Regenerative loop antenna

The regenerative loop antenna can consist of a tuned signal winding on an open X frame with a feed back winding in close proximity. High effective gain is achieved, for example by placing this feedback winding in the drain circuit of a JFET (junction field effect transistor). An antenna of this type employing vacuum tubes was constructed by Vladimir Zworykin in the 1920s.

gollark: -generate 6x6x6 efficiency no cryotheum no enderium
gollark: Ah yes, it does work, just with a Windows XP-looking GUI, but meh.
gollark: Good to know, thanks, I'll run it then.
gollark: The Hellrage one or whatever it is doesn't, as far as I know, run on Linux.
gollark: It would also be nice to have an item list, actually. I can count them manually, it's just annoying.
