DVBT Signal- BGT3540 v BGT3595?

[Wheeker]

I'm getting the attic converted so have had to lose my attic DTT aerial . Always got c.70% signal on WMC (W10), though now & again got pixelation, with my Blackgold BGT3540. I installed one of these aerials instead https://www.satworld.ie/revez-t80-clip-on-aerial.html as it's discreet & clips onto Satellite dish which is roughly in direction of nearest transmitter. Was assured by shop that it would definitely work in my area. So now I'm getting 1% signal which fails now & then and freezes! Thing is, my TV inbuilt tuner gets a great signal no problem? Does WMC have lower tuner sensitivity than standard TV tuners? I also have a BGT3595 I was going to try- would the DVBT sensititvity be better with this card? (N.B. Ireland transmits HD DTT via DVBT not DVBT2). Otherwise will have to rethink my aerial solution.....

So swapped the BGT3540 for the BGT3595. Ran Clean Set-up using EPG123. I get no channels detected for DVBT. If I plug the same aerial cable into my bog-standard LG TV- all channels are showing perfectly! Is this WMC DVBT tuner sensitivity just rejecting the signal as too weak, even though it's fine for my TV? Is there a way to change it? I also have a TBS 6280 I could try, but it seems to me this is a WMC software issue & if I want to continue to use it for DVBT I will have to go back to a bigger aerial.

So just to update in case anyone was following this (or am I talking to myself?!). I kept trying EPG123 Clean set-ups until I finally, somehow, detected some DVB-T channels. Signal Quality was 1% though? Then one day, for no good reason, signal quality on all DVB-T channels changed to 100%, perfect picture, better than I ever had before with the attic aerial! Not sure if switching to the BGT3595 made any difference or not, but a good outcome anyhow. Also now I have 4x DVB-S2 tuners.
