By providing a full postcode (such as W1A 1AA), national grid reference (for example SE123456) or latitude, longitude pair (like 54, -0.5) this page will provide a map, terrain plot and detailed information of the location showing the UK and RoI television transmitters that it is possible you receive Freeview, Freeview HD, Youview, BT TV and Saorview from.
 

(Don't know your postcode? Find it at Post Office Postcode finder).

UK Free TV uniquely shows you transmitter coverage maps, aerial to transmitter terrain plots, the closest 10 mobile phone masts (for possible 4G-at-800 interference) as well as tabulated information (sorted by direction, by received signal strength, by frequency, by service names or by transmitter name).

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 https://www.freeview.co.uk/corporate/platform-management/channel-listings 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.

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.
