You'll need to show me what you mean and how it's done some day. I'm dumb about electrical stuff
Something like this:

They're basically gas filled devices, you get anything more than your normal signal levels (aka lightning) the gas inside ionizes and conducts like a neon sign.
Huh, first time I've ever seen that. Most of the designs I've seen in ghetto ham sites shows a wire that has like a splice to a spike driven a few feet into the ground.
Not that it matters regardless. My little tecsun is broken and I can't afford a new radio, nor is there much to listen to in the US anymore, especially where I'm at
Some types of antennas do need an "earth" ground to work, but this device goes between the antenna and your receiver. It only comes into play when the potential between the incoming line (your radio) and ground (the case) exceeds a certain value. Otherwise, it's just a connector.
