The symbol shows the location of the Angus (Dundee City, Scotland) transmitter which serves 130,000 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.

Is the transmitter output the same in all directions?

Duncan Killin: Yes, but on lower power than the other channels and out-of-group as far as C/D aerials go.
Powers are PSBs @ 20kW; COM4-6 @ 10kW; COM7 @ 3.3kW.
Previously all channels from Angus were in Group C/D (top third of the band of frequencies) and consequently Group C/D aerials will have often been fitted. A C/D aerial is most sensitive on C/D channels and less so lower down the band which is where COM7 (BBC Four HD, BBC News HD etc) is.
Try using the manual tuning function. Go to it and select/enter UHF channel 31 (554MHz) but don't press the button to scan/add services immediately. Rather, wait and see what readings of strength and quality you get and whether they are stable or variable, maybe having viewed it for a minute or two. By not pressing the button to scan/add services you have a signal meter whereas by pressing it it will simply determine whether it's good enough or not.

I live in Blackness Road Dundee and my tv signal has not been working all day, neither are my neighbours. Can you help? 27th May 2015

Linda Mann: No engineering work is indicated by Digital UK as taking place at the Angus transmitter.
If you reside in a block with a shared aerial system and the neighbours you refer to also use this system then the problem could be a fault with the system. Therefore you will need to notify the party responsible for it.

I have tried your tip -->> ##Try using the manual tuning function. Go to it and select/enter UHF channel 31 (554MHz) but don't press the button to scan/add services immediately.

and there is No signal, but as I read that there is work going on and a ''weak signal ' I'll have to accept that channel 24 , for example, is unavailable . The shame is that there appears to be No info as to when the work will finish, why can't they indicate any date to an end to their work ?

Bob: The posting you are referring to made by Dave Lindsay on April 20th, was in reply to an enquiry from a viewer wanting to know whether (or not) the Angus COM7 (HD) transmitter was in full time operation as yet, the transmitter in question broadcasting on C31.
If by 24 you are meaning EPG 24 / ITV4? as C24 does not exist on this station, then ITV4 is broadcast by the Angus transmitter on COM6 / C49.
By the way, any enquiry involved with a reception problem has to be accompanied by a post code, as its impossible to make an assessment on your reception possibilities without this information being known.

Forfar
The postcode is dd8 2sj ..... and yes I should have said what you replied -->##ITV4 is broadcast by the Angus transmitter on COM6 / C49.##
.....ITV4 on COM6/C49 and the others listed above at COM6/C49. The rest of what I posted still stands with corrections ##and there is No signal, but as I read that there is work going on and a ''weak signal ' I'll have to accept that C49 /ITV4 and others , for example, are unavailable just now . The shame is that there appears to be No info as to when the work will finish, why can't they indicate any date to an end to their work ?##
Possible I should have linked to another message this one -->Tuesday, 16 June 2015

Bob: On the subject of time factors involved with planned engineering works, these are never mentioned simply because of the nature of the work, as things aren't always as cut and dried as it might seem when dealing with RF equipment, as unforeseen snags can, and do, crop up.
The time factor involved being even less certain if said work involves anything connected with the mast, as the progress of the work is totally dependant on weather conditions etc.
However, on the subject of no signal on C49, although the signal path terrain indicator shows that the signal from the Angus transmitter (@ 11 miles / 236 degrees) is not quite line-of-sight to your location by being obstructed from around 1.5 miles prior to it, obstructions to a signal always having a greater effect when they occur close to the receiver, and with this possibly being the reason why you are not receiving any signal on C49, especially as COM channels are transmitted on half the power of the PSB channels, i.e: PSB 20Kw / COM's 10Kw.
Purely for a test, if your TV or box offers "manual" tuning, enter the facility and enter C49 into the box, but do"not" press search or scan but wait to see if anything is indicated in the strength / quality bars, as this procedure results in the tuner acting in the form of signal meter free of lower threshold for reception restrictions, likewise if anything is being received, it will be indicated no matter how low it might be.

Hi jb38
9:56 AM , again, I've done as you asked using the manual scan function in the ''set top box'' as a signal meter , but not scanning.
The signal strength varied between 28% most of the time and up to 40%, the quality was zero , with a very few odd moments when a pixilated picture showed only to freeze, and the [No or bad signal ] message appeared. So it looks like we'll just have to be patient until the work ends .
Re your info quote -> ##the Angus transmitter (@ 11 miles / 236 degrees) is not quite line-of-sight to your location by being obstructed from around 1.5 miles prior to it, obstructions to a signal always having a greater effect when they occur close to the receiver, ##
Dunnichen Hill is sort of south-south west of us, so that is probably the ''Obstruction''
Maybe later on we'll get a taller pole put up on the chimney stack to carry the aerial..
........so thanks for all the info and maybe when they switch back on after their work we'll go back to watching the Tour De France on ITV4 even if it is pixilated some of the time ..

Bob: Thanks for the update, your detailed findings on the outcome of the test having confirmed my suspicion as to the most likely reason for your problem, but which as you have referred to, might improve somewhat once the engineering work is completed.
One little point though, as far as possibly mounting the aerial on a taller pole is concerned, the general rule of "the higher the better" does not necessarily apply in every case, (transmission aerials excepted) as in situations where reception is non line-of-sight with the transmitter, its frequently found that a much better signal can be achieved with the aerial being mounted lower down at around gutter level, and with the aerial being tried to the left and right of the lower mounting position.
I only mention this just in case you, yourself would be installing a larger pole, if you are? leave the TV on the manual tune signal test screen whilst you adjust the aerial.

Yes I might well adjust the aerial myself , ..............but eeerrr ummmh ahhh, how does one comminicate with ones beloved who is indoors watching said ''signal test screen '' as to when the aerial is in the best position, so that one can tighten the bolts holding said aerial , there was a TV show where contestants shouted Up a Bit , down a bit, left a bit .......Fire , having ones beloved shout instructions ''oot ra windae'' when one is up a ladder , may not be the ideal solution !!
