Loop for lower-frequency amateur bands is connected to gate of HEP802 FET and output to receiver istaken from FET source.C1 is two-gang variable capacitor from old broadcast radio, with stators in parallel to give 600 pF. Article gives loopdata for 40, 80, and 160 meters and for high end of broadcast band. For 40 and 80 meters, use 18-inch square loop with 2 tums spaced 1/4 inch. Ground lower end of 100K resistor to provide ground retum for FET.-K. Comell, Loop Antenna Receiving Aid, Ham Radio, May 1975, p 66-70.
