Yep thought the same jb, picture seems ok however at the moment, will try it out tomorrow on another ariel / tv. Not sure the figure can be right, 100% signal and 10 % quality would have glitching all over the place.

rob: Yes, I also had suspicions that the quality and strength readings might have been accidentally reversed.
Anyway, you can maybe give an update if you manage to try the box out on another aerial.

I will do jb, however i still would not expect 100% signal with 10% signal, all seems a little strange that said when i plugged the logic 19 inch flat screen into the Ariel socket i had 100% quality and 0% signal on the screen and how in hell would that work and it did not name the region. However when i plugged it in at the Ariel point (run from point on wall under floor to Sony tv) showed signal at 60% and quality at 80 or higher and it identified the region.
Not sure what's going on there, is something strange happening in the cable under the floor?
All very weird.
regards Rob

Rob, you said "Not sure what's going on there, is something strange happening in the cable under the floor? "
Did you do the simple cable continuity check I suggested earlier? You could do this now on just the cable under the floor using a torch bulb and battery.

Hi Pikpilot,
Sorry if i am honest i did not really understand how to do this, i have a coax plug into the wall socket, a run of cable under the floor, a two way splitter which feeds one lead to the TV and one lead to a spare socket at the other end of the room. Could you explain this test is laymans terms for me, i have no experiance of this kind of thing.
Also if anyone has any advice on why i should be getting a high signal strengh and low quality (highest is %31) on the alba set top box i have borrowed would be great, I have already tried a varible attenuator which i turn the signal down to good on the sony with but the interference was still there and i lost quest etc which i watch.
Again it is only the channel 60 programmes which are effected everything else in perfect.
Cheers again,
Rob

Well another update,
just looking along the street i have noticed lots on new tv ariels and lots with what look like masthead amps on.
also i asked at work and someone there had exactly the same problem, Ariel split a few times and tvs upstairs fine but the channel 60 channels blocky at times just like mine. He ordered a powered 4g splitter and plugged this in the loft and it has cured his issue.Now thinking that all the masts around here this could be the problem. Anyway ordered one off ebay and will be here Friday so fingers crossed.
regards
Rob.

Well All,
Still puzzled over this one, signal strength on my Sony KDL37w5500 said the signal strength was high it does not show the quality, now i have this Alba set top box plugged in the signal strength says %100 but the signal quality says it is 9% and even lower but that cannot be right as the picture is not glitching and there is no sound issues.
So i cannot seem to find how the quality gets so bad and how i get the quality up, ariel aligned with a signal meter and had all the lights on, however what makes the quality low?
Sending me mad this one really, will update when i get the booster fitted but what is reducing the quality ?
Regards
Rob

rob:
Let us know what happens when you fit the 'booster'.
I would be very surprised if you need that amplification as you are only 7.4 km from the Oxford transmitter. Usually having too strong a signal causes the sort of problems you are reporting. Generally it seems that 70-80% strength gives better quality with fewer, if any interruptions/disturbances.
I note that there are mobile signal masts between Oxford Road and Bicester Road, not far from your location. It doesn't appear that any are 4G, but it may be worth contacting at800 (see https://at800.tv/) and asking if they are aware of any problems being caused in your area.

Cheers mike p,
Contacted them and they say there is not an issue. I am not sure if that's true however.

Hi Rob, you said "Hi Pikpilot,

What I said in earlier posts is that you should check the continuity of each of your cables. Easiest way is, at one end of the cable (without the splitters in) join together the inner and outer (pin and case) of the cable. At the other end either use a multimeter, or if use don't have one, use a torch battery and bulb in series across the pin and outer of the cable. The bulb will light if no fault.
I have come across a number of installations where people had not soldered the inner wire of the cable into the pin of the plug. What happens is that the wire does not actually touch the inside of the pin and the signal is only capacitively coupled. Sounds unbelievable but it happens when the wire is too short to reach the end of the pin and is held central by the insulation. If you don't want to solder it then there is another fix that works. Just put a kink in the inner wire before you push it into the pin of the plug. With all those splitters in place you are already loosing a lot of signal so a single connector problem will be the last straw. And it is not just about signal loss as a break in the cable will make the cable look like an un-terminated long wire aerial bringing in interference.
