Great job! I like how you did the feed on the pick up loop. Makes a nice simple coax connection. The design looks fairly waterproof for use outside in rainy conditions. Nice, 73
Bob - Looking at this video I'm guessing it's a 350pF variable capacitor. It's very wide spaced so (total guess) it might be 3kV or so. I might be completely wrong here, but I hope tat helps./
