The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

Hi there , I retuned on the 27th June and got all 122 channels . Switched on 30th June and now cant get Arq A , Arq B and group A .
Just like before the switchover .
I have a brand new aerial and wiring and as it all worked on the 27th It must be a problem at Sudbury I presume

Jack: A television which is described as HD Ready can display HD pictures, but does not have the means to receive the HD signals over the air. That means that it will require a separate HD receiver, whether this be a terrestrial one (Freeview) or a satellite one (e.g. Sky HD or Freesat HD). Click the words "HD Ready" for an explanation.
Only sets labelled as Freeview HD and/or with DVB-T2 in their specifications will receive HD as that is the standard that is used for it in this country. DVB-T is the standard used for standard definition terrestrial broadcasts, so a set capable of receiving standard and high definitions will have a DVB-T and DVB-T2 tuner in.
As for the question of getting all the Freeview channels, the UK has a two-tier terrestrial transmitter network. The biggest 81 transmitters carry the full service (they are the biggest by viewer population). There are over 1,000 small "filler-in" relays, including Newhaven, that carry only Public Service Broadcaster channels (PSBs).
The 81 full service ones carry both the PSBs and the Commercial multiplexes (COMs). This provides the COMs with coverage of 90% of the population. The cost to the Commercial broadcasters of transmitting from the 1,000 or so sites would roughly double their cost of transmission whilst only adding about 8.5% of the population to their potential viewer-bases. Because they operate on a profit making basis, by selling advertising which they show to as many viewers as possible which aquire at least possible cost, they aren't interested in transmitting from the small sites. The Commercial broadcasters have no "Public Service" obligation.
All transmitters broadcast the four HD services of BBC One HD, BBC HD, ITV1 HD and Channel 4 HD, as these are on a PSB multiplex.
For a list of services by multiplex, see here:
DMOL Post-DSO Multiplex Channel Allocations
That page shows the six multiplexes (each is a separate signal). All six are available from the 81 full service transmitters with the remaining being PSB-only.
Wideband aerials are needed in some cases because frequencies used by particular transmitters are spread out across the band and aren't all within the same portion used for the former analogue services.
Thus, in order to get the COMs, you will need to receive them from Heathfield or possibly Whitehawk Hill (adjacent to Brighton Racecourse) or Rowridge (on the Isle of Wight and is the main transmitter serving a portion of the south coast).
The predictor does not say what you "will" receive; it should be used merely as a guide. What you can receive depends on many factors and an on-site assessment can only really decide either way. Local obstructions such as buildings and trees can be an issue.
Whilst you don't have line of sight to Heathfield, owing to Beddingham Hill, it doesn't look to be too much of an issue.
I had a look on Streetview to see if there were any clues. I couldn't spot any aerials except for one on Glynn Road which is visible from your cul-de-sac. This one is pointing at Heathfield, so may give rise to the hope that you can receive from it.

Jack: On checking your reception possibilities you are quite correct insomuch that as far as "reliable" reception is concerned it will only be possible from the Newhaven PSB transmitter which offers a limited number of channels
However as you presently have a Sky+ set up I would not hesitate in recommending that you go along the Freesat line, as if you purchase a Freesat HD twin tuner recording device (PVR) that would take full advantage of the twin inputs you have from the dish.

Jack: This is a link for the type of device referred to, other cheaper types are available but up to a point you get what you pay for, and the device in the link is one of quality.

Jack: I take back what I said about the aerial I saw being on Heathfield. It is in fact on Rowridge, as is another on Glynn Road.
If you decide to try and receive from Rowridge, then I suggest that you use a Group A aerial and not a wideband yagi as their gain is lower on Group A channels, which is what Rowridge uses.
See here:
Rowridge Transmitter
Also, for best reception from Rowridge, have the aerial vertical rather than horizontal.

Yes we are now getting ArqB fine. So looks like new aerial is on the cards.

Help please.
Here at Aldeburgh, where we used to occasionally get Challenge, Pick and Yesterday on their very low power, and ITV 3 on 14 kw, now, since 24 June, we have lost numerous channels. No change of high gain aerial, but now only 21 tv channels. I find channels on the mux on ch 41, and 44, but nothing else, although it hovers on 56 but finds nothing. As regards channels on the box itself, we skip from 9 to 13, 14, then to 28, then 33, then blank to 70. I cannot understand how a change to better channels for various muxes, and high power, has resulted in this terrible outcome.
