Martin: Loss of signal. Lots of pixilation on all channels.


I believe the aerial is directed at Stockland Hill

Tacolnston transmitter is working correctly at present and no faults reported.

Please check your aerial system and connections.

Please check your aerial cables and connections. If there are coaxial plugs/sockets please unplug them and refit. That will clear any corrosion/oxidation of ther contacts, which is a well known cause of the problems you report. DO NOT RETUNE.

I have an Edison HDMI Modulator for my CCTV system and have tried setting it to various channels, no matter what channel I select, when in use I cannot tune in any bbc / itv etc channels on my TV's.

Any help on channel selection to eliminate signal loss would be appreciated.

Location - Humberside

Kirk:

Assuming you are tuned to the Belmont transmitter, try using a channel between 40 and 49 as they are not used by that transmitter now nor in the future.

However, it could be that the HDMI cables are radiating themselves and disrupting the TV UHF signals carried by the aerial cables- expecially if they are close to each other. So try moving the cables as far apart as is reasonably possible. If that helps then it is worth considering buying better cables with improved screening.

Thanks for the Tacolneston advice. With no equipment changes the Channel 56 signal was off and on for me on Thursday/Friday (varying no signal at all to 90%) but stable since Saturday pm. Maybe there has been some 'tweaking' going on and I am right on the edge.

Hmm,. Channel 56 Tacolneston back to zero signal again, channel 55 (also a low power transmitter) is 95% signal. Something must be going on!

Chris:

Have you checked your aerial connections as previously suggested? Poor connection can cause loss or interuption of just one channel. There is no reported work at the transmitter at the time of writing.

Yes, I have checked these thoroughly and re-terminated a couple I thought might be imperfect - no change. What I can't understand is why COM7 on channel 55 is consistently 90% signal strength, 90% signal quality, whilst COM8 (which I thought had about the same 24kW output at COM7) and is on a bearing of 142 degrees from Tacolneston to me, and therefore not restricted by the radiation pattern (according your polar diagram), is currently zero signal today and yesterday (but was solidly 90% on Saturday and has in previous weeks been absolutely fine). 8MHz higher frequency should not affect reception that much.

Are we sure the wind hasn't blown the COM8 aerial away!? A comparison of channel 55 and 56 signal strengths at your location might be interesting.

Chris:

The aerial at the transmitter radiates ALL the channels, there is not a separate aerial for any of the multiplexes. They all use a design known as a trapezoid slot aerial where the signals are radiated from different sections of the slot depending on the frequency. So they are all radiated by all the trapezoid slots and not by separate aerials for each multiplex.

An 8 MHz difference in frequency can make a considerable difference to the transmission and reception of the signals.

Looking at the Digital UK Coverage Checker for your location, see Coverage Checker - Detailed View it shows that reception of COM8 is expected to be poor and unreliable, as it is for other multiplexes from Tacolnston.

Where is your arial positioned? If it is possible, it might be worth trying a different position - on the othert end of the roof perhaps? Such a change has given good results in the past in my experience.

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.
