david mitchell: Digital UK show COM7 & COM8 as being available from Sandy Heath until at least 2020. Retuning was a bad idea as you've now deleted the tuning data for these multiplexes which were previously tuned correctly. If you've had a recent issue with weak signal then you may well have a fault somewhere in your aerial system, with COM7 & COM8 being the worst affected due to them being broadcast at much lower power. If you provide a full postcode we can see the predicted signal strength at your location, which may help someone offer further advice.

Hello this isn't realated to Sandy Heath but it is my region.

My Freesat box has 100% quality and 76% Signal strength but last night the channel yesterday and Drama and a few others kept dropping out and saying no signal and as far as I know there was no weather problems.
I've had issues with heavy rain before but never when it's perfectly clear.
What is the issue with my freesat?
Kind regards.

Ian: Have you checked for any loose or damaged cables or connections behind your TV and Freesat box? Check for any signs of damage to the cables between your box and dish (as far as you can safely access).

Ian it can be that your dish has shifted slightly . It still may read "strong signal " if it is picking up the wrong satellite . Also It can be the LNB (signal head) going bad and generating "noise".

Hi,

I have lost all com7 and com8 channels from Sandy Heath, anyone else? I have been getting good reception from Sandy Heath for over 10 years but now no com7 or com8 on any Freeview device in my home.
Postcode is PE14 7EZ. I already know that this is not the nearest / best transmitter but has been solid for over 10 years now. What has changed recently?

Thanks.

Stephen Hopps:

As you may be aware (you had a retune event summer last year) as part of the 700Mhz clearance, multiplexes are changing UHF channel. Part of this change involves COMs 7&8 becoming SFNs (Single frequency Networks) meaning Transmitters share the same uhf channel. Unfortunately this means some locations will be getting interference from one of them. It's also possible that this may vary due to weather conditions - there's a large High pressure system present at the moment which means some UHF signals can travel further than normal causing interference.

As you already know Sandy Heath is not the best transmitter but especially for COMs 7&8 at your location. Presumably you want Anglia region rather than Yorkshire. If you look at DigitalUK's coverage checker for your postcode Digital UK - Coverage checker (put your postcode in the box, ensure Detailed view is ticked & click Go - or click the link at the bottom of your posts - digitaluk trade) then you can see that it's also going to get worse later this year and early next year with further changes taking place around the country as well as some at Sandy Heath.

Belmont should give you the most reliable reception of all Muxes BUT this is Yorkshire region.
If you continue to want Anglia then Tacolneston may give you good coverage over all the multiplexes being predicted as only slightly worse on some (BBCA & D3&4) than Sandy Heath.

Changing transmitter will obviously require a shift in Aerial position and depending on whether you have a Group A or T/Wideband aerial may need an aerial change to Group T/Wideband.

If you don't have Cable or Satellite, you may be eligible for help with a new aerial, see Important changes to Freeview TV signals | Freeview

HTH.

Perhaps should have mentioned that Tacolneston may give you slightly different regional news for Anglia (you'll need to check the latest situation).

Any thanks for the replies, i'll look into getting the aerial re-positioned. I'm guessing a tv signal booster would have little or no effect?

Thanks again

Stephen Hopps:

Depending on what your current signal strength is, a booster could actually make matters worse!

The information given on the Digital UK Coverage Checker for your location (see Coverage Checker - Detailed View suggests thatBelmont is the better bet, with Waltham, Tacolnston and Sandy Heath either very poor to useless. The signals from Belmont will provide decent reception, but will include Yorkshire services rather than East Midlands or East Anglia.

Belmont needs a wideband aerial for full reception.

Strange how we interpret things differently MikeP.
Stephen hopps was complaining about the loss of reception of COMs 7&8 and Belmont will not be the best from that point of view after the end of this year !!
Waltham looks indeed as though it would be totally useless which is why I never mentioned it, whereas Tacolneston is predicted to give very similar reception to Sandy Heath for the other muxes BUT with more reliable reception of COMs 7&8 and it's still Anglia which I would guess is the preferred region.

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.
