Woodbridge Thank you gentlemen. The issue of aerials is quite confusing. If you go to ATV aerials site, they say the opposite, that a low gain aerial with wide acceptance angle plus booster is a poor substitute for a high gain aerial. But they do like log periodic, in areas of good signal strength. It also seems to be that boosters can do more harm than good on digital.Nick: I do not believe that jb38 has implied that a lower gain aerial plus booster is a "substitute" for a high gain aerial. He has said that a lower gain aerial plus booster can be better in difficult non-light-of-sight situations.
That does not mean that high gain antennas don't have their uses. What ATV is probably saying is that a low gain antenna plus booster is NOT the equivalent of a high gain antenna without booster. NickWednesday 25 April 2012 11:50PM
Nick: Thanks Dave. What part does non line of sight play though? Nick: Quite a lot.
Think of car headlights a night when they are coming towards you over the brow of a hill. Before they get over the brow, you do not have direct line of sight. You can see the growing mass of light above the horizon (which is the highest point).
Now imagine that the light is a signal you are trying to receive.
I believe that what jb38 is saying, is that it is best to use a low gain/wide acceptance aerial to collect this "mass of light" rather than a high gain/narrow acceptance one.
Read ATV's page on amplifiers:
Television Aerial Boosters / Amplifiers, Splitters, Diplexers & Triplexers
Amplification is fine so long as you are amplifying a small good quality signal. If you amplify a small poor quality signal then you will end up with a large poor quality signal.
Because a high gain aerial has a narrow range of acceptance, it is imperative for the signal to be "good" quality along that narrow path where it is most sensitive. If it's not, then all you'll have is a poor quality signal.
The suggestion that a low gain antenna is better means that the signal that it is "collecting" is over a wider surface area of the aerial. Therefore, if "some" of that is "poor" but most is "good", the "good" will win through and therefore the signal carried down the aerial lead will be "good".
Or to think of it another way, consider the high gain antenna with small acceptance angle. Let's suppose that "most" of that angle is filled with a signal that is "poor". The signal carried down the lead will therefore be "poor". Now imagine replacing the high gain aerial with a low gain one that has a wider acceptance angle. Because the "poor" bit is spread over much smaller proportion of the acceptance angle, it therefore follows that the signal from the aerial is better (albeit perhaps of smaller magnitude).
jb38, am I on the right lines? NickThursday 26 April 2012 7:48AM
Thank you Dave for your trouble in giving such a full answer.
Now let me throw another thing into the pot. I have recently been posting questions on the Tac site as I believe the mast height has been increased and coverage extended since going digital. I was advised that Sud is still my better option as at 10m it is technically line of site. So in theory the answer would be to get a good set of binoculars and see if it is!John ChambersThursday 26 April 2012 4:46PM
Witham Why has there no official information about channels I had prior to November 2011 not coming back until 27 June?
I only found out by speaking to a gentlemen from Freeview and had it confirmed via this website.
John Chambers: Indeed.
The only thing I can suggest to you in the mean time is that, if your receiver allows manual tuning, you do so to UHF channel 28. This is the equivalent service from Crystal Palace and has been available since 18th April when it switched. You may be lucky and be able to pick this up to some degree until Sudbury's power goes up. jb38Thursday 26 April 2012 9:35PM
Nick / Dave Lindsay: Regarding the illustrations of the gain curves for the various aerials seen on ATV's site and the comments / recommendations made about their use, it should be appreciated that these are made in general terms irrespective of whether the aerial is used for analogue or digital reception, and my comment is not at variance with what's been said on the site (one of the few I have always approved of) but is simply a qualification concerning the possible snags that may crop up if using a particular type of aerial for digital reception under certain difficult conditions, namely non line-of-site and where the problem is not one caused by excessive distances.
Reception issues do not generally occur in very near to open line-of-site situations even at considerable distances, and so a high gain multi-element aerial can be of benefit there as it can be effectively focused to where the mast is located, however in circumstances such as completely non line-of-site then any signals received obviously has to have a reflective element attached to them or they could not be received in the first place, but because of being received that way they nearly always have an erratic and in many cases rapidly fluctuating element attached to them as is witnessed by the quality frequently being observed to dive up and down, and although this type of problem is mostly caused by trees it can also be caused by numerous other intermittently occurring reasons like the signal path being near to, or even crossing a main highway frequented by high sided vehicles.
