Antennas Radios Amplifiers Baluns and Receiving Systems for HF edit / delete
Lots of interesting stuff -- particularly on antenna design and implementation, with common assertions tested in practice. The pictures of his setup are highly entertaining; I've seen smaller broadcast stations!

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?)

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...)
