ATV Digital Coverage Map
This is our Sheffield Area Digital Coverage Map. It was originally Sean`s idea so he deserves the credit because he kept pestering me to do it ! Unlike the "Post Code Check", this is accurate as it is a record of (most of) the aerial installs we have done and if Digital actually worked at that site. It also shows which transmitter the site is on, which helps us supply
the correct aerial to customers purchasing one from us.
It should be stressed that (occasionally) we have found places where two houses side by side can get markedly different qualities of reception, this is particularly common if tree`s or high buildings are close to the reception path.

ATV Topography of Sheffield Area Map
(Including the importance of “Line Of Sight”)
We had the map below specially created for us at great expense. The lowest ground is purple and then we go through blue, green, yellow and various shades of orange to reach the highest altitude, in addition spot heights are indicated at various points. The map is useful in helping us supply the correct aerials to customers from areas with which we are not familiar.
As has been stated on a few pages of this site, in the UHF game "Line Of Sight" is (almost) everything, i.e. which direction does the antenna have the clearest run at / best view of the transmitter ? It is for this reason that aerial installers are amongst the most knowledgeable about where all the hills are in any particular area. They also tend to know where all the tall buildings are, and the large trees for that matter !
Our shops location provides a good example of the map indicating potential transmitter (TX) choice and the importance of line of sight. Crosspool is only about two miles SSW of us yet our pictures from there are poor. Emley Moor is 17 miles North West from here yet we get (more or less) perfect pictures. Finally Belmont is no less than 55 miles away (due East)
yet our pictures are better than off Crosspool. Examination of the map provides some clues. Just behind us (SSW) is the high ground of Walkley Bank and this is identifiable on the map. We are situated at the bottom of the Don valley and as shown on the map this runs (up stream) NNW from here. Thus we get a pretty clear path onto Emley. Finally in the
down stream direction the Don valley is East, this explains Belmonts superior pictures over Crosspool despite the huge disparity in distances to the transmitter(s). The relatively high number of people in Sheffield who are on Belmont is one of the best examples of the importance of Line Of Sight. Belmont is 50 to 60 miles away (and there are 4 or 5 other transmitters closer than this, not counting small repeaters) yet literally tens of thousands
of houses in this area are aligned onto the transmitter, and for good reason, Line Of Sight ! (also see ATV`s aerial array)
The map is also fascinating for other reasons. For instance it explains why, when the first "mainline" railway (The North Midland Railway from Derby to Leeds) came to this part of the world in 1840, it didn`t come through Sheffield. At that time the locomotives didn`t have the power to climb steep gradients so alignments were chosen which minimised inclines.
A look at the map shows quite clearly how the low ground of Rother valley passes East of Sheffield and that`s precisely where George Stephenson (and his son Robert) built the line. It wasn`t until 1870 that a South bound line was constructed from Sheffield to Chesterfield
by the Midland Railway. The latter had a fairly steep (for the time) incline up to Dore, then the 1.2 mile Bradway tunnel and finally a long descent down to Chesterfield. The valleys used for the latter line are also clearly identifiable on the map.
One other thing, ever wondered why Sheffield hasn`t got an airport ? Quite simply there isn`t any room for it ! It is easily discernible from the map that the only significant area of flat
land (for the runway) in this area is the Don Valley and that has always been fully utilised. Having said that I know a few people who would be delighted if Meadowhall were flattened !

Note the M1 (which we have drawn on in black) and Crosspool TX, plus Chesterfield TX at the very bottom of the map.
From the centre of Sheffield, Emley is North West, Bilsdale is NNE, Belmont is East and Waltham is South West.
Incidently if you`re ever lost, looking at the local antennas (assuming you know which transmitter they`re on) can help you to establish which direction you are travelling in !
ATV Transmitter Map
The famous ATV transmitter map on the shop wall. This covers Wales and England (from just north of Newcastle to just south of Bristol/London) at 4 miles to the inch. We have included a sample "blow up" to show the detail, full resolution pictures are available at Transmitter Map. One area of particular interest is that of the South Peak District which shows four repeaters (Tideswell, Ashford, Earl Sterndale and Buxton) off four different main transmitters (Emley, Waltham, Sutton Coldfield and Winter Hill respectively) yet none are more than nine miles from any of the others ! We have added all the repeaters for the main TXs within the maps area in England and some (so far) of the Welsh ones. As time allows we will add all the others and the BBC radio TXs. ILR TXs may follow if we can get the relevant info. As expected there are large numbers of repeaters in the hilly areas, but hardly any are situated in (say) Lincolnshire.
The pins are colour coded for group (plus Radio are blue) and there is an arrow from each repeater to it`s main transmitter. (also see Major Transmitters: Which Aerial To Use)
