And just to be absolutely clear, because of the capacitive coupling, there is no DC loop circuit from the cable end through the dipole. The pcb is screwed down to the ends of the dipole loops with self-threading screws.

Indeed. The real frustration is knowing that we used to have at leat useable reception on this channel. I didn't give you the full picture of my efforts yesterday but I took the dipole assembly off (it's only a plastic clip) removed the cable connection and pcb, cleaned and reassembled it all. The 2m cable run looks undamaged. I checked the alignment of all the elements (talk about clutching at straws). It all looks great, as you'd see if we could post photos.
Like you, I have to suspect the aerial but really can't justify the effort of replacement when it all looks so new. We are only 5km from the relay and the terrain profile shows nothing between us and it, other than the odd tree.
I would consider reorientating to Sutton if it weren't for the desire to get East Midlands news. Despite the alignment differences, I seem to get a significant signal from there! Walton isn't an option as there is an undeniable topographic obstruction in that direction.
Anyway, many thanks for your time and thoughts. I'll go and fix something I can fix.

I'm going to clamber into the loft again and try swinging the aerial round to Waltham to see what I get.
Desperate times, desperate measures.

I thought I had replied yesterday but I can't now see that post.
It was just to say that out of sheer frustration, I am going to try pointing the aerial at Waltham - we want E Midlands options.
The aerial looks fine and all connections measure as perfect. There's ;its;e else to do.

Apologies for the delay since April! Other issues crowding life and a certain degree of sloth around this particular problem - noli nothis permittere te terere and all that.
I've currently given up with Humax support - like you I'm convinced it's a problem with the Aura (only 9 months old) but, as they can't guarantee that a full reset of the box will retain my recordings (they "think" it will be ok!!) I haven't had the nerve to try it. A full retune with a cleared memory doesn't fix the problem.
In the meantime, I'm content to use Quest+1 - the problem seems to be solely on COM6.
Thanks again

Yes, that is the same basic aerial - the version I have, because of its age, doesn't have the inbuilt 4G filter. The one I'm using was supplied by the project (Televes 404401).
I have checked all the connections. The cable terminates on a balun pcb which is capacitively coupled (through the pcb varnish layer) to the dipole. The cable from the aerial to the splitter is only two metres long so, although I have checked end to end continuity, the loop resistance is well below my measuring capacity.
Whilst up there I also checked the aerial alignment both vertically and horizontally to verify that it is pointing to the Nottingham relay, based on the published latitude and longitude.
You can see why I'm getting exasperated.
