Roof aerial points to Crystal palace. Location Stansted Mountfitchet
Would Sandy Heath give me a good picture?
Last week we had the pleasure of receiving ITV Anglia News instead of London! Reverted unfortunately over the weekend.
Why did this happen?

Steve's: mapS's Freeview map terrainS's terrain plot wavesS's frequency data S's Freeview Detailed Coverage
Steve: Looking around your road using Google Streetview there are quite a few talls trees which could be an issue. I can't see a single aerial on Sandy Heath, but a few have an aerial on Sudbury and one on Crystal Palace.
This perhaps suggests that the trees put paid to reception from Sandy Heath. Maybe your neighbours could advise as to how good their Sudbury reception is.
If you do go for Sandy Heath, then its Public Service (PSB) channels are Group A (first third of the band) and Commercial (COM) channels are Group B (middle third of the band). Thus, if your current aerial is a Group A one (which all of Crystal Palace's channels are before and after switchover), then it will work for Sandy Heath's PSBs.
If you go for Sudbury, then its PSBs are Group B and its COMs are Group C/D (top third of the band).
Wideband aerials trade sensitivity within each Group with increase sensitivity across the whole band, particularly being less so on Group A channels. See here:
Gain (curves), Again
In summary:
- Crystal Palace would appear to be your best bet from a signal strength point of view on all channels. However, it gives you London programming.
- Sandy Heath may be blocked by trees; you can perhaps see much better whether this is the case than Streetview shows.
- From what I can see, no one has an aerial on Sandy Heath. You could perhaps take a walk around your area and see if this is the case, perhaps identifying why it may be the case (e.g. trees).
- Whilst the Digital UK Predictor suggests that reception of Sudbury's PSBs will be "poor" and its COMs "variable", there are a number of aerials on it. The predictor's calculation of poor PSBs could be as a result of another transmitter using the same channels. Aerials have greater rejection of unwanted signals in some directions than in others, so this may be less of an issue, depending on that factor.
- For full service from Sandy Heath or Sudbury, Group aerials that cover a third of the band will not be sufficient. Either a single wideband aerial (perhaps a less favourable option for Sandy Heath with its PSBs being Group A) or two Group aerials diplexed (combined) together into one downlead. Or for Sudbury, a single Group E aerial (top two thirds of band).
- If you do go for Sudbury, then its COMs are on low power until 27th June, so will probably be unavailable at your location until then.
- Sandy Heath's SDN multiplex (ITV3 etc) is on low power until 9th May, so may be unavailable until then.

Steve: I hope that I've gone in at too high a level. If I have, let me know.
If you are considering getting in a professional rigger, then can help to have an appreciation of the potential issues.
