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.)
