Denise: The official line is "Some viewers may also need to install a small filter at the back of their TV to prevent interference once new mobile services launch. " - Digital UK | 700MHz clearance
In theory, at least, 5G signals should be lower power than 4G. Because they use a large number of smaller cells to provide more (let's call them) connections, these have to be low power to prevent signal overloads in the very small cells.
In practice, the problem for most people with the previous set-up of 4G services was that the signals caused people's amplifiers to overload in certain circumstances.
In theory, at least, you should be able to remove your old "filter" once the clearance is complete. If you need a new one probably depends on if you end up with some channels broadcast at the "new top" of the Freeview transmission band.

Barrie Spink: There are no plans to extend Freeview beyond the current broadcast areas.
In the Scottish Highlands it is very hard to put up transmission masts that can be "seen" by domestic locations.
From the broadcaster's point of view, it's much cheaper to send the signals up to a satellite above the equator, than it is to build more relay stations on the ground.
It just isn't economic to serve small numbers of homes from ground-based transmitters when the Astra satellites can used instead.

John Martin: In fact, when they refer to "8k", it doesn't refer to the vertical resolution ("lines"), but the 7680 horizontal pixel count.
In old money "8k" would be 4320p ... compared with Feeview HD's 1080p.
Ultra HD, of course, is "4k" resolution (meaning 3840) which is 2160p. You can use UHD already with services like YouTube and Netflix.

Apologies to all, there was a fault in my code that was showing the final position for the 700MHz clearance, rather than the correct interim one of 60- 53 51 33 57 32.

Craig: Welcome, and thanks.
It appears that Sky made a special deal that pulled Channel 4HD and All4 services from the Freesat platform, which is a great shame. Channel 4 abandons Freesat HD in TWO DAYS | free and easy
I understand this is because Sky offers discounts to broadcasters who make their HD services not aviliable on Freesat and Channel 4 did this.
The fact you paid them for a subscription suggests it was a great move for Sky as a business.

t j cole: The most likely explanation is that you have a central heating system with a thermostat kicking in. It's quite common for these two be a simple electrical device that causes a tiny spark every few minutes. The tiny spark is basically a small radio transmitter.

Andrew Ripley: I guess that this whole process was always going to be like this.
It was always possible that Freeview could have cleared itself into the lower range that it will use by 2021 earlier, but it would have caused a lot of cost and disruption to an unmanageable number of homes.
There is still likely changes ahead in the next decade too.

Colin R: I guess it's worth remembering that the at800 | 4G & Freeview | 4G interference | 4G Filters | 800 MHz people have been paid for by the mobile broadband companies as part of their deals to get the former TV broadcast frequencies.
They have provided, over time, free filters and sometime free Freesat equipment, as well as the necessary support. Which you might expect as they paid 2,341m that they paid them.
The problem here is that any additional benefits from changing to DVB-T2 don't accrue to HMG, but to the multiplex owners. I can't see that Lord Hall of Birkenhead, for example, really has shown the ability to understand this kind of commercial situation, given his previous well-documented actions.
