Freeview reception at PGSTAR T60
For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.
You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.
You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.
These icons show the potential locations for 5G-at-700MHz services that may interfere with Freeview reception. For actual mobile device reception prediction (at 800-960MHz and 1710-2170MHz) see these phone operator's mapping sites: Three O2 EE VM

John Curtis: I suggest that the two most likely reason for getting no signal from the rooftop aerial is because either the lead is not connected all the way through and/or because there is an amplifier connected inline which is not powered on.
The amplifier could be on the mast, in which case it requires a separate power supply that connects inline, often behind the television. Or there could be a distribution amplifier perhaps situated in the loft which feeds signals to more than one room.
Judging by the size of the aerials on the rooves of the houses in your area I think it highly unlikely that the signal lower down and indoors is likely to be sufficient for an indoor aerial!
Whilst you are only 31 miles away, you do not have anywhere near line-of-sight. The difficulty is the higher ground on which Camberley sits, which is in the way.
If your aerial points to Crystal Palace, which is roughly east north east, then see if any of your receivers have manual tuning on. Try manually tuning its broadcast (UHF) channels which are 23, 26, 25, 22 and 28.

Steve Cheshire: No. The Licence Fee does not guarantee availability of reception.
From what I can see, your postcode resolves to a block of flats. This makes me think that this aerial you refer to, which is on the roof, is a communal one. If so some then communal aerial systems require adjustment to take account of the new channels.
If, one month on, no resident has bothered to notify the landlord then it isn't likely to get fixed!

I have inbuilt Freeview on my LG32LG5700 TV. I am unable to select another mast/receiver option on this model. Since the last digital update my signal has been poor on ITV channels and BBC even poorer to non-existant on other channels. I hasten to add this is the case with any TV tried in the house. The signal being picked up from my home in Cheshire is now broadcasting in Welsh (received from Wales,10plus miles away), and not from Winter Hill. Without the cost of a new TV aerial (which I believe is a digital one), what are my options please?

Jeff Sutcliffe: There is no such thing as a "digital" aerial. An aerial isn't bothered about whether a signal is analogue or digital, but only dependent on frequency of the signal.
The purpose of the automatic tuning scan is to look through all frequencies to 'see' what signals are available. Once completed the receiver must 'decide' which to use as its main ones (the rest being put in the 800s). In this case it has chosen to use the signals from the Moel-y-Parc transmitter in Wales. This in no way indicates that the aerial is not picking up Winter Hill. The poor reception comes about because the signal being received is from a direction other than which the aerial faces.
I downloaded the user manual for your TV here:
LG 32LG5700 Support: Find Manuals & Warranty Info | LG UK
Page 45 of the booklet (page 47 of the PDF) says that you have manual tuning at your disposal.
Run the automatic tuning through without the aerial plugged in. Then manually scan UHF channels 50, 59, 58, 49 and 55, these being the five standard definition channels of Winter Hill.

Many thanks Dave, read one of your posts and done that now already, the BBC still squeaks on an off-it never used to! I have a bigger problem resorting and organising my Median TV channels as manually tuned to your suggested channels but BBC is still also programmed to receive Welsh as channels 001/002 with BBC North in 800's. Not sure why for my postcode in Cheshire the strongest transmitter is suggested by this website as Moel-y-parc? I hope I am not expected to do a manual retune for an update every time.

Jeff Sutcliffe: Signals spread out according to the terrain; they aren't delivered by a postal service!
You probably have clear line-of-sight to Moel-y-Parc, or are not far off, but you certainly don't to Winter Hill. See this terrain plot to Winter Hill:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
The higher ground on which Halton and the surrounding area sits is in the way. You are very low down and the motorway and trees appear to be in the signal path.
The signal strength screens should allow you to identify which transmitter you are receiving from:
Moel-y-Parc 45, 39, 51, 52, 48.
These numbers relate to BBC One, ITV, ITV3, Pick TV, Film4, respectively (as do those given in my previous posting for Winter Hill).
Thus, if the BBC One you are watching is tuned to C45 then it is being received from Moel-y-Parc. Any poor reception is likely because the aerial is pointing the wrong way for the signal being received.
For those sets without manual tuning you may be able to avoid picking up Moel-y-Parc by having the aerial lead unplugged during its part of the scan; say the first 50%.

Jeff Sutcliffe: If you have a Sky box or another device which puts out an analogue signal onto the aerial system then ensure that it isn't on or near the new Winter Hill channels 49 and 50.

Thanks for the advice Dave I will take a look or boost my already boosted aerial I guess. I have no Sky or similar. I'm sorry I thought the transmitter signal strengths had been adjusted recently, I thought it may have been a transmitter issue.

Jeff Sutcliffe: Once you have each set tuned to Winter Hill (having verified the channel numbers shown on the signal strength screens) then don't be tempted to retune. Your sets will give the best picture and retuning won't improve it.
With digital there is strength and quality. Quality is effectively the digits that make up the picture being intact. Strength is the level of the signal.
Amplification makes a signal bigger but cannot improve its quality. See:
