Wideband active small loop antenna
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).
Homemade HF - antennas for mobile operation 7Mhz ,10Mhz, 14Mhz, 18Mhz, 21Mhz, 24Mhz,28-430Mhz
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.
