What you might do is run just one loop for testing, then you can null out the strongest noise offenders with a simple azimuth change. The loop configured as you have it isn't going to be able to null out much of anything, as it is now more or less omnidirectional. The ability to null is just about the loops greatest selling point far as I am concerned. It would be nice to have either a rotatable loop or two fixed loops that could be selected at whim to enhance sigstrength and/or to reduce qrm/n. Also make sure there's no noise being sent up the line to the antenna from the home because that can happen, a ferrite core or two at each end of the line should take care of noise along the line. A buried line should have little to no noise on it for obvious reasons (moles, earthworms, and grubs are stealing wifi from it).

Not long ago, I ran two turns of speaker wire around a window frame inside the house to feed to a nearby Icom R75 on its hi-z input just for giggles, twisted the wires together to secure the loop and act as a twin lead feed line that was about 4 feet long. Worked great from vlf thru hf, but it did pick up qrm from the also nearby pc in the room. If a band was open, this antenna heard it. That experience is giving me motivation to roll a 1m loop in the yard up about 20ft or more, sans amplifier, but with a 3:1 balun (5 turn pri 3 turn sec on mix 77 core is close to 3:1) and some ferrites to keep rfi off the rg11 feed line, then into a distribution amp that has about 5dB gain. Aiming it to eu, the intended target, should also null out some noise from the house.
