Of course we can't know what's causing the noise, but the SN for the air-core loop is higher on both frequencies, not to mention the huge increase in SSI. A 20-24 dB increase is much higher than I would have expected. The 360 clearly likes your air-core loop, and it's worth trying to sort out the noise issue.

I'd like construction details on that air-core loop. Any chance you can post a photo? Thanks.
