So after reading the responses on here I went up into my loft to check out what Amplifier I had.
This amplifier is used as a distribution amp as it sends the signal to 3 TV's
It is a Labgear LDL204 4G 4 Way, Freq. range UHF: 470 - 790MHz, Gain per port: 8dB, Noise figure: 3.5dB, with 4G filtering on DTV input.
I think my biggest problem may be my antenna as it looks like a standard Yagi with 18 directors So probably has too much gain for the strength of the signal I should be getting.
Maybe I should go for something like a Labgear LPCT Compact Log Periodic?
Anyone on here proficient in the dark arts of aerial selection?
Also after the recent works on the hannington transmitter I seem to be getting a much better signal on the com 7 mux with 85% signal and 60ish quality, but the quality seems to vary quite wildly.

Dre: if your getting 85% strength and 60% quality, that's screaming that your signal is too strong. So why bother to go on the roof to fit another aerial, when you are boosting your signal? Either perhaps bypass the amp, and see if you can distribute via another non boosting route, or just get some attenuated and kill the signal at the tv end - cheaper and easier.

Well for me to change the antenna is not a problem, and the labgear compact is only 10. So unless I can get another F-type connector distribution amp for less than 10, or 'some attenuated'(I have no idea what this is) for 3 TVs for less than 10, the antenna would seem the obvious choice.

Dre: Attenuators are small devices which plug inline with the coax cable going in to the TV's aerial input and reduce the signal strength. They can be bought for a few pounds on Amazon.

Hi, so I have changed the antenna for the Labgear LPCT Compact Log and that didn't reduce the signal enough, so I got an adjustable attenuator and fitted it straight into the back of the Youview Box.
Now as MikeP suggested I have set the attenuator so I have 80% on my strongest Mux which is PSB3
Now I get strength and quality different across the muxes ie.
PSB1 - 65St - 100Q
PSB2 - 75St - 100Q
PSB3 - 80St - 100Q
Com4 - 60St - 100Q
Com5 - 55St - 100Q
Com6 - 40St - 100Q
Com7 - 16St - 3Q
Com8 - 0St - 0Q
My distribution amp has a built in filter that removes any signals from Lte 800 4G

Now when I reduce the amount of attenuation All but Com 7 and 8 will go to 90St and 100Q
Com7 is 55St and 45Quality and Com 8 sits at 35St and 70Quality

This would seem to be the sweet spot.

I still don't understand why Com7 and 8 are so much worse than all the others tho.

Dre:

The probable reason COMs 7/8 are worse is likely to be due to interference from Crystal Palace.

As you have an adjustable attenuator, I would try reducing the attenuation a bit further. There is nothing wrong with 100% signal on your strongest muxes PROVIDING the Quality does not reduce on any of the muxes (and of course you are not experiencing any pixellation or sound breakup issues!) Bear in mind you may still see those problems on COMs 7/8 from time to time anyway due to interference.

Dre: Your Labgear LPCT Compact Log has a low front to back ratio of 17 dB.

It seems to me a high front to back ratio might be the way to reduce the interference from Crystal Palace referred to by Chris.SE.

According to its data sheet, the Vision V10-36FL Log has a front to back ratio of >34dB.

Maybe that's the way to go.

I'm thinking maybe I'll angle my antenna a little more to the south. That may reduce the signal and the interference? I think its probably worth a try anyway.
