Only under inclement conditions where the antenna is
actually discharging corona. Otherwise, it is just mostly
A closed loop antenna does not have points sticking way out
like a dipole (hence streamers in the loop form at higher
charge levels). If it does have corona although it would
still be noisy it is unlikely to be at a high impedance
point that would maximize noise.
I doubt many people would notice the real difference, so it
is probably either that the guy got lucky and the antenna
nulled whatever noise he had or more likely just
