BBC1 and 4 unwatchable in Haddenham and Witchford. Have to stream them.

I have done endless manual resets and still have terrible reliability issues on Frequency 27, in other words all the BBC channels. There is nothing wrong with my aerial, nor with my television a Panasonic Viera. I live at SG8 8SP and can actually see the transmitter from my house. Why am I paying a licensing fee if I'm getting such poor reception and how can I improve it?

Dr C A Fox: If you can see the transmitter then there's a good chance that your TV is being overloaded with too much signal (try fitting an attenuator to reduce the signal strength). What signal strength and quality readings on other channels such as ITV?

Dr C A Fox: & Roger Fentiman: & Peter Reynolds:

There is Planned Engineering work at Sandy Heath at present with "Possible Weak Signal" so this is the most likely cause of the intermittent/temporary loss of reception. With the current weather High Pressure system this won't help matters either.

Hello I have a very good quality aerial which was fitted 4 months ago for Freeview in the kitchen we have sky in all other rooms .

On my Freeview TV we are having constant pixelation and drop out of signal I have checked with local residents around the area who are also experiencing serious reception issues with there Freeview HD TV .
I have returned and checked cables.

Those sort of problems are not due to any faults anywhere, but are mainly due to weather conditions. Patience is called for.

Earl Thomson:

It looks as though you are in a borderline reception area. DigitalUK doesn't have any predicted Freeview reception for your postcode. This site seems to think your transmitter should be Oxford which is stupid because a terrain plot clearly shows two hills in the line of sight, the first being about 1-2km away, the other around 7km IIRC. I can't easily get a terrain plot for Sandy Heath but looking at the coverage map and street view I'd guess it has a better chance, so a good aerial installation would be a must.
BUT as it's going to be borderline reception it's going to be very vulnerable to interference from long distance DX interference when weather conditions (usually large high pressure systems) allow as we have at the moment.

If you find your Freeview reception is too unreliable then I'd resort to Satellite. I don't know what sort of LNB you have on your Sky dish, but if there's a spare output you ought to be able to get Freesat with a Freesat box, or your TV may even have an in-built Satellite receiver.

Earl Thompson . I agree with Chris . You will definitely need a good aerial amplifier near the aerial . Even then you will l be susceptible to some continental interference . I would recommend going to freesat for a reliable signal. You could have the SKY dish LNB changed to have an output to connect the freesat receiver too or install a separate dish just for freesat.

Installing a separate dish would require planning permission. Only one dish is allowed on any property without planning permission, adding a second needs an appropriate application to be submitted.

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.
