FIELD_STRENGTH_METER

Useful for antenna experiments and ad justments in amateur bands from 160 to 10 meters. Increasing size of pickup antenna increases sensitivity. Far-field measurements are made with alternate input circuit, in which reference dipole or quarter-wave wire cut for frequency of interest is connected to input link. Diodes are 1N34A germanium or equivalent. M1 is 50μA. Table gives values of tuned-circuit components for six amateur bands.-D.
