Question about optimal H-field antenna placement for noisy urban areas

If you can pass that self-inventory, etc., go for it.
Now, that's an older post, and Dries doesn't reference the newer mini system. But that doesn't matter.
Blue mini only has 2 H field channels, No E channels.  Otherwise things are virtually the same as the docs he links to.
(Those are the ORIGINAL docs... there have been many upgrades, etc since then, but I'm not posting any links. These basics haven't changed.)
STUDY THEM
then, might peruse this more updated version... https://docs.lightningmaps.org/station-operation/

'Noise' is somewhat relative anyway.... as long as you can get an impulse signal > twice your noise level, with ADC trigger at twice the average noise level, the controller will (generally) send it. It likewise will send any noise junk above that threshold. The receiving server takes over from there. (where the noise analysis and Sig/Noise level is reanalyzed using more complex algorithms).  The problem arises from TOO MANY SIGNALS, then the controller hits 'interference mode' and stops sending ANY signals.  These 'signals' don't have to be 'noise'.  A cell can have so much activity that the signals are all mixed together, too strong, whatever, and the controller will also go into interference mode.
