My high gain aerial can't get all the Freeview channels I expected
You need a "wideband" aerial rather than a high gain one (see all about aerials). Also, if you use a signal booster in the setup, this can cause problems with digital signals.
Can I suggest that you try the following:
1. Check that all the connectors are OK, in particular that there are no stray wires and that both the outer shield and inner wire are connected;
2. If you are using any signal boosters, turn them off;
3. Check to see if you have anything like a VCR connected via a UHF fly lead - sometimes these can changed to use channels such as 68.
4. If you have a wideband aerial, if you can try raising it up an additional metre;

If its Sutton Coldfield then your signal could be too strong which could be blocking your tuner, so for a test if you have access to a set top aerial connect into your TV and carry out a retune, if you get any results (no matter of what sort) then you will require to purchase a simple attenuator to place in line with your TV's aerial socket.

If by the way it does, then you should blank the channels stored out by scanning without the aerial connected, (or reset box) then before reconnecting the aerial start another auto-tune whilst watching the channels rise in the progress bar, and as soon as they pass about Ch35 reconnect the aerial and that will allow Wenvoe (or Mendip) to load. This said taking it that channels can be seen in the scanning progress bar, as in some boxes they cannot!
Freeview is terrestrial, and you should in theory be able to receive Wenvoe on that aerial, but this being totally dependant on whether or not you are in a screened location.P

Main PSB on 100Kw, COM's on 15Kw, which at your approximate distance of 36 miles away could well be difficult to receive, if not indeed impossible in areas such as yours.

Bill: You might be using a Freeview Light transmitter such as Kirkby Stephen - in which case replacing the aerial with a good quality Group A design, horizontally polarized and pointed at Caldbeck, may still produce good results. We need a full postcode to give a better answer.J

retuned my digi box today , and have have all channels but not the bbc's ie , BBC 1,2,3, and new24 , my postcode is nr30 2jd , great yarmouth area, as the screen said update i did ,my box worked fine untill with all channnels untill this update !!! if this is how change over is goiner work, what a pain, any1 know whats up M
Mike DimmickWednesday 9 November 2011 2:58PM
Check whether your box is on the list of equipment that is known not to work with 8K mode - 
http://www.digitaluk.co.u…ment . If you haven't retuned for a long time it could also have a problem with a larger Network Information Table - see http://www.digitaluk.co.u…tnit .
There are also some boxes which have a bug meaning they can't pick up transmissions in 8K mode when there is a negative frequency offset. The box will say 'T810' on its sticker somewhere. See 
Unofficial Vestel PVR Information (UK) - T810 Freeview Recorder and Unofficial Vestel PVR Information (UK) - Digital Switchover for more information on those.
Assuming you didn't have any trouble with BBC Two analogue before switchover, it's unlikely to be single-frequency interference. It could be that the total signal level received is now too large, though, now that the new Great Yarmouth transmitter has started up.
If the BBC channels are stored - after doing the full reset - but are too weak to actually use, your box may have tuned into Great Yarmouth rather than Tacolneston. There may be a working set up at 800 or so in the channel list. In that case, see Digital Region Overlap for thoughts on how to sort this out. M

The predictor shows a poor chance of getting reliable reception of the commercial muxes from Caldbeck. The PSB muxes offer a good chance of reliable reception. You could try it, but you might need to have a particularly large aerial installation.
If you do this, Digital UK show that your reception of the commercial multiplexes from Caldbeck will get worse after the Bilsdale transmitter switches over next September, for about a month before Divis (Northern Ireland) switches over. Once that's done, Caldbeck's commercial muxes can go up to their full output power, restoring roughly the same (still poor) prediction.
It may be easier to go with satellite, although Dave and Yesterday are both Sky-exclusive subscription channels at present.T

South ShieldsAngela: One possibility is that your TV decided to tune to the signals from the wrong transmitter. See this page for more info:
Digital Region Overlap | ukfree.tv - independent free digital TV advice
The simplest and most generic guidance I can give you to make sure it is tuned correctly is to re-scan with the aerial unplugged and then plug it when it gets to 25%. The objective here is to have the aerial unplugged when it's scanning the frequencies used by the transmitter you don't want. (DN31NJ) P

Keighleypaul: I guess that if you're receiving directly from Emley Moor in Keighley that you must be in the flats which means that the aerial is high up?
I think that the problem might be that your receiver has tuned to the signal from the Keighley or Keighley Town transmitters.
Is your aerial definately on Emley and not one of the Keighley transmitters? paul: You will probably have to resort to manual tuning. K

