Freeview reception at G81 3EF


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.

Of course some locations are exposed to some atrocious winter weather, however a good professional installer (CAI approved) should be able to provide an installation that lasts more than a winter or two!
That said, using indoor aerials can be fraught with issues, it depends on how far you are from the transmitter(s) and whether you can get a "line-of-sight".

We need a full postcode to look at the predicted reception in your locale and which transmitter(s) and multiplexes you might receive.

If you have a "smart" TV, why would you need a "Freeview" box? What make and model is the TV?

Lost all Freeview channels due to no signal on TV screen on 16/11 and still no signal 19/11.

As you haven't provided a full postcode, it's not possible to know whether your predicted reception could be marginal under normal circumstances in your locale, and whether you'd be using the Nottingham transmitter or the Waltham one, both of which have been on Planned engineering this last week.

Two of us have already responded to your post on the Nottingham transmitter page. Have you followed the advice about NOT retuning or what to do if you already have?
Some information about your aerial installation would also be helpful and which way the aerial is pointing and whether the rods (or squashed Xs) are horizontal or vertical.

It might also be an idea if you check all your coax connections behind your TV etc. If you have weak signals due to the engineering then bad connections could mean you have no signal.

I have a loft aerial and TV reception has been ok but has deteriorated such that we're unable to pick up some T V channels recently . It's an intermittent problem but please can you offer any advice?

Norman Ainsworth: We need a full postcode to be able to see which transmitter the predicted signal strength at your location. Have you checked in the loft that the aerial is still attached and pointing towards the transmitter? If it's been up there a long time it's possible that the fixings have come loose and the aerial may have moved or fallen down.

Hi, I have low quality on HD channels 10 to 40% depending on channel this causes pixilating on the screen at times. 100% on strength on HD channels. All SD channels are 100% on Quality and Strength.
Are HD channels broadcasting on low power ??????

My Ariel is on the side of our house chimney and I use and amplifier tried different amplifiers still the same low quality on HD channels. NN7 1AE Lodge Road Little Houghton.

Did a search and apparently HD channels from this >>>> COM7 HD 55 <<<<< at Sandy Heath are not guaranteed in my area NN7 1AE any chance this is going to change.

Andy Falls:

When you say you have tried "everything", does that include a retune?
Which way (rough compass bearing) does your aerial point and are the aerial rods (or squashed Xs) horizontal or vertical?
There are several transmitters that could be received at your postcode. You should get almost perfect reception from the Angus transmitter to the ENE of you.
Have you checked that your aerial looks intact and is still pointing correctly?
Also check your downlead is secure and not flapping in the wind and that the coax looks undamaged and check all connections and coax plugs behind your TV.

MR P Mayhew:

Well, the disappointing news for you is that it is going to change, BUT COM7 was only ever a temporary lower power multiplex and is due to close by the end of June 2022. There's been no announcements yet about what will happen to any of the channels on the multiplex. The main HD channels 101-105 are on the BBCB HD multiplex and that transmits at the same power as the other 2 main PSB mutliplexes so you should not be having any problems with them, your post is unclear as to whether you do.

Now if your aerial is pointing towards Sandy Heath (Anglia region), Bearing 104 degrees (almost ESE) with the rods (or squashed Xs) horizontal then the Freeview and BBC predictions are quite reasonable - variable reception which means it should be ok most of the time. Whereas if you aerial were pointing due N at the Waltham transmitter (Central East) you're predicted to get very poor reception of ANY of the COM multiplexes.

See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex. (Note - there is no Local multiplex at Sandy Heath but there is a low power one at Madingley which is further away - you are not predicted to receive it).

A first check you could do is make sure you don't have any HDMI leads close to any aerial or flylead cables especially if the latter aren't double screened coax. HDMI has been known to cause interference especially to UHF C55 COM7.

If you are also having problems with the main HD channels 101-105, then this could be due to having too much signal as you've got 100% signal on all the other multiplexes. Apart from pixellation and sound breakup, the quality figure tends to reduce and weaker multiplexes will probably suffer first. If you have severe overload, the strength figure can appear to reduce as well when in fact it hasn't. If your amplifier(s) have a gain control, then try turning it down a shade so that the signal isn't 100% on the multiplexes.

If the amplifiers are splitters as well (feeding more than one set), try swapping outputs to see if anything changes but It's less likely that individual outputs go down, the whole amp may however. Try the aerial direct to one set without any amp/splitter and see what strength and quality figures you get for each multiplex.

Also just check all your coax plugs and connections, I assume you've checked your aerial looks intact and is still pointing correctly and that the downlead isn't flapping in the wind. Make sure there is no corrosion or water in the downlead at the plug end.

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.
