Sorry to hear your having problems. My only input would be to lay the wire on the ground rather than raised and attached to the fence. Admittedly your installation is not that high off the ground, but I understand that as the loop is raised in height the polarisation becomes horizontal rather than vertical. If anyone reading this is considering buying a LOG kit, I would suggest buying from Radio-Stuff. Their kit including 20m of wire is £19.49 delivered.
I feel your pain. Its a struggle trying to set up a decent functional station in what looks like a typical small urban site. My first observation was you are trying lots of different things simultaneously so multiple wires and poles and feeders in situ. All these things interact with each other, even if not being used, even if not intentionally part of a antenna system. This interaction draws the noise or unwanted signals all over the site. Ground loops require a "clear" area of ground to work correctly. "clear" including in the context in radio current conducting things. So things like the QRM killer wire might be getting in the way just being there. Or its just proximity, your main end fed is inducing the noise its picking up into the ground loop. I know when I tried comparing two antennas simultaneously and switching back and forth I often saw little difference and it took years til it dawned on me the two antennas coupled together and ended up with pretty match the same signals! A personal opinion, end fed antennas. I dont get it, I dont rate them. I think they are a fad. Lots of chatter on UA-cam resulting in people trying them and finding the basic issue that unbalanced antennas are a PITA to actually use! Do you have all the balun/common mode choke malarkey in place? Is it working? Are you fooling yourself by hiding a basically nonfunctional antenna behind a tuner? 73 de G0AFV
Ive just moved my end fed up a mast so the transformer is 30ish feet in the air, it slopes down a bit to 5m after about 15/20m then comes down to my front garden, hoping this brings it away from the loop on the ground. Not going to give up got lots of testing to do

Antennas are not called 'aerials' for nothing.