I have 2 aerials in my loft.
the first one is a knackered old thing with about 10 straight bars going across and leads downstairs. this gives perfect picture in the living room. The 2nd is a new fancy hi gain thing with many x-wing style bars going across and a couple of large reflector things on the back and goes to my bedroom and this gives me about 4 channels - bbc1, 2, 3 and cbbc. I also use a booster but without it i even lose the 4 channels.
How do I solve this bizarre problem? I've looked around a few websites but not solved anything. My best guess is something about a wideband aerial. Is a wideband aerial similar to my knackered old thing. do I need one of those? or do i have to wait til march next year and everything will instantly work out?
its not the tv (tunes perfectly downstairs) or cable i use (tried 3 cables) and cant run another lead off the original knackered old thing.Jonathan Ashenden,Southampton.Yer first loft aerial you described as a "knackered old thing" giving perfect reception in yer living room,is it coloured red at the tip,if so its a group A aerial and as Rowridge mast is currently and remaining a group A transmitter as such only group A aerials,never a group W wideband aerial should ever be fitted on a group A transmitter in poor reception or marginal areas within Rowridge itself.Which nicely comes to the point you mentioned about yer second loft aerial,which appears what you stated to be a newish X-Beam type aerial is it coloured black at the tip,then that will be a group W wideband aerial as such,and the wrong aerial come to that for a group A mast like Rowridge in a poor/marginal area.You do not need a group W wideband aerial as such on Rowridge,but only group A aerials.Look up the ATV (Aerials and Television) of Sheffield website,you will find that a group A Yagi 18A aerial,X-Beam XB16A for outdoor mounts or an X-Beam XB10A for loft mounts are recommended options in your locality. Jonathan Ashenden: I second Mark's suggestion to look at the ATV website for loads of information on aerials.
It is worth bearing in mind that when switchover has happened, the transmission power will be increased. This means that any improvements/changes you make to your aerial setup are only of benefit pre-switchover as you current one *might* work after switchover.
After switchover, Rowridge will broadcast horizontally and vertically (it only does the former now). You will be best advised to re-orientate your aerials to vertical after switchover so as to have the greatest chance of getting the commercial multiplexes as they will be on lower power horizontally than vertically.

I'll give update when it arrives.
Anyone want to buy a fancy wideband aerial?B
brianFriday 16 December 2011 6:27PM
The bedroom and kitchen recieve all channels full strength. The TV in the front room only receives small number of channels. I've swapped all cables, TVs, and booster ports and results are always the same. The channels I do receive in the living room TV (BBC1, BBC2, BBC3, BBC4, ITV3, Pick, yest, Film4) all have 100 signal strenth and quality. Can anyone help?? M

JanakenSunday 18 December 2011 4:21PM
After checking the connections, the cause of this was because the wire in the wall plate was coming into contact with metal casing, insulating the wires resolved the problem. J

Ian Fellows: Ripponden is a low power relay that does not broadcast the commercial multiplexes (COMs). The reason for this is because the COMs broadcast from 80-odd of the most lucrative transmitter sites. See here for more information:
Will there ever be more services on the Freeview Light transmitters? | ukfree.tv - independent free digital TV advice
In some cases you might be able to receive from one of the transmitters that does broadcast these services. Obviously the lower down you are, the lower your chances.
Provide your post code or put it in the Digital UK website (tick the box to say that you're in the trade).
I did this for St. Bartholomew's Church (HX6 4DG) and it suggests that Ripponden is the only transmitter that can be picked up from. Looking at the contours, I'm not surprised. (HX6 4DG) Ian Fellows: Having located your post code, I ran it through the Digital UK predictor and it suggested that Emley Moor can be received from within it.
A post code covers a large area and that in a hilly area like Ripponden, what can and can't be received changes by property. The Digital UK predictor accepts house numbers/names to provide a more accurate result. I then entered your property's name which only returned Ripponden (no Emley Moor).
Bear in mind that the predictor is just that. For example, if you're willing to spend more on a larger aerial and taller mast then you might be able to achieve results (reception from Emley Moor) that you would otherwise not enjoy.
It might be worth looking around to see what neighbours have done. E

I have all standard freebies channels but since buying a new tv with Freeview HD built in we aren't getting any of the HD channels.
I've tried a few auto tunes and manual and it just doesn't seem to be picking them up at all.
The aerial is in the loft (town house so effectively the third floor) and the tv is a Samsung D7000.
Any help would be great, thanks.
