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.)
