Postcode to TV Transmitter Tool
Enter a UK postcode and we'll show you the Freeview transmitter serving that area, the compass bearing your aerial should point, the channel group and polarisation, and your nearest installer.
That doesn't look like a UK postcode. Try again.

How this tool works
- Your postcode is matched to its postcode area (e.g.
NG1 2BB→NG). - We look up which main UK Freeview transmitter serves that area, based on our directory of 50 UK transmitters.
- The compass bearing is calculated by great-circle geometry from the area's main town to the transmitter's coordinates.
- The channel group and polarisation tell you which type of aerial to fit and how to orient the elements.
Coverage edge cases (Surrey relays, Scottish islands, terrain shadow) won't fit a single postcode-area answer perfectly — for those an on-site signal survey is the only honest answer. See our full transmitter directory or Freeview's official channel checker for granular detail.