Unlike the stability of analogue reception, the critical characteristics of digital reception cannot cope with this sort of thing resulting in the quality taking a dive, and so if an aerial with a narrow acceptance angle is used under these sort of conditions then any fluctuations on the signals being received will have much more of an effect that it would do in a lower gain wider acceptance angle aerial, and with this resulting in a much higher level of picture glitching being noticed.
The other problem with the use of a tight acceptance angle aerial in these type circumstances being that its alignment doesnt always hold for long, and so its case of peaking it for quality every month or so dependant on weather related issues.
Regret delay in replying, but I was held up by an unexpected snag at at a job today.
jb38: Thanks for the interesting insight.
The topic is coming clearer to me.
I can see how trees and passing traffic may be an issue where they pass over the brow of the hill. The brow being perminantly flat means no change in the path of the signal. Moving trees or traffic effectively acts to vary the "brow" of the hill so that it is not flat and crucially is always varying.
What about polarisation of signals? Are vertical ones affected more than horizontal ones or vice versa? NickThursday 26 April 2012 10:58PM
Dave and JB, you are being very helpful, thanks.
Another one. A booster is less use the further from the aerial it is placed as it amplifies a lesser signal the further along the coax it is until putting it behind the set appears to do nothing.
Why then do they put them half way or more down the pole, rather than, for instance, behind the reflector?Nick: This page, also from Megalithia (the website that does the prediction for how good your line of sight is):
Mo' Betta - abuse of DTT TV booster amplifiers
Boosters should be fitted before loss:
- before a length of cable whose loss is too great for the signal to stand (this may be useful where there is a good quality but low amplitude signal), or;
- before a signal is split (so as to counteract the loss of splitting the signal). jb38Thursday 26 April 2012 11:18PM
Dave Lindsay: I have always found that vertically polarised signals are generally better all round, although I do have to admit that most of my non domestic involvement has always been with FM and AM equipments and as such the effect I referred to would not be applicable to these modes, as it only really applies to the reception of digital TV signals as anything of a digital commercial nature doesn't operate on the same hit and miss basis as domestic TV.
That said though, now that Rowridge transmits in both polarities I would love a chance to carry out some tests at various points around the area, but by it being a bit distant to me will just need to be content and wait to see what kind of complaints are being made from the area and with the type aerials being used by the complainants.
NickThursday 26 April 2012 11:28PM
Nick: Dave, thanks re booster. Surely this reinforces the idea that it be placed 6 inches from the dipole rather than more than six feet?
Incidentally, I am trying a crafty move as I don't want to take the aerial down if the signal should be too strong. I have a behind the set box which does nothing there but seems to have three transistors which to me indicates it is high gain. I have housed the amplification part in a plastic box, intending to put it near the dipole, dispensed with the transformer, replaced it with one which offers 6, 7and a half, 9 0r 12 volts, and connected the two via a length of phone cable, and reduce the voltage if gain is too high. I have tried this with analogue Dover, where I am well out of range.NickThursday 26 April 2012 11:45PM
Norm, I am looking at the info at the top of the page that says various commercial channels from Sudbury carry programming/local news as from Meridian rather than Anglia..NickThursday 26 April 2012 11:54PM
I was wondering why some of my comments re Sudbury seemed to have disappeared and have just realised UK free tv has two sites for the transmitter. Wonder why. NickThursday 26 April 2012 11:56PM
Dave, if you happen to have a phone a friend who knows about DAB I would be grateful, have posted some qs on the Aldeburgh tv and dig radio pages without success.Nick: I have just found this Arqiva document on a prospective Suffolk DAB multiplex which does list Aldeburgh:
http://stakeholders.ofcom….pdf
Thinking about the intended coverage area of the Suffolk multiplex (Suffolk!), *relatively* speaking the area left out (uncovered) if Aldeburgh wasn't used would be greater (relatively) than with the national multiplex.
There are more Digital One transmitters coming on air. I know that Scarborough was added a few years back. Due to the terrain, the only reliable transmitter for TV and radio is its own.
