Dentron MT-2000A and MT-3000A
These are efficient antenna tuners capable of handling full legal limit power for use with amateur radio.
- Freq Coverage: 1.8 MHz - 30 MHz continuous
- Power Handle: 3000 watts P.E.P.
You should connect only one antenna at a time to the MT-2000A. The MT-3000A will accommodate multiple simultaneous connected antennas.
Although you can physically connect an antenna via the PL-239 and another antenna via the balanced line connector to the MT-2000A, you should not do this as there is no way to select between them from the unit and consequently you will have problems.
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.
(A) on the inductor is the highest frequency and (R) is the lowest frequency on the inductor switch.
