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. If tuning for the higher bands 20, 15 and 10 set the "transmitter" capacitance to 8 instead of 5.
(A) on the inductor is the highest frequency and (R) is the lowest frequency on the inductor switch.
