The symbol shows the location of the Darwen (Blackburn with Darwen, England) transmitter which serves 15,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Darwen (Blackburn with Darwen, England) mast?

paul marsh: I think that it's not very likely that you will be able to receive from Winter Hill even though it is only 5.5 miles away.

Have a look around and see if anyone has a horizontally polarised aerial on Winter Hill. This (if there are any) might be a clue as to whether it might be possible. If there aren't any, then it might be because no one else has tried or it might be because it isn't possible.

Other than that, Freesat is probably your best option for additional free-to-air channels. There are some differences in the offerings of Freesat and full Freeview (ITV3 IS on Freesat):

My internal freeview HD tuner in my TV has lost all signal, yet my two set top boxes (not HD) are fine. I got a signal back on the HD tuner for a few hours the other day but it soon disappeared again. The aerial is on the roof.

shaun: As the Mendip transmitter is located at just under 5 miles away from you then your problem "might" be caused by an excessively high level of signal being received, this always affecting HD before SD and with in many instances the latter showing no signs of any problems.

Should you have any type of booster fitted then for a test either remove or bypass it.

Thanks for your answer but isn't the mendip transmitter in the southwest? I'm near the winter hill transmitter group in north west England. There is some work going on at the moment at the Darwen transmitter (part of the winter hill group) but would that explain my HD TV receiver not picking up any channels (not just the HD ones) whilst my other set top boxes are fine. I tried removing the booster I have but then none of the receivers worked! Bizarre.

shaun: Yes, sorry about that as I had meant to say Winter Hill, everything else said still applies though.

I also realise that work is going on at the Darwen transmitter located @ 4 miles away, but this station is not indicated on the reception predictor as coming into the equation as far as reception at your particular location is concerned hence the reason why I did not mention it.

I live in Darwen ( BB3 2QA) and feel short-changed with my freeview reception - do you know if there are any plans for Darwen residents to be able to receive the full compliment of freeview channels.

Alan Smith: No, there are never likely to be more channels broadcast from Darwen transmitter, and over 1,000 other Public Service-only transmitting stations. See here for an explanation:

Londonderry (Northern Ireland) Freeview Light transmitter | ukfree.tv - 11 years of independent, free digital TV advice

Judging by the Digital UK predictor you are not in a position to receive directly from Winter Hill, and therefore pick up the full complement of channels.

Recently Film4 became available from Public Service (PSB) relays, but this was because capacity became available on an existing multiplex, so there isn't likely to be any more new services.

The only advice I can offer is to look at free-to-air satellite such as Freesat.

Hi, I have recently installed a 52 Element Wideband Aerial to hopefully receive broadcasts from Winter Hill as opposed to the Darwen transmitter due to a muh more comprehensive channel line-up.

I receive some channels now from Winter Hill, but not the rest? I am receiving Al Jazeera English HD, which isnt really of any use to me, was hoping to receive the channels on the same lineup as Dave.

Any suggestions anyone?

Thankyou in advance.

Anthony Grime: Try manually scanning each UHF channel - it is worth looking at the different equipment you have to see which is most useful here. Some have no manual tuning at all and some do but give little information.

If you enter/select the channel but do not press the button to scan/add services and instead wait and see if it gives you an indication as to strength/quality, as in doing so receivers operate as basic signal meters, something which wouldn't be the case having scanned.

See the full list of Freeview services:


Digital UK Industry - Channel listings


There are six main multiplexes plus the new quasi-national COM7 HD mux that you are receiving (as you have Al Jazeera HD). Each is a single signal, so focus on one service from each. For example, for PSB1 look at BBC One, all other BBC standard definition services are also on PSB1 so there is no need to look at them:

PSB1 - BBC One - C50
PSB2 - ITV - C59
PSB3 - BBC One HD - C54
COM4 - (10)ITV3 - C58
COM5 - (11)Pick - C49
COM6 - (18)4Music - C55
COM7 - (107) BBC News HD - C31

Ensure that you aren't tuned to the Darwen relay (for PSB channels) on 45, 39 and 42 respectively. This information is usually given on the signal strength screen.

Anthony Grime: I help out on here as a technical bod rather than an aerial installer.

The higher the gain of the aerial the narrower its acceptance angle. That is, gain in one direction is gained by increasing "loss" in others.

As you live at the bottom of a drop you don't have any "beam" from the transmitter to which direct your aerial. For that reason a high gain aerial is not recommended.

A lower gain aerial will offer a wider acceptance angle over which to receive. With digital quality is important, and more so than strength. Strength can be increased with an amplifier whereas quality is down to the aerial. That is, a poor quality signal can't be improved with an amplifier whereas a low strength one can be increased in strength. A low strength poor quality signal with an amplifier will give a higher strength poor quality signal which is therefore of no use:

Television Aerial Boosters / Amplifiers, Splitters, Diplexers & Triplexers

There are no guarantees in your situation, but a log periodic aerial, probably in conjunction with an amplifier, would seem to be the most suited. A DM Log from Aerials and TV Sheffield is one example:

Aerials, TV Aerial and Digital Aerial

This is in fact a Blake DML26WB. Blake do a DML26T which is wideband expect for the top channels, C61 to C69, which are now in the hands of the 4G operators. Either will work, by with the WB you could, potentially, have to fit a filter to block 4G if it proves to be an issue.

The other thing I'm wondering - as I say I'm not an installer - is whether, because you are at the bottom of a steep drop, tilting the aerial upwards slightly might not be a bad idea. The Blake DML26 has a clamp which allows it to be tilted.
