Inductor Guide

Inductor selection is a starting point for you to tune to resonance with your own antenna setup.

Dentron recommends setting both capacitor selectors (Transmitter Matching) and (Antenna matching) to setting 5 before trying to locate the correct inductor setting for the frequency. Watch for the highest noise/signal level on the S meter. When the best inductor is located then fine tune using the capacitance tuning dials.
