Wideband active small loop antenna edit / delete

Lower a loop's Q by adding resistance, then build in an amplifier: wideband magnetic-field antenna. Worth building to compare to my PA0RDT electric-field probe.

Including investigations into multiturn loops. (Aegis on #hamradio.)

And multiple kites. And aerostats. Wow.

Lots of random electronics: radio, including an unusual loop antenna; simple computer designs; why ECL should have beaten TTL; and various other bits.

Thought I'd bookmarked this before -- hm. Good stuff on antenna tuners and feedlines.

Why high SWR and feedline radiation isn't necessarily a bad thing (because it doesn't actually cause much loss in practice, and it lets you tune the antenna from the transmitter end).

Building a continuously-loaded short vertical antenna. I think I need an antenna analyser in order to reproduce this...

I like the stacked double loop antenna.

Neat -- a printable reflector for wireless network antennas that gives a bit of gain and directionality.
