jon: On the subject of the variable gain masthead amplifier, is this made by Vision? however I am afraid I beg to differ from whats been said insomuch that the facts are, that if when the gain control on a variable aerial amplifier is slowly advanced and its noticed that this action is actually resulting in the signal level seen on the TV's check screen start to go down rather than up, then either the device is defective and is not working correctly, or alternatively its because the signal level being received by the TV is on the verges of being excessively high and is starting to saturate the tuner, as this is one of the main symptoms observed with this type of problem, no exceptions existing to either of these reasons mentioned as one has to apply.
Of course, and although its not so commonly experienced, but the actual aerial amplifier itself can also suffer from being overloaded, and with the symptoms seen being almost identical to the ones already mentioned on the TV because of the fact of being able to alter the internal operation of the amplifier.
The only reason for me mentioning this being the fact of you stating a 100% signal level being seen on one of the Samsung's, as that is too high as it does not allow an overload safety margin for a tuner, and as I have mentioned to others that the next step up from 100% is creeping instability, that is "if" when you stated 100% level that you are actually meaning the strength and not the quality?

RichardS: I fail to see what advantage a grouped aerial would have on the situation when the signal observed on one of the Samsungs is perfectly OK and indeed possibly excessive, this as well as the fact that the aerial might already be a grouped aerial anyway "if" it was installed for pre-switchover Freeview, as Hanningtons channels spanned 40 - 50 whereas now its 39 - 47.
The other point being, that a TV or box requires a certain level of signal to operate correctly with the minimum of glitches or any type being observed, but whether the level fed into the set comes directly from the active element on a so called higher gain aerial, or alternatively from a lower gain type that's been boosted, the TV will respond in exactly the same way as its the level that counts.
The reason I stated "so called high gain", is because that its only in near line-of-sight situations that this type of aerial might prove as an advantage, as if its used in a situation where near line-of-site is not the case then the directors on the aerial are liable to become restrictions to a signal that is deviating slightly in the angle received from its direct path, something which generally happens in situations where reflections from tree vegetation etc is applying.

I promised an update so here goes;
After a quick red herring whereby I found 6m of unbranded co-ax under the floorboards (which I cut down, giving a slight improvement, but not enough to receive the COM muxes) I got up my ladder.
Removing the old aerial I found a slightly corroded connection on the dipole. This alone may have been the problem, but having bought the new aerial I wasn't messing around trying to repair the old.
XB16B and Vision masthead amp fitted, I am happy to say that I have a great reception all round. Downstairs shows a signal of 80 and 0 errors. Upstairs is still 100 / 0, which I'll attenuate down.
Richard and JB, thanks for taking the time to try and help.

I live in Basingstoke RG21 3HQ. I have 2 aerials 1 tuned into London and 1 to Hannington.After the digital change over I got HD from Hannington. It has now changed back to London. Also I cannot get BBC2 from Hannington. In fact most of my channels are tuned to London, which seems strange considering Hannington is so near.What is causing this and why am I not getting 2 sets of signals tuned as I was before changeover.

Bob Sullivan,
London (presume Crystal Palace) transmits Freeview on channels 22, 23, 25, 26, 28 & 30. So on auto-tune, most (all?) receivers will allocate the standard programme numbers to these first - in preference to Hannington (channels 39, 41, 42, 44, 45, & 47) unless you do something clever during the tuning process. Many receivers will then allocate higher programme numbers (typically 800+) for the higher RF duplicates, even though the signal strength/quality may be better. It's worthwhile checking to see if this is what is happening in your case.
Are connecting your two aerials together to provide a single feed for your receiver? If so how?

Hi guys after some advice,, we used to point our aerial at crystal palace as before switch over we could get our best signal from there i live in gu15 2rg.
after switch over our signal didnt really get much better with constant breaking up and freezing so in my wisdom i brought a new aerail and fitted it in the loft pointing at hannington.
we now get 80% signal signal and 100% quility but we get constant pixalation and breaking up i have switched all routers ect off in the house to take these out of the loop.
i have tried and tried adjusting the aerial to see if it makes things any better to no avail.
it is far worse at sun going down time so i believe it is atmotherics but how can i get round this ????
i have tried pointing at guildford but cant get a signal from there with the aerial turned on its side.
any ideas as it really is driving me up the wall my pvr and the tv get the same problems.
you can watch the signal quility staying at full for 3 or 4 mins the all of a sudden dropping down to nothing then slowly going back up it like if you walked in front of the aerial lol.
any ideas?

Stuart: See the explanation of my experience with a loft aerial:
ukfree.tv - independent free digital TV advice
I believe that I have line of sight, or near line of sight, from the roof whereas you clearly don't.
A cause of poor quality at night could be caused by dampness forming on trees which the signal path passes through. Or of course, it could be damp forming on the roof which is affecting the signal quality.
I used Megalithia to plot the path from your location to Hannington:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
As you can see, in the direction of the transmitter the ground goes up about a mile away and you are therefore receiving from over the brow of a hill.
Click the link below that trace to see a map of the area, complete with a line joining you and the transmitter.
I zoomed out until the two points were on the screen. I then placed a ruler up to the screen and found the line to be able 21cm long. The distance to the transmitter is about 21 miles. This allowed me to work out where the brow of the hill is.
It is around Ferhill Road, near Hawley Park and around which there are trees...
The flat bit coloured red that you see on the plot is Hawley Hill which also has woodland on it.
I think that you need to have your aerial mounted outside, preferably above the roof level.

Stuart: I wrote the bit pointing you to my experience with a loft aerial before looking at the problem with the trees.
On the basis that you say that it is worse during darkness, I am of the opinion that it is far more likely to the trees. However, that doesn't stop you experimenting if it is possible to increase the gap between the inside of the roof and the back and front of the aerial.

thx for the reply dave, i would have put the aerial on the chimney if it wasnt for my complete fear of hieghts lol.
i see were your coming from with cove hills they would be in my line of sight i have a school field in front of me with the nearest tree about 250 meters away.
it just seems strange that 90% of the time i get great freeview on all muxs then every now and then it drops like a stone.
maybe its just something i am going to have to get used to, as cant afford a expert as out of work at the moment.
my pvr cant get on with it as when the signal drops it gets gaps in a recorded program.
we used to get the same problem on a 2 year old aerial mounted on the chimney facing crystal palace but it is a new aerial in the loft with new coaxail and new plugs i am using rf plugs for the join.
we could have got help under the help scheme but when the guy came out he said that the chimney had to many aerials on it so he could not do anything about it and went.
he said the bbc would not take old aerials down that have been up there since the seventies.
i had a new one fitted by a family member 2 years ago which didnt really work and i dont want to have to pay out again to rent a ridge ladder.
anyway thank you for your help.

stuart: It's not surprising that you couldn't pick up any digital TV from Hannington before switchover because it was severly reduced in strength in your direction due to the fact that Guildford used the same channels.
If you have a seventies aerial on Hannington, then you should definately try it now. Indeed, I see on Streetview that quite a few houses have an aerial on each transmitter.
If you have a Crystal Palace aerial and you haven't tried it since it switched to digital in April, then you should try that as well.
