How far it reaches
Two different questions, and the map below can be switched between them. Reaches is everywhere this mast puts a usable signal; strongest is the much smaller slice where nothing else does it better.
| Band | Reaches | Strongest in | |
|---|---|---|---|
| Television | 3 of 238,895 Output Areas | under 0.1% of UK Output Areas | a relay, serving a local area |
More detail
Most places can receive several transmitters — a median Output Area hears twelve — and only one of them can be the best, which is why the two columns are so far apart. Reach counts an area once the model clears the reception threshold there at all, and it inherits the sweep's screen: only the strongest twenty candidates per area are stored, so a mast lying twenty-first somewhere does not count as reaching it. Both are a share of areas, deliberately, and not a number of homes: checked against Ofcom's own coverage the model ranks transmitters correctly (Spearman 0.861) but over-states how far each one gets by a median factor of 2.5. A share is a ranking statement and survives that; a household count would not. How this is worked out.
On the map
Everywhere Aveton Gifford is predicted to reach for television, shaded by how much signal is left over. Other transmitters reach most of this ground too.
Only the areas where Aveton Gifford is the strongest option for television — the ones the postcode lookup would send here. A smaller picture than its reach, and a different question.
The model predicts too few served areas from this mast to trace a coverage edge, so no rings are drawn.

Other transmitters nearby
Every structure Ofcom list within 40 km, nearest first. Close is not the same as an alternative: most of these are single-service relays, and one of them may radiate a thousandth of this mast's power in a direction that misses you.
