Ian GM3SEK referred me to G4WIM's article in Radio Communication Nov'1986 "A 1-8 MHz Auto Tuning Verical Antenna".

Magloop's capacitor could be tuned just as well, I think. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
