Peter Cannon: I think the Freeview predictor is quite a bit optimistic, it showing green 'good' reception (now lower than 99% served) for your postcode. I will come on to the detail of why I say this, having done some analysis.
Suffice to say that the main difficulty you face is that the ground slopes upwards in the direction of the transmitter, or to put it the other way, there is a drop downwards across the last 300m or so. This tells us why you were advised that the aerial would need to be mounted on a tall pole. Whether it would work sufficiently lower down is another question, and I'm not saying categorically that it won't. Obviously, in the loft space it is even lower down still, than had it been outside, just above the roof line.
Google Maps and Bing Maps resolve the postcode to the same point, and I have been looking to confirm that this is indeed the location of Harper Walk. Being a new estate, the road name doesn't seem to be marked on any maps, hence I have been unable to be certain that the postcode is resolving to exactly the right place, and not somewhere else on the development. Google Maps shows an unnamed cul-de-sac off O'Donnel Road, backing on to properties on Clarkson Road. It is almost on a 90 bend, so I imagine this may be Harper Walk. For the following analysis, I have taken this to be the location of Harper Walk. Apologies if this is not the case.
How are your neighbours fairing? This is often a useful guide, although the situation may vary from house to house, owing to the slope.
My analysis follows.
The Craigkelly transmitter is 342 at 12.4 miles out, so you are fairly close, being that it is so high power. However, there are a couple of observations I have made:
In your immediate vicinity, in the direction of the transmitter, the ground rises up, on which there are houses, as can be seen by the contour lines on the OS Map:
Bing Maps - Directions, trip planning, traffic cameras & more
It looks to be that your ground level is around 115m to 120m. Where your line-of-sight intersects Ravenscroft Gardens the ground height is greater than 130m and less than 135m. It intersects Ravenscroft Street about where there is a cul-de-sac of Ravenscroft Street, this called Ravenscroft Street (it doesn't have its own name). At this junction there is a big tree. As well as trees there are buildings on the ground. So all in all there is an awful lot in your immediate vicinity to cause difficulty with reception.
The second observation I have made for reception at your location can be seen in the terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
At 3 miles out there is a peak of about 253m. The line-of-sight between you and the transmitter crosses the high ground of Holyrood Park, just to the east of Arthur's Seat.
Hovering the mousepointer over the terrain plot, it shows the height above sea level, and moving left and right the height changes accordingly. The highest is point is given as 252.2m at grid reference NT278726, and if you click the mouse at that point it will load an OS map with an arrow at this point. It points to the ground at Holyrood Park.
In light of all this, I went on Google Street View along Ravenscroft Street. Where aerials point tells a story, and that some of them are pointing to Angus likely means that they decided against Craigkelly reception because of difficulty with receiving from it. Thus, if *some* of those on the same path from the transmitter (as you) have decided against it, they being higher up, then the situation won't be any better lower down.

Peter Cannon: Having done all of the above analysis on the basis that the location is somewhere off O'Donnel Road, which is where the postcode resolves, I have now discovered that Harper Walk is in fact shown on the Google Map and was passed by the Google Street View car in May this year. Thus, you are further west than I had believed you to be.
That the postcode does not yet resolve to the exact correct location on the map, it could also potentially be the case that it does not do so on the Freeview predictor, and that the prediction is therefore that of another, perhaps nearby, location. Additionally, for the predictor to be anywhere near accurate it would need to be updated to reflect the fact that there are buildings (houses) in the area and that it is no longer open ground.
Be that as it may, I drew up another terrain plot, this time for the correct location:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
As you can see, Holyrood Park is still in the way. There is also a drop/slope downwards within a short distance, and this is an even greater gradient than at the location I had previously understood you to be at.