I have to say though Nick, from what I can see, you aren't in a valley of which there are a few in the area and of which I assume those living in will have no option but to rely on Aldeburgh. For that reason, I get the feeling that, whilst it is unfair that there are those who cannot get commercial/independent DAB stations, you may be in an area where you can. And if you add to that the fact that you intend to receive at roof level, then your chances must be even greater! NickFriday 27 April 2012 7:18AM
Thanks Dave.
I have experimented with a DAB dipole on a long pole, but only on the shed, aerial about upstairs window height. I can get the radio to log on to some commercial channels, but not strong enough to hear, so hopefully at roof height it might work. I would like to use a directional aerial, but don't know where to point it as the signals are probably either from Manningtree or Mendlesham, but as on same frequency, don't know which. If you have any idea why the commercial channels are on lower power than the BBC, I would be interested to know.
What do you think of a booster 6 inches from dipole for tv?jb38Friday 27 April 2012 7:52AM
Nick: Regarding the booster you are referring to what gain do you see it rated as having? and as regards to their use, the only reason they are recommended to be installed as near to the aerial as possible is because it limits the chances of any electrical based interference being amplified if picked up in the cable before it enters to the booster, as obviously the amplifier would boost the interference as well as the signal.
Of course the other reason is, that if the signal is at a higher level before passing down the coax then the ratio of the signal to any possible interference will be greater thereby limiting its effect.
On the other point regarding what you are intending doing with the booster, its not advisable to have it in a plastic casing as that doesn't offer any screening, as even these relatively low cost high gain (13db+ boosters that you can get nowadays made by Vision and others are all contained within a metal casing, and these little devices are excellent.
Also, I don't want to put a damper on your variable voltage idea, but dependant on circuitry used you would most likely find that the variation in gain would be virtually negligible between these voltages as it would have to come down to about 3 volts or so before much of an effect would be noticed.NickFriday 27 April 2012 11:36PM
Thanks JB. It is already in a metal casing, I am just keeping the rain off. I don't know its gain, but it gives the same benefit as a 28db one I have to analogue Dover. The gain does decrease with each drop in voltage, till it does nothing at 3v.
Would you recommend immediately behind the reflector? I only see them half way down the mast.KMJ,DerbySaturday 28 April 2012 12:11AM
Nick: Is there any sign of a signal from Oulton on Norwich 11B?jb38Saturday 28 April 2012 12:23AM
Nick: I can assure you that it doesn't matter that much whether its behind the reflector or about 8 feet or so under the mast, as I can guarantee you that it will not in reality make any difference.
Its just a pity that it doesn't have any names on it though as otherwise I would have checked on its spec, and especially why it seemingly responds so quickly to slight voltage reductions as most dont.
NickSaturday 28 April 2012 8:08AM
No, KMJ, nothing from Oulton. Do you know why the local and commercial stations are on lower power than the main BBC transmitters from the same site? It seems they want to make things as difficult as they can with coverage. At IP12, they don't provide DAB at all.
JB. It responds instantly to the voltage drop. Perhaps the length of phone cable reduces the voltage a bit.
Perhaps with Dover, where the signal is barely detectable, having the booster immediately behind the reflector captures what little there is, whereas with Sudbury it matters less as there is a good signal to start with. I had to have some means of reducing the Dover signal as it is variable. Most times it is snowy, even with the booster, others it is very strong.Thanks for the tips Dave, I went old school and looked up, the aerial has snapped of the mast and is only hanginging on by the cable..It not a particularly old aerial, probably 5 years max, I guess the recent winds have done for it. Brian O'Keefe: Oh dear. If you intend to fix it yourself, then I recommend looking at www.aerialsandtv.com JAMES JOHNSONSaturday 28 April 2012 8:31PM

Hello. Before October 2012, I was receiving all Freeview channels. Since then, I lost channels 12, 15,18, and 24.
I have tried retuning, but no success. My aerial is on my roof.
Please tell me when you will be increasing the power in that transmitter at Sudbury? Thank you.Norm De PlumeSunday 29 April 2012 8:28AM
James, this isn't a website run by any authority, it is independently run. However, the answer to your question is that power on Sudbury is increasing again on 27th June. At the same time as the power increase, ArqB (the multiplex with those channels) will move from its temporary frequency of C63 to the final frequency of C56, which also is a lot easier to receive.
