Hi Dave,
Both TVs are running of a splitter now and recieving good-very good signal. I managed to get both boxes record the same programme to check that having both on wasnt causing problems. That checked out ok but after an hour of watching and recording my box suddenly stated no signal when trying a channel, but signal details hadnt changed.
I reset the box completely and rescanned several times before getting everything back.
Watching seems ok but when recording anything I get constant skipping again, it seems to be bbc one mainly, Is it worth trying an attenuator for my box, would you suggest a variable one or a specific db
Its great that you are helping

nicola: I would get a variable attenuator, such as that which is shown on the other page entitled "Freeview signals: too much of a good thing...". These usually give you a range up to 20dB.
Put variable attenuator into eBay and some will come up.
I would try putting it on the feed into one of the boxes. If 60 or 70% strength gives 100% quality, then I would try it at that.
If it works, then you might try putting the attenuator before the splitter and adjusting so that both devices work.

nicola: Watch out because some of the attenuators have F-connectors (which are the threaded and therefore need screwing together) and some have the coax connectors on (the sort you just plug in as found on the back of TVs and recorders).
The most commonly encountered type of connector used for terrestrial aerials are the plug in coax ones, so you probably want one of these. For example:

Hi Dave here is an update, I have been running both boxes on the splitter and have come across a few things, Both boxes get a blank screen when going onto really, and itv2+1 Prob others too. both boxes are skipping when recording.
my box states signal quality good, signal level around 70% so I am worried that I need to boost this rather than use an attenuater to dampen.

nicola: Be aware that the three commercial (COM) multiplexes are currently on much lower power from Oxford than its Public Service Broadcaster (PSB) ones.
Thus, you will have to ensure that you attenuate enough to make the PSBs watchable without attenuating the COMs too much so as to make them too weak for your machine to show a picture.
On 18th April the COMs will go to their full final power, which will be lower than that of the PSBs (which are already at their full final power). So it is to be expected that there is a difference in signal strength.
The scale on different boxes will differ, so ultimately it is try it and see. As an example, my Sony recorder (HXD-RDR870) gave strengths of around 50 to 60% before switchover and it worked fine. The quality was 100% and therefore the picture wasn't degraded.
If the 70% is on BBC or ITV1/C4 and ITV2+1, Really is breaking up or gone, then you need to reduce your attenuation to let some more of the signals through.
For a full list of Freeview services and what multiplex they are carried on, see here:
DTG :: DTT Services by Multiplex
Basically, I would look at the first service in each multiplex. So check BBC One, ITV1, BBC One HD (if applicable), ITV3, Pick TV and Yesterday. As I say, the trick will be not to attenuate too much so as to loose the last three, but enough to reduce the level of the first three enough.
Come 18th April this will be easier because the COMs won't be so weak with respect to the PSBs.

Hello again,
I just checked the channels that you suggested and I dont get ITV3 and PickTV at all despite them showing up on the program guide.This is without a booster or attenuator connected, would an antenuator not make this worse rather than better and would a variable booster be better until the signal strength of the transmitter is at full power again.

Nicola - where you are located you should not have any problems receiving any of the channels, even with the power restrictions on the commercial multiplexes. You should easily be able to passively split the signal to 2 receivers. Either there is too much signal (likely if you have a roof mounted aerial) or you have fault (Bad connection, short circuit in the aerial cable etc). My advice would be to have it checked by a profeesional aerial rigger.

nicola: It is a possibility that the reason your receiver isn't picking up two of the (weaker) COMs is because the strong PSBs is desensitising your receiver.
That is, it is less sensitive to the weaker COMs because it is reacting to the strong PSBs.
Change to ITV3 and bring up the signal strength meter. Now connect the attenuator into the aerial lead and turn it and see what happens. Get an idea of where the strength is at its highest. See if adding attenuation actually increases it.

I keep loosing my freeview signal - sometimes ok for days, sometimes drops for 10 minutes then ok, then sometimes drops for 24 hours+. my aerial (newish one that was sold for digital use) is halfway up my roof outside pointing towards Oxford. Signal is great when its on, then it just drops. It doesn't scatter, just goes to no signal. Has gone off and on about 10 times today, 20-30 minutes at a time. Anyone have the same problem?

LJ: As Oxford transmits on vastly different power levels between the BBC/ITV and the three commercial multiplexes what channels are you saying that you lose?
