Is the ground wire on the back of the tuner, going to a ground rod, enough to bleed off electrical build up? If there is a DC path to ground from *BOTH* sides of the dipole, the answer is yes. But, looking at the 989c schematic, I don't see a DC path to ground from one of the balanced line outputs. I forgot to say that your high humidity probably provides a path to ground from the other tuner terminal. It was only during super low humidity conditions in the Arizona desert that I experienced the arcing process during high winds. I can't recall seeing any gap-sparking here in the San Antonio area. When it's hot, it's usually pretty humid, too. bob k5qwg |
