Jonathan: If you've got sufficient spare cable in the loft to trim and remake conections if needed, then just put some coax connectors on instead of F type. If there isnt't enough, you can get F-Coax convertors which should be a lot cheaper than more attenuators.
Also, see it you can check your old cable for continuity and shorts.

Jonathan - I assume you have an aerial socket plate on the wall. If so I have found some of these cheap plates give very poor connection when installing them around my house. In one case I gave up and fitted a F plug face plate & made an F plug to standard aerial plug fly lead up which works extremely well.

I think these days best practice is not to have socket plates at all; just to bring the coax through the wall direct into the set.

...start to watch the channels rise in the progress bar, then as soon as they get to Mux Ch50 re-connect the aerial and that will exclude anything other than Oxford from loading".
UHF channel 50 is used by Hannington and Sutton COldfield. If you want to store just Oxford, try to reconnect the aerial when the scan is after 50 but before 53. This can be tricky, particularly if the TV dosen't show UHF channel numbers.

Hello,
Since switchover, I have had no EPG, but can recieve all 5 muxes. I tried rescanning, but this has not helped. The EPG is still blank, so I'm having to set timer recordings manually, which is time consuming, as I have to scroll to the start and end times in one minute increments!

Nicholas - I recall that some boxes use an EPG source that has stopped.
If you post here - or google - your box/TV Model you may see something.

I have an icecrypt T5000. On one particular aerial socket, it is only picking up the BBC mux (connected elsewhere in the house it is fine as are the other freeview boxes/TVs in the house)
There are two other aerial sockets in the house and all three are run off a 4 way non-amplified splitter
My postcode is NN13 5PN and the (loft) aerial points to the Oxford transmitter.
I have done the reset advice etc and this freeview box is only connecting to an analogue TV with no other devices connected
Is an amplified (powered) splitter likely to fix this problem or could it be something else ?
Thanks in anticipation

Alex - what happens when you use one of the other boxes on the particular aerial socket?
Can you get at the splitter? Try switching the connections and see if the problem moves, or is linked to the down wire.
Remove socket and check for dead beetles etc.

Hi yes it sounds like this one socket isnt getting enough signal, this could be due to a wiring problem, i.e. poor quality cable or poorly made connections at the end of the cables (the brading should never be touching the centre core!), or simply that splitting the cabel that many ways is killing the signal too much. Try checking your connections first, if that still fails, use a masthead amp such as this (http://tradeworks.tv/acatalog/Vision_4_Way_Variable_10-20dB.html), this can be powered remotely - ideal for lofts with no plugs, or a simple TV amplifier such as this (http://tradeworks.tv/acatalog/Triax_4_Way_TV_Amplifier.html).