In the meantime, if you haven't already done so, replace the leads from the wall to the TV/STB etc with quality replacements. It may sound strange, but the signal lost through bad cables is often equivalent to the signal boost you would get from an aerial amplifier.
You can make cables yourself with nothing more complicated than a penknife, pliers and a small screwdriver. All of the cable and connectors are easily available from suppliers like Screwfix or Maplin. Make sure that you use double screened cable, something like the SLX PF100 which is available in white.KMJ,DerbySunday 29 April 2012 8:42PM
Nick: There was a requirement by Ofcom for the local muxes to be planned in such a way that the signal did not stray out of the intended coverage area! As radio waves do not respect county boundaries this was rather impractical, resulting in under-powered signals in some instances, whilst in others listeners are (fortunately) able to enjoy reception miles outside the target area. The D1 national mux has tended to target the areas of largest population and major roads, whilst the BBC is now trying to give good general coverage in preparation for the suggested FM switch-off. The latest Ofcom plans for local services allow for more comprehensive coverage in unserved areas to match the current FM service areas. I will be interested to see if the coverage of existing local muxes is extended to match the FM service areas of all the BBC local radio stations.NickMonday 30 April 2012 7:21AM
Thanks KMJ. I wondered why there were so many DAB transmitter, but not enough, whereas FM uses much higher power with far fewer transmitters. Daft rules again. They will have to get their act together before switching off FM.g sawyerTuesday 1 May 2012 11:21PM
please can you tell me how a can't get the yesterday channel as stated from you that all channels are on full power i live 6 MILES from you and everybody i have asked they can.t GET the yesterday programe
grahamDaleWednesday 2 May 2012 9:46PM
g sawyer : assuming you are on Sudbury, over half of the channels are not on full power until June. Yesterday is one of those on ArqB on CH63 which most people cannot pick up properly since its switch from CH50 in November. Digital TV refused to accept this had caused a problem at the time, and eventually most people, like me, got fed up with complaining and are reluctantly sitting tight until June.DaleWednesday 2 May 2012 9:49PM
That should read Digital UK, of course. Or "I see no ships" as I prefer to think of them ...Norm De PlumeThursday 3 May 2012 6:11AM
G Sawyer, as Dale says, the channel that is used for Yesterday is operating at around 1/100th of the main channels. Not only that, but it is in a part of the frequency range that is right at the edge of receivability for most people's equipment. This is not a good combination and if you look back through this part of the forum you will see that the majority of recent problems are from people unable to receive Film4, Yesterday etc., all of which are carried on the same channel. This situation will improve in late June when there is a final retune which will move this channel to a better part of the band and will also increase the power to the same level as the others.
You haven't given your location but you said that you live 6 miles from something/someone. If you happen to live 6 miles from the Sudbury transmitter, then you probably have a different problem called desensitisation. In this situation, the high level of signal received from the more powerful stations swamps the smaller signals from channels like ArqB (the Yesterday channel). If that is the case, the solution is typically to successively cut down (or attenuate) the signal until you hopefully reach a sweet-spot and all channels can be received cleanly. Have a look at the page

John: It's due to happen on 27th June when a retune will be necessary for all Commercial channels as they all change UHF channels. Richard OwenMonday 14 May 2012 8:38PM
Halstead After not being able to receive channel 54 since November ,except during strong winds ,or high pressure it suddenly returns ,I think as soon as the leafs came on the trees ! I live near Halstead 8nm from Tx at Sudbury ,CO9 1RB! is my answer correct ? Wideband outside arial.Norm De PlumeTuesday 15 May 2012 7:24AM
Richard Owen - you are likely to be suffering from too much signal. If you check out the post 2 above yours that situation is covered at the bottom.
It should get a lot better on 27th June when all the signals will be broadcast at the same level.jillSunday 20 May 2012 9:31PM
IN the last 2 weeks we have pretty much lost the ITV4/Yesterday/film 4 group with total breakup of the picture. Up to this time we have had no problem at all. Based in Coggeshall we receive from the Sudbury transmitter. Any enlightenment on why this has happened all of a sudden. As I understood it the last work was back in November and things were fine after that. I have done several retunes to no avail.Norm De PlumeMonday 21 May 2012 7:32AM
@Jill - its surprisingly straightforward, there haven't been enough leaves on the trees since November to affect the signal. However, in the last couple of weeks, the sap has risen and the leaves have sprouted. Up until now, your signal has been borderline, but the effect of the water in the trees and the leaves has been to push the signal down just that little further and your signal is now at too low a level to receive the weakest signals, i.e. ITV4 etc.
