Hi Caarlo,
Sorry for asking but have you tried cross-parallel loop configuration
with two 1m loops? Maybe worth a try. I have commercial LZ1AQ, so I
can quickly click relays and see the differences. In my situation
(loop is outside on the 2nd floor balcony) I see almost no difference
between LoopA vs LoopB, but there is a difference between A+B vs A or
B. Yes, both Signal and noise go up with A+B, but a still can see a
bit of SNR increase.
Regards,
Simon

Ok, I guess I am losing the battle.
Last night I tested a smaller loop (0.5m diameter) hoping that the lower pickup level will increase linearity and improve SNR. But SNR did not change. Pickup levels were 10-15db lower, both signal and noise, so SNR remained the same. Tried different locations and orientations, but none produced better SNR than my full size antenna.
Placing the loop horizontally worsened the SNR. Of course this was 1.5m above ground perhaps. Could not clamp it to the tower yet.
FInally, almost hopeless, I placed some ferrite snap-ons, on both ends of the cable, but this did not help either.
