| 10 hours ago | comment | added | TimWescott | I think you need more clarification, because Andy and the other Tim are giving you answers as if you're asking about the difference in conduction inside the tube and outside the tube, not the surface of the tube toward the center of the antenna and the surface of the tube toward the outside of the antenna. That's what I thought you meant. I'm now 99.44% sure you're talking about inside the antenna, not the tube. However, usually when you tell an RF guy "inside" and "outside" and there's a tube involved, that's what they're going to think. | |

I mean a naked one-turn loop without any other shenanigans, a variable HV capacitor between both ends of the conductor, and a smaller coupling loop at the other end of the circle, where the RF power is fed to. | |

| 13 hours ago | comment | added | TimWescott | I think you mean an antenna like this one -- but I'm also pretty sure that the one answer so far doesn't speak to that design. You need to edit your question for clarity. I suggest that you drop a picture of the antenna design you're talking about (the page I cite here has an excellent one), cite the picture properly (by linking to the page it comes from, for instance), and see if any answers change. | |
