The usual advice if changing an aerail is to fit a log-periodic type which is not 'grouped' as it covers the whole frequency range used currently and in future for Freeview transmissions. Depending on your location and reception conditions, you can get log-periodic aerials from 12 element up to 72 element, so they would cover the needs of most areas. That would laos mean that any future changes that are foreseeable currently would not mean the aerial needs to be chganged again.
If changing an aerial, do not fall tfor the con of a 'digital' aerial, there is no such thing. I would also urge taking not of that said by StevensOnln1 above.

There is no such thing as 'Sky+' cable, it is a marketing ploy to charge extra for good quality satellite cable. All you need between the LNB on your dish and any receiving equipment is good quality satllite coaxial cable, not 'standard' UHF TV cable. I use either CT100 of RG6 as a minimum, but you can get lower loss cables at greater expense. As you cable run is just 20 metres you do not need ultra low loss cables.
The likely cause of your problem is either a poorly fitted F connector (with a piece of the outer shield touching the inner core), a failure of part of the LNB (though these are rare) or a failure of the receiver equipment. You say yopu've tested the box on the other signal feed, so check the connectors are both fitted correctly with no short circuit between inner and outer conductors.

Please provide a full post code so that we contributors can look at the reception conditions at your exact location.

The uk UHF TV frequencies will range from 450 MHz to 699 MHz after the 700 MHz changes so a lot more space than you suggest. That encompasses Band 4 but in the future Band 5 is being sold off to the mobile operators, etc.
Many rural areas still get attrocious broadband speeds. Where I used to live the maximum quoted is 1.25 mbps which is far too slow for streaming anything let alone TV services. So don't think that 'everyone' can get the USO of 10 mbps for many years to come.
I don't think all TV services will use the full bandwidth available with 256QAM and radio services do not need anything like as much as TV does.
'HD Ready' only refers to the screen being able to display at 1080P, Freeview HD refers to eqwuipment that can both receive and display HD services. 'HD Ready' cannot receive the signals and decode them into sound and picturte.
DSO was not a 'con' in my view.

You haven't given a full post code so we have no way of checking what you should receive.
It seems likely that your TV has selected the wrong transmitter so you will need to do a manual retune. Check on this website which channels are used by Emley Moor and then look in your TV User Manual for how tro do a manual retune.

To do that we need a full post code for the location where you are trying to receive TV services.

Tricia:
What type of aerial are you using? The main channels from Tacolneston are on 55, 59, 50, 42, 45 and 39. COM7 is on 31 while COM8 is on 37. It could be that your aerial, though probably of a Group C/D type, may not be good at receiving channel 31, it's right down at the bottom end of the band.
One possible sollution is to have your aerial changed to a log-periodic type which will cover all the channels you should receive and will be suitable for the foreseeable future.
Hope that helps?

I suggest you ask the actual broadcaster of that service. This website is entirely independent of all broadcasters, being intended for technical reception assistance, so no one connected with this site has any idea.

Tom:
COM7 and COM8 have always been a temporary solution to a lack of spectrum, so when the channels and multiplexes are reorganised they will no longer be needed as the channels they currently carry are intended to be moved to other multiplexes. That means you do not lose any services unless the broadcaster decides to cease transmission.

It rather depends on what your signal strengths are at present. Ideally you need strengths between 50% and 85% for SD channels and between 60% and 85% for HD channels to get reliable reception. Too much and too little will cause loss of signals. Your TV User Manual will tell you how to check that.
Normally we would get a set of link boxes underneath your posting, but I noticed that your post code is not in the correct format, I suspect there is an extra digit.
The usual advice, if an aerial needs to be changed, is to fit a log-periodic that will cover all current and future planned transmissions as far as is known at present. I suspect that at your approximate location a Log36 would be sufficient with the rod vertical and aimed carefully towards the transmitter. I'm not sure whether there are any obstructions between you and the Rowridge transmitter.
By putting SO21 1TG into the page at https://ukfree.tv/prediction shows your are well served from Rowridge and should not have any significant reception problems. That predicition does not show the terrain between you and Rowridge though. If you put the correct full post code into your posting it should show the terrain mapping.
