9.9/10 from 64 reviews
London’s main TV transmitter, run by Arqiva, serving Greater London and parts of the Home Counties. It stands on a hill in south London, and the mast is over 200 m tall.
Rods lying flat (it broadcasts horizontally), a group A or wideband aerial, channels 22, 23, 25, 26, 28, 30, and 35 for London’s local channel. Which way from your postcode
Your aerial may be pointed at a smaller relay transmitter; relays usually carry only the multiplexes with BBC, ITV, Channel 4 and Channel 5. Freeview’s checker shows which one serves your address.
The direction is only part of it: a loose cable or a faulty booster can cut the picture too. An engineer tests the signal at your home with a meter and puts it right.

On a hill in Crystal Palace, south London, in the London Borough of Bromley; the mast is over 200 m tall. It is London’s main TV transmitter, run by Arqiva, and serves Greater London and parts of the Home Counties.
It may be planned work on the transmitter: check Freeview’s weekly list. During the work, don’t retune: the channels come back when it ends. If a neighbour’s TV is fine, the fault is more likely your aerial, its cable or the TV.
A group A or wideband aerial, with the rods lying flat: Crystal Palace broadcasts horizontally. Our transmitter checker gives the direction from your postcode.
UHF channels 22, 23, 25, 26, 28 and 30 for the national Freeview multiplexes, and 35 for London’s local channel.
Those changes finished in 2020. The Crystal Palace main transmitter’s six national multiplexes kept their channels.
Only once any planned work has finished. Then, on each TV: Menu, Set-up, First-time installation, OK (Freeview’s steps). If channels are still missing after a retune, an engineer can find the fault and fix it.
