Being a non-scientist, how does the main mast work? In particular, where does it receive the signals from for onward transmission?
Do you know, I’ve never considered that. Just googled it and it doesn’t appear obvious on there either.
Is that anything to do with Freeview going off air just after midnight a few times earlier this year?
I'd guess (now) a very high bandwidth internet connection from the central broadcasters with multiple redundancy channels for resiliency. That has probably changed over the years since it was first built.
Hi. In a nutshell, the mast basically broadcasts the signals to both homes and some child masts, which then also broadcast to make sure maximum coverage. The signal comes from the transmitter halls on the ground with the cables running through the inside of the mast. Content is provided to the transmitter halls from the studios through the multiplexes, so the distribution could be through the cloud or line fed.
No, that would have been down to individual faults somewhere in the process. The temporary mast was constructed as part of clearing the 700mhz frequency and installing new kit. So when transmission was switched off on the permanent mast, we could continue to broadcast. Now all the work and kit has been installed on the permanent mast, all transmissions are now coming from there making the temporary one redundant. So it is being dismantled next month.
