If I pull out the brown aerial cable from the UHF then I lose the tv signal. Is this the one then that feeds my tv?


Yes, try it on a different output, or bypass the amplifier when yo get the female joiner.

Thanks for your help again.

 

No, the black aerial cable was connected to 1 on the side of the unit, not Full.

Getting far too complicated now lol.

 

I took out the brown cable from UHF and connected it to one on the side - no tv

 

I then connected the black socket to the UHF - no tv

Connected it back to how it was originally.

 

Strength - 95-98%

 

Quality - 60's%

 

Then both drop to zero and picture breaks up.

Then try the variable attenuator, and adjust it to a srength of about 70%, I think its still a high signal level problem over loading the YouView box.

Hopefully, that should fix the problem. If it does not, then the only thing left is to get the aerial and distribution checked.

As I said before, the amplifier is very old and may be distorting the digital waveforms.

 

This may not be noticeable on a TV, which is much more tolerant of errors, but would upset the YouView box, or other DVR, which need a good error free signal to ensure reliable recording.

 

You could replace the amplifier yourself, as its quite easy and not expensive, and includes a 4G filter, which your old one would not have. Its possible that 4G is causing some issues, so having a filter would be beneficial.

 

Here is one that should be suitable.

SLx 27820HSG-4G Four Output Aerial Distribution Amplifier – 4G Compatible £13.49

There are for outlets (left) and one input (on the right). The other connector on the right is for feeding additional distribution amplifiers.

Changing it would bring the system up-to-date.

Ignore that link, no stock. Will try variable attenuator first then look at new amplifier, that one you mention is £11 on Amazon.
