F Canfield: Hello tried the signal test. The signal strengh bar did show a faint glimmer (like 1%) of hope in one position but would still not give any reception. So more or less dead as previously explained. So tried tv upstairs with the old indoor aerial and what do you know The tv came to life. So proved my own theory something is blocking my previously good signal downstairs - if I only knew what is was!

F Canfield: I still cant help but feel that if you have verified that both these set top type aerials are working OK by having tried them on the upstairs TV, but both of them fail to give a picture when used on the set downstairs when located in approximately the same position as before when hitherto they did provide a workable signal, then there is likely to be some other factor involved which although maybe appearing as totally insignificant, isn't!
If the worst comes to the worst and you cant find a way around the problem, then should the breakfast bar be located on the rear of the house cant you install a aerial such as shown in the link? this mounted on a small wall bracket or even by using a gutter mount. (I refer to the DM18 as others are also shown)
By the way Mendip (@ 16mls / 128degrees) and Wenvoe ( @17mls / 291degrees) show exactly the same predictions as far as reception is concerned, that of being excellent, but not necessarily both being picked up at the same strength when using an indoor aerial, so you have to ensure that when you carry out an auto-tune your TV actually picks all the channels up from the same station.

This is the Mux channels used by both
Mendip: 61 - 54 - 58HD - 48 - 67 -52
Wenvoe: 41 - 44 - 47HD - 42 - 45 - 49

F Canfield: Sorry was not clear re upstairs test. The TV was the one from the kitchen. I took the kitchen tv and the old indoor aerial upstairs (I did not just try the indoor aerial in another set that was upstairs already) As you say looks like an external aerial is now the only option.
Thanks anyway. FC

F Canfield: Thanks for clarifying that point, and as regards to the aerial as you are obviously in quite a good spot for reception (excluding your kitchen!) then the aerial mounted in the loft should be perfectly OK, that is provided its not facing into a water tank or that you don't have any form of roof insulation installed containing any form of metallic element mixed with the fibres.
These are just the usual qualifications associated with loft aerials, and although the log aerial seen in the link I provided is an excellent aerial of the smaller variety, you have said in a much earlier posting that the TV worked OK on the one already in the loft so you only really require to run an extra cable from it, and its output preferably fed into a two way powered splitter to provide an aerial point in each room, as this would guarantee that both points get the same level of signal.

Gill: I would guess something has happened to the splitter. If it is powered, it could have blown a fuse. Please also see Freeview reception has changed? | ukfree.tv - independent free digital TV advice

I have a digital high gain aerial with 5 top and bottom elements.
My TV is a Panasonic TH-37PX70BA with a built in freeview tuner.
I also have a PVR, Panasonic DVD DMR-EX95 again with its own freeview tuner.
On both freeview tuners I can no longer receive the following channels: 8 Channel 4 , 11 PICK TV, 19 Dave, 20 Really, 29 E4+1, 46 Challenge, 49 Food Network
I have also had intermittent problems with:
12 Yesterday, 15 Film 4, 18 4Music, 21 VIVA, 24 ITV.
All were received in the past with no problems.
I have run the tests to exclude any Local analogue interference. I have also zeroid the TV and freewiew tuners before retuning them again.
I switched to Freeview fairly early so my aerial is pointed/lined up to the Mendip transmitter.
Since the Calne transmitter is now broadcasting digital, do you think I would receive the missing channels if I re-aligned my aerial to the Calne rather than Mendip transmitter?
If not, any other ideas how I can get the missing channels again.
