Interesting idea for lightning protection. If you are trying to bleed of static charge to prevent a strike the bolt end(s) should be sharpened and the ground conductor very low resistance to ground. A ball end on one bolt and point on the other should also work better than just blunt ends. For 100W operation you could probably get away with a 2mm air gap. I'm sure there is a calculator and formula for air dielectric arcing probably on a small loop or engineering website.
Are Hams finding by adding a wire to the ground side they get improved SWR and performance of the antenna as it begins to look like a dipole antenna as well as an off center fed antenna. I'm wondering if the ground wire also lowers the feed point impedance a bit.
NOT an antenna for beginners, a dipole is. End feds work very poorly, they are high impedance, poor distance and noisy. Balun / unun myth. Baluns and ununs are NOT for antennas, they are for coupling transmission lines together. Seemy antenna videos for proof
I like your idea of the bolt spark gap. Maybe a high value capacitor across the gap would allow high voltage to leak away.
I'm wishing your friend a lot of success with learning for his license.
Nice video. Great to see your assistance to a new amateur candidate. Wishing him good luck.

I always like your work.
Nice clean work, congrats.

In the input "TX" is a low voltage.1-1.5kV capacitor enough.
Better have it more than less 😄
@@OM0ETIt is especially actual for power of 5 Watts when output voltage is about 15 Volts.😜
The 2 bolts close together might act like a capacitor to ground?
always watching
Nice FB
What size box/enclosure do you use?

Rubbish. You clearly have never used one correctly.
You R Great From ST2KI/7Z1FA🎉
