming out of standby to record the early evening news.
I employed a passive splitter from the aerial wall socket which immediately cured the problem - I think the splitter cost the princely sum of £1.64p - well worth the outlay.
Prior to the 2000T we had a Panasonic Freeview HDD recorder and this never once interfered with the TV picture in any way - definitely a Humax issue.

Yes Humax have been making PVR,s for years now, you would think they would have got it right by now. I have watched the Signal on the TV drop from 80% down to zero while the 2000T and 4000T boxes are warming up ether coming out of standby or getting ready to record. I have had, and still got other makes of PVR but never had this problem with the others. To me it seems it must be a power problem when the PVR's start up.

Fitting the splitter could have moved the coax away from the hdmi lead. Easy to prove - remove the hdmi cable completely, if the TV tuner is OK when the box is on you have the answer.

I'm inclined to think this is a problem with the way loop-through is handled. Anyway, splitting the signal has resolved the problem for me but I agree with the other posters this is something Humax should have sorted out.
I'm somewhat relieved to discover I'm not alone in this. I was beginning to think my box was faulty. TBH, Graham, I can't be fagged to play around with it any more now I've got a setup that works.
