Re: Not even 5g
What do you think the reason was for switching from analogue TV to DVB-T? It was to sell all that lovely bandwidth to the mobile phone operators.
Notice the bands at 450, 700 and 800? Not all of those are used in the UK, but 800 certainly is.
Either way, it's all UHF. Your body is unlikely to be affected by 900MHz and not by 800MHz -- unless you fold your tinfoil hat very carefully!
