i have put everything back as i had it without the 6db attenuater and i have placed it with the 4g filter into in tv2 (upstairs) and i have 84 84
I seem to get a low signal and quality with it when it is inplace

Just so that we both are aware of this problem it goes like this.

The way that I have it now for upstairs the 4g filter is in the TV and I get signal 84 84.
When I place the 4g filter via the in tv2 coax I get signal 15 quality 0
If I place both 4g filter and 6db attenuator upstairs I get signal 35 quality 0 and the is pixelated.
If I place just the 6db attenuator in TV upstairs I get signal 35 quality 0 .
I have tried this in every way that I can.
Without the booster I receive .

Is it just me or is there some kind of that just cannot be explained.
But when I do the same downstairs there is no change, besides a few where the quality is lower than it was as above message

I think all this suggests that there are two things going on.

1) There is some and it seems to be affecting the upstairs TV more than downstairs. When you put the filter in the for TV2 it seems to be having little effect (if any), but if you plug it in to the back of the Bedroom TV you get 84% 84% if I read that right. This suggests most of the interference is being picked up in the coax run from the booster to the TV. This could be that there is some hidden nearby that has the interference in it and is radiating to the coax, or just the particular lie of the coax acting as an for the interference. So I would leave the 4G filter in the back of the TV.

2) There is also some signal overload. (BUT the overload could be caused by the Interference and not the DTV signals that you are wanting to watch!) This is proven by the fact that when you insert the attenuator, the signal on the bedroom TV goes up (the reverse of what you'd intuitively expect!). It's also proven by the fact that when you put it in the aerial input or the downstairs TV the signal stays on 100% BUT the QUALITY goes up - this latter result is a typical indicator of TV set front-end overload, but as I've already said probably more due to the interference. When you overload even more, the quality will go to 0% and the signal reading also goes down - again the converse of what some may have expected.

So one combination that seems to give adequate? results at present is 4G filter in back of Bedroom TV, and the 6dB attenuator in the back of the Downstairs TV (because quality goes up!).
There is something else to try and more to suggest, but I'll post this first, so you can confirm you've followed what I've said and things are working as I've understood it.

You could be right with hidden cables as they where underneath the floor boards. When I saw them doing the works , they where left over cables. I'm unsure at this time if theses where removed or left, since they were old wires.
The only difference to the plug sockets what was rewired was made higher than they where before.
The joint to bedroom 1 and 2 is that after measuring from the wall to the plug socket both measure the same length. In other words back to back.

So if you can post the & figures for both sets with the 4G Filter in the back of the Bedroom TV and the 6dB Attenuator in the back of the Downstairs TV, it'll hopefully confirm what I'm expecting.

Having done that, there is one other combination worth trying to see what the figures are -
Put the 4G Filter between the and the , and the 6dB Attenuator in the back of the Bedroom TV and post the figures for both TVs.

As asked I have placed the 4g filter in bedroom TV ( 84 84)
I also did the same downstairs with the 6db attenuator ( signal 100 quality 95)
As u have advised me to do as in 4g filter between the and the TV in bedroom goes down to signal 35 quality 0. This with the attenuator plus same with out in the back of tv in bedroom Signal 35 quality 0
Downstairs the signal hasn't changed much. 100 signal quality 84

Hi there, well it does confirm that a lot of is getting to the bedroom TV via it's coax, some better double screened coax might improve that situation.
At present the best option is the 4G Filter in the back of the bedroom TV and the 6db attenuator in the back of the downstairs TV. The sets should be capable of coping with 84% & 95% quality without much noticeable degradation, but it's still desirable to improve on this where possible.

Now, because your TV's are older 720p sets, they won't have a DVB-T2 tuner necessary for getting the HD . Because you are in an "awkward" location, any reception of COMs 7&8 if you get an DVB-T2 TV or Set-top Box, is likely to be somewhat weakened by the Ch.59 Filter which doesn't have a very sharp cut-off and can reduce Ch.55&56

AT800 also do a Ch.60 Filter which is higher quality and has a sharper cut-off. My suspicion is that you'll also benefit from one of these even in current circumstances as you are surrounded by Mobile Phone masts (7 of them) 2 of which are more or less on the line of sight to , and the same situation if you were to go for .
Do any of your very near neighbours have an pointing at Emley Moor?
Do any of your very near neighbours have an aerial pointing at Bilsdale?
Do any of them get COMs 7&8 - BBC News HD and BBC4 HD , 4Seven HD & Quest HD etc.?

Thank you mostly appreciated on your input,.
Would I be able to get hold of an at800. Ch 60 filter inregards to where I got this one from which was .uk

I do have a neighbor a few doors down that has an pointing towards
He receives all his via a ee set top box. He does get all channels including sports and movies, but his TV is connected to his ee modem even though he has an aerial

I don't have any neighbors who's aerial is pointing to wards , so I'm guessing I'm the only one.

I just want to check on one bit of technical info before I make my suggestion, as there are two different standards of Ch.60 filter.

Richard caywood:

The filter you want to try and get is a Filtronic UK-PSD008-V5-P DMSL LTE 800-DTT Consumer Filter (CH60) which you should be able to get from at800 at800 | 4G & Freeview | 4G interference | 4G Filters | 800 MHz phone 0808-1313-800

I wouldn't mention that you've got a filter from UK, say a friend has lent you a Ch.59 filter which improved the situation but has not cured it. Tell them that you are surrounded by 7 Mobile phone masts (they should be able to check that themselves anyway) and the problem has got worse.

Don't mention that your current sets are not HD getting the HD multiplexes. If they ask what they are just say the are LG you're not sure what model.
Explain you are in a weak spot being in a dip and the COMs 7&8 multiplexes on Ch. 55 & 56 are especially weak, the Ch.59 filter is not helping and that you've been told that the Ch.60 filter is a more effective better filter that doesn't affect Ch.55 & 56 the same.
