No worries, picrel is the 60 cm tall multiband indoor antenna that feeds it, I'm the only multiband monitor within 500-1000km now for some reason, maybe digimodes aren't cool anymore?
My last base antenna was 50m to the tip up a tree and the coax went over and touched the gas pipe to the house along my bedroom. Thankfully lightning is rare but you could hear and see it build up in your radio before a lightning strike occurs.

I've had tube testers, tube radios, tube signal gens, tube oscilliscopes. I fucking hate tubes and refuse to work on that shit. Through capacitance or whatever you still invariably end up getting shocked when it comes to RF, even with massive cables to their chassis ground going 3' to a 10' groundrod in wet earth filled with electrolyte clay.
Play it safe and only work on tube stuff with one hand behind your back at all times.

High voltage is weird. I built a bugzapper boost voltage ladder circuit and the multimeter voltage at the end read 0v after I had unplugged it and let it rest for a few hours. It still made a massive spark when shorted and was obviously well above the voltage reading abilty of my meter.
