There's a lot of spam getting through again, I don't know if you can do anything about it.
Deleting some of it would help!

Hmm, well, is the postcode you've given where you'll be wanting the reception?
If not please give the relevant postcode.
Whilst you've posted on the Gulval relay transmitter page, the predicted signal at the postcode you've given is variable (not at all good tbh) even though the transmitter is only 2km away, vertical polarisation, at compass bearing 232 degrees (roughly SW), it's a very very low power (5W) relay with only the PSB multiplexes.
A far better (good) signal from Redruth 21km away, (horizontal polarisation) is predicted, at compass bearing 71 degrees (almost ENE) and has all 6 multiplexes. 20kW for the PSBs & 10kW for the COMs.
As far as that aerial goes, they claim it has a gain of 3dB (not much) certainly not high gain. It's omnidirectional so will pick up signals from all directions including reflected ones. And as far as all the other waffle/rubbish goes, ignore it. A 50 mile range !! that will depend on the power of the transmitter you're going to receive. Aerials are aerials they pick up RF signals, they don't care if they are analogue, digital, HD, SD and there are no 4K transmissions in the UK! As far as "optimised for digital" what rubbish.
As you say, it's cheap, so if you want to give it a try, please do. BUT it ought to be external and have a clear line-of-sight to the transmitter - no trees or other caravans etc in the way.
Frankly, if it's TV reception only, you'd be far better off with something like this -

This is of course an external aerial which will require some sort of pole mounting. You'd need an F-connector for the aerial end, some low loss double screened coax and a coax plug for the TV.
It will receive signals from any UK transmitter where the signal is good (as it's group K which also has protection from mobile mast interference).

Elizabeth:
The Carmel transmitter was listed at the beginning of the week for Planned Engineering -
Carmel transmitter: Possible effect on TV reception week commencing 10/06/2024 Pixelation or flickering on some or all channels [DUK].
The work may be continuing and this MAY be the cause of your problem but we need a full postcode to check your predicted reception and check for possible interference.
Have you at anytime whilst you had Pixelation or No signal tried to retune?
If so, please advise, and do NOT try to do so in the interim.
