Prior to the recent freeview channel changes I had every channel and a strong signal. Every channel was approx. 90% and the BBC channels at 100%. But it took me more than fifteen attempted channel rescans to get most of my channels back (not all) but now with poor signals and blocking / pixelated pictures on most channels. For one example Film four is now unwatchable.

What has changed?

Hi,you could check reception with a second hand fv box or overhaul yr aerial system,try a set top aerial and see what local reception condiions are like,sometimes the tuners go faulty after a number of years.Myself,i'm lucky,i live in a swamp area.

Hi,there is another way to improve reception but it is only open to those who can use a soldering iron and are capable of doing work on aerials.n............

Drek Springall: Check the DigitalUK and terrain links - Crystal Palace and Sandy Heath are almost on the same bearing as your original transmitter, but would come up first in any scan - so its likely thats what the tuner has found first. Check, and if thats the case, manually retune.

Hi,one way of improving yr reception is to remove the aluminum dipole which has the coax cable attached to
it and replace it with an insulated thick copper wire,bent to the shape of the dipole,yr aerial should pick better,copper is very good for aerials,as a instance,north of oxford,on a set top aerial, i can get a locked
picture from hannington,abt 40 miles south,before it was 5percent on the signal strength.This is done at yr
risk,NO legal responseibilty of any kind accepted.You might find the signals too strong,worth a try if you're up to it,don't do anything you can't cope with.

This is not generally a good idea. The replacement dipole element needs to be exactly the same domensions and shape as the removed aluminium one, mounted at exactly the same position as the old one and in the same orientation of course. Further, copper develops green verdigree on exposure to the atmosphere and that is a very poor conductor. Plus there could well be electrolytic reactions between the copper and the terminals unless they are all plated to prevent both corrosion and electrolysis.

The best way of improving reception is to use the correct aerial, mounted correctly outdoors, aimed accurately at the transmitter and properly connected using good quality cables.

MikeP: This is the basic construction,you would need to protect the the wire,etc,theres corrison between the copper coax and the connections,in all aerials after a while,i have had an aerial last over 8yrs,the wire needs to be the shape of the folded dipole but so long it looks like it,it works,sorry all aerial fittings are subject to corrsion but the advice is for people who can handle same but where theres a problem of marginal signal pick up its worth trying it,i have an set top here cause the field strength is high enough not to need an aerial.The information is for people who are able to do the work,n............

Sorry,as i said,if the pick up is still proving to be difficult,its a good solution,if preamps will be affected by the mobile phone system prove to be cointerproductive.If i can get a locked picture from Hannington at 40 or so miles on a indoor set top aerial then it works,all the others gave me 5percent on the box,n.............

Replacing the dipole is not a general solution . It just happened in your case that using an insulated dipole shifted the frequency response to improve the wanted channel. Sheer luck! Usually any modification of an aerial will not improve reception.

Colchester should see a strong signal from Sudbury with the correct aerial . AS Mike says because its easy for the tuner to pick up the wrong transmitters on similar frequencies (in that area) my guess is that a manual tune is necessary . Use the listed UHF channel numbers listed on the Sudbury freeview page to do this. (note that the "channels" referred to in tuning are UHF channels not the freeview channels)
Some tvs will need the tuning first to be cleared by doing an auto tune with the aerial disconnected.
side note .. the ideal aerial is a type E . I wouldn't yet buy a new aerial because next year Sudbury will get best reception on a type K ! Though in a strong signal area like Colchester if you have a wideband aerial it should work now and next year too after the major frequency change.

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.