The good news is that the signal will be massively boosted on 27th June as a result of the last stage of the digital switchover for Sudbury, and you should then have the same quality of signal as you do for BBC1.jillMonday 21 May 2012 11:23AM
Tx guysJimFMonday 21 May 2012 11:57AM
jill: It could be trees, but it could also be a dodgy flylead (from wall socket to TV - try a different lead), or possibly water in the coax cable from the aerial (Arq B MUX would be affected first since that's the highest frequency - until 27th June when Arq A MUX will be the highest frequency).Norm De PlumeTuesday 22 May 2012 7:17AM
Jill - thanks for the reply, you'd be amazed how many people pop in, ask a question and are never heard from again, so your reply is appreciated :)
With only a month to go to the power increase, there's not a lot of point looking at more complicated checks, but JimF's suggestion about the cable is well worth considering - replacing a low quality cable from the wall to the TV with a good quality one can make all the difference in your situation.
If you haven't got a good spare cable, I would advise against buying the typical DIY store rubbish. Instead, have a chat with a friendly aerial installer and ask them to make you up a lead with some decent quality double screened cable. Alternatively, satcure stock them -

Halstead Yes ,thanks Norm , its without doubt the leaves,the PSB multiplex signals ,strength & quality are down, allowing the tv & recorder receivers to re-sensitisation so I can now get Sky News again ! Yippee ! Since I got a wideband aeriel in 2006 not had any probs until they buggered about with the tx ,for some reason in late Nov .Rich Halstead jillWednesday 23 May 2012 12:33PM
Tx guys, the aerial system and cables were all set up last year by Bennets a very reputable aerial specialist in Colchester so Im guessing we just have to hang fire for the power upgrade in June. It is just literally the last few weeks where its all gone on those specific channels. I have recordings from March from the channels where everything was fine! #drums fingers and sighs deeply#NickSaturday 26 May 2012 4:45PM
Can anyone tell me why we have this page for questions on Sudbury? It is confusing as we already have one called freeview from Sudbury transmitter.KMJ,DerbySaturday 26 May 2012 11:04PM
Nick: Originally all transmitters offered an analogue service, usually on four or five channels. Each transmitter therefore had its own page dedicated to the analogue switch-off. Additionally there were 80 transmitters which offered a (usually) low power Freeview service. These transmitters had the "Freeview on the Sudbury TV transmitter" type pages to give details from the viewpoint of a digital household. Following DSO the analogue orientated pages are re-titled "digital TV transmitter" with details given for the replacement digital services, the Freeview orientated pages being similarly up-dated to show the current situation.Norm De PlumeSunday 27 May 2012 8:35AM
@John - The answer to your question is that power on Sudbury is increasing again on 27th June. At the same time as the power increase, ArqB (the multiplex with those channels) will move from its temporary frequency of C63 to the final frequency of C56, which also is a lot easier to receive.HeinzSunday 27 May 2012 3:58PM
I just had a TV repaired (well, if you can call a software upgrade a repair) by Andrews TV of Colchester (another very reputable company).
The job sheet states they'd updated the software and re-scanned for channels and yet all Arq B channels were missing when I got the set back - so even the professionals are still having difficulties!jb38Sunday 27 May 2012 5:56PM
Heinz: Purely out of interest I was wondering what model of TV you had this work carried out on?
Of course the other thing is, that if they re-scanned the TV it could well be the case that Andrews TV is not necessarily located in a best reception area as far as picking up the commercial transmitters are concerned, especially the exceptionally low powered ArqB Ch50 that doesn't increase in power until June 27th.
That said though, "if" you see EPG12 (Yesterday) on the programme guide then they are receiving it and you are not, however if you do not see EPG12 then they haven't received it either, and so you could try retuning the TV yourself just in case you are in a better spot.
