Freeview reception at BT28 3LQ


For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.

You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.

You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.

Look in your TV's tuning section and double check you are correctly tuned to the UHF channels for Black Hill.
The correct UHF multiplex channels for Black Hill in the order PSB1-3, COMs4-7, Local -
are C46, C43, C40, C41, C44, C47, C55, C30 (C meaning UHF channel).

I'm unsure if you can help as I don't think is is a Freeview problem but advice would be appreciated.
My post code is LE15 7DR and I'm using the Waltham tx.

I have a youview box connected to my TV via the HMDI cable as normal. I've also got a standard arial cable connected from the box as well for when I'm not using Youview, basically standard TV as the signal is routed directly through the box.

The problem is, while watching through the box (HMDI), I get intermittent quality/signal strength on some channels (e.g. 3 ITV, channal 4, channel 5 etc) but BBC is fine. Looking at the list of affected channels it appears to be all from Walthem Central (East). Watching through the standard standard arial connection, as described, is all fine. These problems seem only occur with bad weather, currently it's very windy with heavy rain showers.

I've tried BT but they are blaming Freeview so I'm trying to isolate the problem. Would a poorly aligned arial cause this?

So BT blaming Freeview, hmm, did they bother to check your predicted reception and/or make any suggestions, sounds not, hardly inspiring for anyone thinking of have BT TV!

OK, lots of possibilities, so eliminating the easier things would be a good start.
Waltham isn't currently listed for Planned Engineering or have any faults that I can find currently listed.
To quickly mention a comment about your query on aerial alignment, yes possible, but as you haven't said where your aerial is, we'll come back to that. Rain can in any event have an effect on the received signals.

With your set-up as is, have a look in the TV and Youview box tuning sections and see what signal strength and quality figures are being given for each multiplex UHF channel, make a note of them.
In the order PSBs1-3, COMs4-7 the UHF channels for Waltham are C32, C34, C35, C29, C37, C31, C55. There's also a Local mux at Waltham on C41, check those are the ones you are tuned to.

Your predicted reception from Waltham is good for the PSBs - BBCA, D3&4, BBCB HD (the same for those 3) but not as good for the COM muxes - SDN, ArqA, ArqB & COM7 and poor/very variable for the Local mux if you can get it.
You might also get very variable PSB signals from Sutton Coldfield which could be within the beamwidth of your aerial or even from Belmont or Sandy Heath on side-lobes of your aerial (all different UHF channels of course).

Also see Channel listings for Industry Professionals | Freeview for which programmes are on which multiplex.

Any significant differences between signal strength and quality for the PSB muxes certainly indicates a problem, I would be expecting D3&4/PSB2 to be lower from what you are reporting, and maybe your TV tuner is more sensitive than the Youview box which is why you don't have a problem on the TV direct.
HDMI leads have been known to cause interference, more commonly with C55 (COM7) but also others, so make sure your HDMI lead is well away from your aerial and any flyleads especially if the aerial and flyleads aren't high quality double screened types.

Plug the aerial lead direct into the TV and check if there's any significant differences with the signal & quality figures with what you get in the normal set-up.
If D3&4/PSB3 is still lower and the relative figures for the others are still the same, then we're looking at an aerial/reception or downlead problem as these checks should have eliminated a local connection or equipment interference problems.

If your aerial is in the loft then alignment can have a noticable effect (as indeed it could externally) due to things like a metal chimney, lead flashing, solar panels, party walls, water tanks and etc. You certainly don't want any of that lot in the signal path or in front of the aerial if at all possible.
Damaged downleads, poor connections, water ingress can also affect particular multiplexes as they can sometimes cause standing waves in the cables and attenuation of some frequencies but not necessarily all frequencies.

Externally, trees near the line of sight can sometimes cause multipath signals, especially when wet, but obviously an external aerial will give problems if there is water ingress into the connections. Aerial alignment could affect an individual multiplex more than others in some circumstances.

My aerial is attached to the chimney on the roof and is pointing towards the malvern transmitter. just in the last two weeks i have began to get interference on BBC NeWS, bbc1, bbc2 and bbc4 in the form of picture breakup and failed recordings on these channels. however, if i switch to their equivelant hd channels there is no problem. i am using a humax Freeview recorder box. when i check the channels or re search for the channels they appear to be coming via c44 from malvern. any help would be appreciated

COLIN ALLISON:

It's not a good idea to "search" / retune when you have pixellated signals. It means the signals are weak or have interference which may be due to transmitter maintenance or some weather conditions. Invariably you can lose correct tuning and have to repeat it when signals are normal, maybe having to try several times as you can't be certain when that may be!

C44 is the D3&4/PSB2 mux at Malvern.
Malvern''s channels are C41, C44, C47, C29, C31, C37 in the order PSBs1-3, COMs4-6.

The Malvern transmitter hasn't had any Planned Engineering recently and I can't find any recent faults listed either. It's quite likely that you problem may have been weather related creating interference from more distant transmitters. There has been some sporadic Tropospheric Ducting around, see
Effect of tropospheric ducting on Freeview | RTIS for a simplistic explanation. It's been very variable, and can come and go quite quickly, sometimes last longer.

I would however check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction. Also check all you coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads can be a common problem, try swapping them. See what signal strengths (if any) and quality you are getting for the other multiplexes shown in your TV's tuning section, this might indicate potential issues with your aerial or downlead.
Aerial misalignments, problematic connections, water ingress etc. can seem to affect reception of just AN individual or several multiplexes.

Also check that you don't have any HDMI leads close to any aerial or flyleads, especially if the aerial and flyleads aren't high quality double screened types. HDMI is known to sometimes cause interference.

Is there any difference in the freeview boxes inside the Tv compared to a dedicated standalone box

Rob:

The simple answer is Yes, and there could be, but it depends on the reason for your question.

The differences between TVs, & the differences between boxes will all be variable depending on Model/Type and Brand. They could all have different signal sensitivity, different picture and sound quality.
As a general rule one might expect a TV set to to do better if it's a T2/HD tuner but you could get better quality from a Box (using an HDMI connection) depending on the Brand and if it has a T2/HD tuner. It might also depend on whether the TV has any up-scaling capability.

I'm afraid there do seem to be some bugs in the system. Some postcodes seem to work, others do not.

I agree: most main transmitters use horizontal polarisation whilst most smaller 'relay' transmitters use vertical polarisation. Vertically and horizontally polarised signals do not regularly interfere with each other. It is related to do with available frequencies and preventing interference between signals on similar frequencies as we see in the reference in https://fpformacionprofesional.com/, please check if you need it.
