A Hexbeam in 3 hours edit / delete
Cute. I find myself wanting to hang washing on it, though.
Low Freq. Antennas edit / delete
The active loop design looks interesting -- use a high-bandwidth differential amp rather than a matching transformer, with a varicap to allow remote tuning. (Wonder how small a loop you can get away with?)

Good (extremely skeptical) article on "How the Microvert Works", and lots of radio history stuff, with some cool photos.

The Ultimate Guide to 11 Meter CB Antennas edit / delete
A surprisingly good reference to antenna design from an "11 meter" enthusiast. (This being one of those bands that has wavelengths long enough to make antenna design nontrivial, but not so long that you're always compromising...)
The G4ILO Wonder Loop edit / delete
He comments that he's only been able to measure the performance on 20m/30m/40m. Having built his design, it does indeed only tune from about 6MHz-18MHz. (The CARC design with a 1m loop and a gamma match is more like 9MHz-30MHz with a 30-275pf capacitor, so this one wins on being able to do 40m but loses 15/12/10.)
