Denis:
Thanks for the update, albeit a few years :)
The transmitter aerial will be the same antenna, so this will more likely have something to do with your reception rather than transmission - unless they are doing engineering work at present, I'm afraid I don't know of any reliable source for possible engineering information on Saorview masts.
You say that the aerial is on your balcony. so its reception could easily be frequency dependant depending on the surrounding building and balcony structure.
Have you thought about trying to reposition it slightly, or angle it upwards slightly. See if any of that makes any difference.

Steve Donaldson:
Thank you so much for that Steve, I didn't have time to go hunting around previously.

I'm afraid I can't answer your question about the BT TV Box, but one thing you could do is check your cables, flyleads, interconnecting aerial leads etc and make sure they haven't gone faulty - breaks etc.
Should you need a filter, then it would be a "5G" one - ie. a 700Mhz one (it also deals with 4G).
If you have a NI postcode you can get a free filter from Restore TV, check here -

Old Coulsdon is a relay of Crystal Palace, the latter being listed for Planned Engineering so whether this is having any effect is anyone's guess (It shouldn't IMHO), Still worth checking things out with Restore TV.

Stephen Dyer:
I presume you have checked that you are tuned to UHF Ch47 for PSB3 from Old Coulsdon and not inadvertently tuned to UHF30 which is an SFN used by Crystal Palace and Reigate.

First thing to note is that Oxford is currently listed for Planned Engineering, so that could be having effect on your received signals, so maybe don't rush to change things.
As you haven't given a full postcode, I can only do a check on a random one in Kidlington, and therefore I assume the aerial is now pointing somewhere around compass bearing 113 degrees roughly ESE with its rods horizontal.
The fact that you are having high errors on C31 - 554MHz (ArqB mux) and finding lower strength on C29 - 538MHz (SDN mux) might suggest a fall off in aerial response BUT the engineering work MAY be the reason.
Because of your general location you should be getting signals for the Local Mux (LOX), it transmits on two UHF channels from Oxford depending on where in the service area you are, but you should get both!
Have a look at C22 - 482MHz which should be slightly stronger than C46 - 674MHz.
There's also another possibility and that's interference from a new/upgraded mobile phone mast now using the 700MHz band. The property may have been sent a postcard from Restore TV, but sometimes we find they haven't sent to all relevant postcode they should have. Check here to see -

Even if it says NO, it could still be worth getting onto them if problems persist, to get the Free Filter.
Should you find a change of aerial is needed, then yes Group K is now the correct aerial for all TV transmitters since B700 clearance. If you want a "flatter response", then you might want to consider a Group K Log periodic (yes they are made!) Toolstation did have some.
But whatever aerial you get, make sure it is a Group K as anything with a wider bandwidth (Group T / Wideband, even Group B) with response above C48 will leave you potentially vulnerable to mobile band interference.

On the Kilvey Hill Freeview transmitter page, a duplication of the Freeview engineering information is posted -
Kilvey Hill transmitter: Possible effect on TV reception week commencing 03/11/2025 Pixelation or flickering on some channels.
There could have been similar on some previous weeks but I can't check at the moment.
As you haven't given a full postcode, we can't comment on your normal predicted reception which may already be vulnerable to reception problems or some interference.
