AlgernonBlack: So your actually saying that you did have excellent reception, but your going to Freesat anyway?

Mike B.
My problem all along has been the failure of Freeview due to weather. This year has been awful.
The transmissions do not provide reception of all programmes, to all viewers, all of the time, so I have moved to FREESAT. It is brilliant. Plus there are a host of additional channels available free.

AlgernonBlack: Freesat is an excellent system, and of course has no problems with local weather.

However. it seems that many of your problems might have been caused by too much signal strength, rather than too little. Digital via terrestial has been successful for most people, most of the time, and once problems have been overcome, offer excellent service with little need for extra expense.

I live in Swindon, Wilts and our freeview reception was perfect until a short time ago.
Then we lost many channels ITV, CH4, CH5 , E4, Film4 and many others, yet we still have BBC1, BBC2 and a number of others. I received a filter of some sort identified by CH60 on it and a leaflet saying that due to the turning on of 4G system this
'might' interfere with freeview reception. If I connect this filter between the aerial and the mast amp or boost this will allow me to receive all signals again and normal reception as before. Well I've connected it and it doesn't work. When are the authorities going to stop their greed for money. They should not have turned on 4G until they had made sure it did not affect any other system freeview or anyother one.
Unfortunately, because of the revenue generated from the mobile phone companies the authorities knowing that the 4G frequency system would affect freeview still went ahead with it because of the money it will give them ( the mobile phone companies and the authorities). Well it is totally un-acceptable and we the people are paying for our TV licences. So, when are the authorities going to resolve this freeview reception problem ?

Jeff Boyle: In answer to your question, they won't because the spectrum has been sold.

The company Digital Mobile Spectrum Limited, which trades as "at800", was formed by the mobile operators and is charged with alleviating interference by providing one filter per household in most cases.

If the filter supplied does not solve the problem then at800 must provide another solution, but this requires the viewer to contact them rather than a web forum which is not connected with them.

Jeff Boyle: The answer to the question is not as I said, although it is true that the decision has been made and that the spectrum has been sold.

The authorities can only resolve your reception problem when you tell them. If you haven't spoken to at800 then they aren't to know.

Jeff Boyle: Last time I checked, the TV Licence goes towards the BBC channels and since you still have those, your comment about the licence is a bit pointless!

But if you actually want to solve your problem, get in touch with at800 as Dave says - they will tell you definitely whether 4G is the problem. If not, Freeview reception, unless it is external interference, is your responsibility.

Go to Contact at800 / DMSL | General Enquiries | at800 and phone them tomorrow.

Dave Lindsay:

Hi Dave,

I shall indeed be contacting this at800 company. I installed a proper digital tri fold aerial in my loft. I connected it to an 8 tv booster
amp both from Maplins. I did all this over a year ago and I never had a problem with freeview reception. The only problem I have is now and since nothing has changed at my end. Then the problem is at the transmitter end and or the 4G frequency system. The evidence and data speaks for itself this being all the many people writing in complaining about the same problem with freeview reception. In addition since we have an upfront admission by this at800 company that this 4G transmission 'might' affect freeview transmission. Again I state that they should not have been allowed to begin 4G transmission unless they had resolved all known issues and they already knew it would affect freeview. So, can anyone tell us why they still went ahead with the 4G transmission ?

This is causing myself and many other people major hassle not of our doing. Yet we are the one's that have to do all the running around
to get it resolved. I wonder if all the CEO's , Directors and hierarchy of the companies involved with the 4G transmission have this problem with their freeview reception in their homes.

Jeff Boyle: The "problem" is with your system due to the strength of the 4G signal that it is picking up. It is Freeview reception that is affected, not Freeview transmission. The solution can only ever be as it is now: filtering out the 4G signals.

TV aerial systems don't tend to be fitted with expensive filters that only allow through the frequencies used by the desired transmitter. Had they been so then there would not be an issue.

Some tests were run earlier this year and the results were that fewer than expected would be affected:

Expecting 4G interference? Tests now show that you have a one in 300 chance | 4G-at-800 | - 11 years of independent, free digital TV advice

If people wish to spend their time writing to complain then this will achieve nothing, other than allowing them to have a moan. The decision to use the 800MHz band for 4G has already been taken. The time for viewers to make comments was when this was being planned.

The solution in most cases is to fit a filter. Where this doesn't work then at800 has an obligation to take other steps. It is hardly going to take such steps with a particular household - before the 4G transmitter is switched on - just incase a filter won't work!

In your case the filter should be fitted between the aerial and the signal amplifier.

I was about to post about the filter location and then saw the last line of the post above.

A filter should always be placed after the aerial and before the amplifier. The reason is that if placed after the amplifier, the amplifier input will try to amplify the strong unwanted signal (4G CH 60 in this case) and the amp can be overloaded. The result of that is is non-linear operation, possibly creating new unwanted interference on other frequencies, and with some amps, an automatic reduction of gain across the whole frequency range.

Go into the loft and place the filter before the amplifier and let us know the result.

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.
