I agree with Fred. Had trouble with a Mosley trap years ago that had dirt
from spiders causing a short which eventually led to arching. As Fred said,
check the screws that attach the trap to the aluminum. Rust and corrosion
was the culprit. Had severe arching there one time. Thats what you get for
cleaning those traps for years on end! BTW, mine were all in the driven
elements. The best medicine for the antenna is to completely disassemble all
the traps and clean it up. I used a brass bristle brush to scrub the trap
coils and replace the screws with stainless steel. While you're at it clean
the aluminum joints and coat with Penetrox.
