Please could you tell me why ITV4 and Film4 are not sent to the Assendon transmitter and if they ever will be.Many thanks.

S Brown: No, Assendon isn't likely to carry the Commercial multiplexes, which carry ITV4 and Film 4 among others.

The reason is because the Commercial broadcasters do not have a "Public Service" obligation. They operate purely on a profit-driven basis and cover 90% of the population from 81 of the largest (by viewer population) sites. To include the 1,000 or so small relays including Assendon would roughly double their cost of transmission whilst only adding 8.5% of the population to their potential viewer bases.

Unless you can receive the Commercial multiplexes from another transmitter such as Crystal Palace or Hannington then you won't ever get them.

Freesat may be worth a look for you.
