gerry: Have you tried manually tuning?
PSB2 mux carries UTV, C4, C5 etc and is on UHF channel 59.
COM4 mux carries ITV3, QVC etc and is on UHF channel 54.
COM5 mux carries Pick TV, Dave, Really etc and is on UHF channel 58.
Try going to the manual tune function and selecting/entering the relevant UHF channel number but don't press the button to scan/search. A lot of receivers give an indication as to signal strength (and maybe quality) at this point.
If it shows a signal is present, press the button to scan/search the channel.

Sean: Yes, do a rescan now; all Brougher Mountain channels (should be) on air.
Brougher Mountain transmits a special multiplex which carries RT 1 and 2 and TG4. They are in standard definition but a high definition (Freeview HD) will be required to receive them. As you have Saorview, the Brougher Mountain mux may not be required.

Sean: It is Freeview channels that I was referring to in my first short paragraph. All are now on air.

william: Reception of RT from Black Mountain (which is adjacent to Divis) requires a Freeview HD receiver. This is because the signal uses the DVB-T2 specification which is that used by Freeview HD broadcasts, although these channels are in standard definition only.

mavis: I gather you are receiving from Dover transmitter as it broadcasts Sky News on C59.
C59 is the highest channel used by Dover and is therefore picked up last when the TV carries out its scan. What is probably happening is that your TV is storing signals from other transmitters before it gets to Dover (which uses the higher channels) and that these other signals are filling the memory and leaving it without memory to remember C59.
Dover's lowest channel is 48 and the automatic tuning scan runs channels 21 to 69, so have the aerial lead unplugged for the first 50% so as to avoid finding some signals that are lower down (and occupying the memory).
If it gives UHF channels as it scans, plug in about C45.

Colin Gilliland: When you manually scan on C39, ensure that DVB-T2 mode is selected rather than DVB-T.

matt: Never.
The Digital UK Postcode Checker suggests that you might be able to receive the full service from Limavady. Obviously this does not take into account any local obstructions which may preclude reception.

John Breeds: I will make one observation which you could perhaps be unaware of and that is that the new Bexhill relay transmitter is co-channel with Bluebell Hill's PSBs.
TN37 is obviously a large area and how likely it might be a problem will vary across the area.
The Bexhill transmitter is horizontally polarised, like Bluebell Hill. It is on the roof of the Hastings Direct building.

JK: The main Freeview channels come from Divis whereas the NIMM is from the adjacent Black Mountain. At your location they are only 2 degrees apart which is probably nothing as far as sensitivity of the aerial is concerned.
However, it is always possible that there is something that is reducing the level of the signal from Black Hill. For example, a building or tree.
With this in mind, try moving your aerial around the loft and see if reception of the NIMM improves. I suggest that you connect your TV directly to the aerial (perhaps via the variable booster but not via the Loftbox). This will rule out the possibility of the Loftbox causing the issue.

Drew Hunter: The Newtownards transmitter does not broadcast those channels. Knowledge of your postcode or nearby postcode such as a shop would allow a prediction of whether you might receive these services from one of the transmitters that do carry them.
