Has anyone here read the November article on using the feedline portion of a doublet as a noise antenna for phase cancelling QRM? I am still trying to puzzle out how it might work, and under what conditions, and how well. Wondering if someone has built or analyzed anything like this. The author describes quite dramatic improvements in SNR for signals up to a few hundred kilometers.
