I've noticed the exact same thing with my EF-515 & EF-420/240 antennas.
It usually happens as a storm front is approaching. It even causes a little
static in my TV & stereo. I haven't turned on the rig to see how bad the
noise is then.
I went out one night when a storm was approaching and I could actually see
arcs at the element to boom clamps. Looks like the charge is arcing across
the PVC insulators of the F-12 antennas.
Is the arcing going to hurt anything??? Is there anyway to stop it?? It seems
like the antennas would be nearly un-useable with the kind of noise this
