This has happened a number of times now, more than I can recall. Early morning, 6am'ish, the TV shows "No Signal" for all channels, signal strength 10, quality 01. The transmitter is a Freeview Light one, in Bridgnorth. Have found it only to occur in the mornings. Is it down to 4G testing??

Pat Collis:

If the signal being received is marginal and not very good there will be times that you have perfect reception and times that you have issues.

It is common for marginal signal to be worst in the night and in mornings, working perfectly well during the day and early evening.

You may need to get your system tested to make sure its performing correctly.

regards

nerijus: I would think it pretty much impossible to put an aerial on the roof in your area and get nothing from Waltham, providing it's pointing in the right direction and is set horizontally.

If there is an amplifier (booster) connected to the aerial lead then if it's not powered it may well give nothing out.

I have enjoyed terrific HD reception for about 9 months, despite being in a relatively bad reception area. Then all HD channels started to break up about 5-6 weeks ago. I retuned yesterday and now the HD channels are not even there! I disconnected my PVR and retuned the Television Freeview receiver with the same result. Nothing else has changed. I am on the Heathfield Transmitter and live TN12 9AY. Tunbridge Wells transmitter is much nearer but an aerial man said it was just a relay from Heathfield so would not improve things. Any ideas please?

John McCann: I comment on here as a technical bod rather than an aerial installer and for that reason I'm not qualified to say whether the installer was right or wrong.

However, I have made the following observations:

We have exchanged messages on here before and I have previously said that you do not have line-of-sight to Heathfield, whereas you would appear to have so to Tunbridge Wells:

Tunbridge Wells (Kent, England) Full Freeview transmitter | ukfree.tv - 11 years of independent, free digital TV advice

(Unfortunately the terrain-checker I used then has since died.)

The terrain plotter on ukfree.tv suggests that the signal path is low to the ground in some spots, which are wooded or have trees nearby. So it's not surprising therefore that you might have difficulty.

Since switchover Heathfield and Tunbridge Wells have operated as a Single Frequency Network (SFN). This means that they broadcast on the same channels (frequencies), something which the digital system allows for. Therefore, the signals complement one another. The only thing is that Heathfield uses horizontal polarity and Tunbridge Wells uses vertical polarity, thus the complement is not as good as it might be because the aerial is opposite polarity for one of them.

The transmission power of Tunbridge Wells transmitter is slightly greater in real terms than that of the former four-channel analogue.

John McCann: It might be worth enquiring with your neighbour to see if he/she has started to have difficulty with the HD multiplex, that is if they have a HD receiver.

John McCann: The transmitter at Heathfield is 31km away and radiates at a power (ERP) of 20kW. Tunbridge Wells is 15km away and its ERP is 4kW.

"If" you had line-of-sight to both transmitters, the strength of the signals at your location would be about the same - Tunbridge Wells being a tiny fraction less than Heathfield.

So it seems that Tunbridge Wells should not be ruled out, unless there is some obstruction that rules it out.

Thanks Dave L. Not sure how to respond? So many points. Next door was perfect until a few days ago and now is very slightly pixelated in HD. The Aerials are identical and put up on the same chimney on the same day by the same guy. Both houses have Humax PVR and good HD televisions. What confuses me is that the aerials are only about 600m apart - so why the difference in reception???

Next reply Dave - How can I tell about line of sight? As Heathfield is nearly behind T. W. I assume the L. O. S. is identical?

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.
