Freeview reception at PGSTAR T80
Terrain between PGSTART80 and Freeview masts
For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter.The diagrams below show the transmitters you can get a signal from - in order from best to worst. The blue line tests the line-of-sight between an aerial 10 metres above ground level (the line is red if there is an obstruction in the line-of-sight). You may be able to improve reception by raising the aerial higher - for safety's sake consult a reputable aerial installer if you need rooftop access. See below the diagrams for advanced options including selecting the receiver aerial height.
The terrain information (from Ordnance Survey and GIS) does not include forestation (where leaf cover changes with the seasons) or city buildings. The line-of-sight line can appear curved as this straight line moves over the Earth's surface.
When you click on a diagram, you will see map with the location selected shown with this symbol:

Hi
We have 2 freeview tvs upstairs that worked ok but now have really poor reception. One is was a brand new tv with a built in freeview receiver, the other an old tv with a freeview box. They now can't get BBC and the other channels are very iffy.
We are 10 miles from the Sandy transmitter, can you suggest what I oould do to resolve?

Hi, again back to 4G. Say BBC transmits on UHF ch 60 with a signal of 58 and the the LTE strength is 71. Obviously this is not enough to interfere with the transmitter signal, BUT, with other interfernce factors combined (ie atmospheric) could this be enough to cause 'an issue'?

ruth connelly: Has the change in reception coincided with work carried out on buildings on the industrial estate?
You may be only 10 miles from the transmitter, but there are certainly things that could be a source of difficulty.
See this terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
The red on the plot corresponds to Standford Bury where there is a row of trees which are potentially across the signal path. The industrial buildings could be a difficulty with those in bungalows being even lower to the ground and therefore, logic would suggest, potentially more likely to have difficulties.

Mariya : sorry for the delay, but I've only just seen your question.
I'm very very surprised you do not have Cbeebies, since its a PSB station (so you get it even if your signal is from a relay), and if your missing it, your going to be missing BBC3/4 as well. If you type your postcode (IG8?) into the reception predictor, you'll see what you should be getting. BBC signals are particularly strong, so I'd expect you to get something, and putting an IG8 postcode brought up no problems for signals from Crystal Palace.
Do you have a TV and a recorder? Check to see if its on one, and not the other, and perhaps see what transmitter they are both tuned into, and what other channels are missing.
The only other answer I can think of is that TV's and PVR's can be set up to remove certain channels from the EPG (the adult ones, for instance) - it could be that your TV has been set up in this way (probably by accident), and just needs to be reset.
As a stay-at-home dad I know that Cbeebies was a godsend when my kids were younger (CBBC does much the same thing now), so I know how valuable it is.

Clumsy:
It is rare to recover any electronics devices after fluids have been spilt inside them!
Asthere are mains voltage sections, I would strongly advise buying a new box and recycle the old damaged one.

Maybe offer it some garlic bread and a glass of chilled vino.

Clumsy: In future, when you have lasagne, have oven chips instead.