Steve Donaldson:
Well that's a very interesting analysis, well done.
A couple of minor points, I found Harper Walk on a google map without a problem, it's just to the SW of Harper Place.
This should show it Google Maps
A better grid reference would seem to be 290677 not that it seems to make any real difference to the LOS (not) path. (Despite the postcode that it turns up, clicking on Streetview goes to Harper Walk!).
When I looked quickly at another terrain plot it suggested there was clear LoS to the Craigkelly transmitter with aerial height of 10m. Ho hum!
But note, the predictions for Angus give a poor signal.
That all said, as I said previously, see how the neighbours are fairing as you have also mentioned. There is nothing like being there "on the ground" in the precise location with a proper professional signal strength meter. Often difficult to predict what sort of disruption a hill on the LoS at that distance would make in practice.
Frankly, I wouldn't bother with Angus, with the sort of disruptive weather conditions we get more frequently these days, I'd guess Angus would be too unreliable.
FreeSat would be the sensible option and if the TV already has a satellite tuner all that's needed would the Dish and LNB.

Ha, didn't see your updated post before I posted mine, too busy doing the analysis :)
I see we agree on the better NGR.

The next question is whether Angus can be used as a second choice, and I think the answer is, unfortunately, "no".
The terrain plot looks good. Barring nearby houses there may be line-of-sight at 46 miles on a bearing of 7:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
However, the predictor does suggest good reception may be possible of the three COM multiplexes, but nothing on three PSBs.
The Penicuik relay transmitter at 6 miles out on a bearing of 203 is co-channel with the PSBs of Angus, albeit that it is vertically polarised and Angus is horizontally polarised.
Further, the Google Street View car has been along Torrance Row once, in July 2022. This shows three houses with a TV aerial and a Triax satellite dish. These aerials all point to the Penicuik relay. Moving round onto Pincott Drive it is possible to see the backs of houses on Torrance Way. Three of them have a TV aerial and they are all vertically polarised and pointing at Penicuik.
There are a few houses on Bain Rigg with a Craigkelly aerial and a Triax satellite dish mounted on the same pole, so it looks like it may be the same installer.
The Penicuik relay carries only PSB channels, and therefore does not offer the full complement of Freeview channels. It might be worth enquiring with those properties that have a TV aerial to see if they can offer any more guidance.
I stress, even if you can receive from the Penicuik relay, it will give you only the PSB channels, which are BBC A (PSB1), D3&4 (PSB2) and BBC B (PSB3):

Peter Cannon: No. You can't use a terrestrial (Freeview) receiver for receiving the signal from a satellite.
As you already have a dish then you could have Freesat. The list of channels available are here:
Channels List and On-Demand Players | Freesat
Some TVs have a built-in Freesat (satellite) tuner, in addition to the Freeview (terrestrial) one. As you already have a dish then this may be the best way for you to access to more channels.

Peter Cannon: SkyQ use two wideband LNB connections, one for horizontally polarised transponders and one for vertically polarised transponders.
Those connections are incompatible with most, if not all, TV satellite connections, which require connection to a Universal LNB.
Universal LNBs work by switching between H/V according to the voltage 19/13 volts and between low-band 10700-11700 MHz and high-band 11700-12750 MHz, depending on whether a 22 kHz tone is present
Unless you can access the dish yourself to change the LNB to a Universal, your best option is one of the latest Freesat boxes as these are compatible.

Peter Cannon:
Ah, I don't know if StevensOnln1 can help? But if that's a standard Sky Q LNB on that dish, AIUI, it will have only two outputs and will only work connected to a SkyQ box, so you will have to change the LNB.
I assume that if you no longer subscribe to Sky, you had to return the Sky Q box.
There are some "hybrid" LNB's around that have about 8 outputs 2 of which are Sky Q, 2 Sky HD and 4 standard. I don't know anything about them, but I'd guess Sky would not have fitted them and in any event appear to need a Sky Q box to power them.
Maybe someone more knowledgeable on this (StevensOnln1?) may be able to help on that point.

Chris.SE & Peter Cannon: The 3rd generation Freesat 4K boxes are compatible with the Sky Q wideband LNBs, but as already stated you would need to replace with a Universal LNB to connect most other receivers.
