I live in Hampton Court (KY8 9BZ). I have two aerials in my loft, pointing 107 degrees from magnetic North. They were in place when we bought the house.
They both have horizontal 'blades' (pointing left - right).
The aerials were in place when we bought the house and deliver a signal to 4 sockets in the house.
We have never had any problems with reception, aside from slight pixilation when scooters go past, until the end of June when we suffered a big loss in signal resulting in loss of most digital channels. There have not been any changes in the house that we know of. I have checked the aerials, which look just the same as normal. I noticed that they both have red plastic stoppers at the end - don't know if that indicated the aerial type or not.
Any advice gratefully received.

Nick: A red stopper means they are Group A aerials. Crystal Palace uses Group A channels exclusively, even after switchover, so there is no need to replace them because they are the wrong group:

Aerials, TV Aerial and Digital Aerial

According to Digital UK, Crystal Palace is on a bearing of 82 degrees. I presume this is relative to either True North or Grid North. Magnetic North moves over time.

You may be in an area where 4G at 800MHz testing was taking place:

at800 West London 4G tests

According to what we know on this site there are base stations on Hampton Court Way for the four mobile network operators. On Streetview they can quite clearly be seen, all to the south of the river: two by the railway line and not far back from the river bank and three a few tens of metres away on on the grass verges.

Nick: You say there are two aerials feeding four points. How do the feeds split? Does each aerial feed two points?

If there is a powered splitter (distribution amplifier) involved then it might be that you can do away with it because the TV signals are so strong now switchover has taken place.

Dave: Many thanks for your reply. Since the aerials looked professionally installed I was loath to move them, but I also worked out that Crystal Palace was the best transmitter for my location and that it was on a different bearing to the current direction - so I moved them. This boosted the signal strength and quality considerably and I am able to see the standard channels (BBC1, 2, ITV, C4, C5) very well. I wasn't able to get other channels like Dave and Really etc. I thought about this again today and it occurred to me that if I am now receiving a signal from a different transmitter, I might have to re-tune (auto tune) the TVs?
I will also check at800.co.uk as this might explain why the signal suddenly dropped out and didn't return.
The aerials are both installed on the same pole and although are different brands are otherwise similar. They are mounted about 30-40 cm apart. All the wires go into a small box, but I will have to investigate further to tell you more about this.
Thanks again.

Nick: Whilst it is always good practice to check that the TV or box is tuned to the correct transmitter (and that you aren't trying to affect better reception with the aerial pointing the wrong way), based on the prediction of what might be available it does seem doubtful that this may be so.

Nonetheless, confirm by viewing the tuned UHF channel on the signal strength screen while on each of the following:

PSB1 | BBC One = C23
PSB2 | ITV = C26
PSB3 | BBC One HD = C30
COM4 | ITV3 = C25
COM5 | Pick TV = C22
COM6 | Film4 = C28

For a full list of service by multiplex (mux), see:

DTG :: DTT Services by Multiplex

Having checked one service from each mux, the rest "should" be the same.

The COM channels use a signal mode that is less rugged than PSB1 and PSB2. This is so they can get more services in (more shopping channels!) and it comes at the expense of making them more fragile.

Consequently, the direction of the aerial will probably be more critical for them. I am not an aerial installer but I know this from my own experience. Whilst all five standard definition muxes are radiated at the same power from my transmitter, which is Emley Moor, on turning the aerial off-beam the COMs are lost but the PSBs are still strong. I guess that as Crystal Palace also has all muxes at the same power (not all do) then a similar situation may exist.

Dave: Brilliant feedback. I really appreciate the effort you've gone to to help me.
What you say makes sense based on my observations so far. I will do what you suggest tonight to see if I am receiving a good signal from a service from each mux. My TV has a good info screen with signal strength and quality bars. When I realigned the aerial the other evening it was more of a hunch than a definite intention and I can probably improve the accuracy as well.
Will let you know the results. Thanks again.

David Lindsay,

Not familiar with the blog system so have only just discovered your replies to my July 1st!

Why should Ch 49 be the only frequency affected? All the others are 10/10.

David Curtis: I can ask you the same question in reverse: Why should you be receiving four (five if it's HD) muxes with excellent signal quality?

As I said, you do not have line-of-sight due to the high ground on which Crowborough sits being in the way. There is also potentially another obstruction at 7.5 miles:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


Signals travel in straight lines. Because you don't have line-of-sight you are relying on diffraction which is the signals bending around the obstruction. Different frequencies bend differently so as a consequence in non-line-of-sight situations it can be found that all signals aren't received at the same level. Indeed in some places one or more signals may be good and others apparently non-existant. The objective is to site the aerial where they are all good.

I should also add that there are also a lot of trees in the way. So "if" it isn't the defraction issue then it could be refraction caused by the trees, such objects often affecting one or two frequencies whilst allowing others through seemingly unscathed.

Hi, im wondering if someone can help.

We have 3 tvs, two have integrated freeview the other used an HDR-fox T2. All have been working seamlessly.

Yesterday we have a massive thunder clap overhead and since we have had really intermittent quality. the tv upstairs has a few freeview channels and is missing 1-5.

The aerial is in the loft.

Is this just a transmitter at reigate issue and will eventually sort out or something else.

Ive also reset all freeview as suggested.

thanks
steve

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
