Paul Dicken:

I'm not really sure what Nick is on about. As MikeP has already said, Sudbury is predicted to give you very good reception for your postcode, whereas the Woodbridge repeater is predicted to be poor for your postcode due to the terrain but further more it only has the 3 PSB muxes, Sudbury is a main transmitter with all 6 muxes (it doesn't have and probably never will have COMs 7&8 - nor are they mentioned by DigitalUK - they will disappear in any event by 2022).
As for aerial, if your site is good, ie. no very local obstructions from trees or buildings and good height on your chimney then a log36 should do the job and has less wind resistance than the other choice which is a Yagi 18K.
If you are technically minded, a good site for information on TV aerials is

Also Dale Rumbold:
The changes in April-June 2019 that MikeP has mentioned are minor reception changes for the SDN and ArqA muxes. This will be due to other transmitters changing frequency and using the same UHF channels.

nick horrex: Are most of your Freeview boxes not DVB-T2 capable? Nothing will change before 2020 and I would guess things will only start to be phased in sometime around 2022 so you've bags of time to save some pennies ;)

I think the best advice to give Paul is to look at the type of nearby aerials and to where they point before deciding what transmitter to use and which aerial. Logs are just not good enough in that area, I used to live near there.
No, my freeview boxes show no signal on HD channels.
Can you give me more info on exactly will change next year, given that Sudbury will apparently continue to use channels 29,31, 37, 41 44 and 47?

I agree with Chris. The reception should be good . It may not help to check out other aerials in the area because they presumably were selected for the old Sudbury frequencies.

Hardy, I have seen few aerials for Sudbury in Woodbridge that are not high gain. Remember that in analogue days there was little point in using the Sudbury transmitter.

nick horrex:

DigitalUK's postcode checker - using the detailed view - is generally quite accurate and it's predictions are based on a 100m square for a given postcode (the number of houses covered by a postcode will vary from postcode to postcode). Looking at the local terrain using the tool available on this site, Paul Dicken's postcode has a very local hill between him and the Woodbridge repeater which is why prediction for that is very poor to non-existent reception, whereas there is line of sight to Sudbury.

Without looking at an OS map (for which I don't have time) I don't know how many hills there are in that area but as I'm sure you know, "high gain" aerials and stacked arrays were often used in analogue days to reduce or eliminate ghosting due to there greater directivity etc. I had precisely that problem where I used to live, whereas now with the digital signals a simple yagi does the job fine. In that particuler area a lot of houses are using a local repeater (with only the 6 + local muxes) whereas others use the main transmitter (all muxes) as digital reception is fine. Hence looking at (newish shiney - not old) immediately local aerials can only be used a rough guide to reception.

At Paul Dicken's postcode, if most of the new very local aerials are high gain, I'd probably consider the Yagi as the 3 PSB muxes at on UHF 41,44,47 although a Log36 will do a better job of rejecting impulse interference and only has slightly lower gain over the band.

As regards reception changes next year, if you look on DigitalUK at all the transmitters that are listed to change channels during April to June, you will find the information.

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.
