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.

Yaz: Try unplugging just after C46 which is the highest channel from Bilsdale. Perhaps it may appear frozen but give it a while. Go away and make a cup of tea.
See which the TV is tuned to. View the signal strength screen whilst tuned to one service from each multiplex:
How do the strengths compare on the channels? When you do a manual tune on C43 but do not press the button to scan the channel, does it give an indication of strength and quality and if so, what is it? You will have to give it five or ten seconds to settle.
If you haven't had your aerial replaced from the days of four channel analogue then perhaps you could do with it doing. The analogue channels from Bilsdale were in the first third of the band of frequencies used for TV (Group A). PSB channels are in Group A but COM channels are in the middle third, Group B, so your aerial may be less sensitive to 'hearing' them (if it's a Group A one).
Bill Morrison: Evidently they are not tuned in then, or at least the HD services are not on their proper logical channel numbers.
Try and manual scan on UHF channel 54. If there is an option for mode with respect to the manual scan make sure it is set to DVB-T2 (high-definition signal type) rather than DVB-T (standard definition signal type).
A TV which is labelled as "HD Ready" does not have a DVB-T2 tuner in-built and will therefore require a separate receiver to show HD pictures off the air.
Hi thanks to Briantist and Dave Lindsay. One tv 6 year old ( probably only hd ready) the other 6months is only hd ready.
Will check 6 year old one as per Dave's answer. Thanks.
Hi I do not know but I presume I cannot get dab radio from Oldmeldrum. I do not own a dab radio yet and will only buy one when I know I will get reception!!
Bill Morrison: The six year old one would certainly only have a Freeview tuner. If you can tell us the make and model of the newer TV, then its easy to see if it has an HD tuner.
Although pretty much everything I've seen 37" plus for the past two years has an HD tuner as standard, there are some 32" and a fair number of 26" and below which still just have a Freeview tuner. And of course it could been an older model which you just happened to buy recently.
If you have a modern PVR, then that should have an HD turner in it, so you could get HD on that.
Hi Dave, thanks so much for your response. I have checked the TV which is tuned to Bilsdale with full signal strength and quality, but after the scan on the DVD free view+ box (unplugging after 46) I now get the message channel unavailable. Earlier the box tuning to PP was giving those sets (5usa itv3) channel TV guide but no signal.
Is there anything else I am missing? Of course I will look to investigate aerial upgrades but that will take me some time, and probably money I expect. It is frustrating as I had no problems a few days ago. Thanks in advance, I appreciate your help.
yaz: The fact that you are receiving the COM channels from Bilsdale on the TV tends to suggest that the aerial is not an issue, so I would of course suggest that it's not necessary.
I'm not sure what else to suggest. Perhaps one of the professionals will be along in bit with some suggestions.
Hi Dave, I have just got back from work and saw your post. I did a add new channelsscan just now and the missing channel set itv3, etc all appeared! Last night I was unplugging, scanning, etc till about 11pm to no avail. Thanks so much for your support. Would you advise investing in a masthead amplifier (think that's what it's called) as I am splitting the aerialsignal between the TV and DVD free view+ box?
