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.

As you program frequencies into the BC125AT scanner, those channels will automatically unlock themselves.
(A) on the inductor is the highest frequency and (R) is the lowest frequency on the inductor switch.
The following guide is for an Inverted V 66½' on each leg @ 45degrees for 75-meter
FOR UP TO 10 MHZ: Set both capacitors for mid range (5). Adjust Inductor for maximum receive signal or background noise. Apply less than 100 Watts and adjust for minimum SWR.
FOR 14 MHZ AND ABOVE: Set both capacitors to 8. Adjust Inductor for maximum receive signal or background noise. Apply less than 100 Watts and adjust for minimum SWR.
MT-2000A specific
It is important to understand that you should not connect two antennas to this tuner at the same time. It was not designed to have you connect an unbalanced feedline to one antenna while also having a balanced line or long wire antenna connected. Use one or the other, not both at the same time!
Building a transmatch that covers 160 through 10 Meters is a challenge. The capacitors have to have a maximum capacitance sufficient to function at 160 Meters. This makes it difficult to achieve minimum capacitance values to work at 10 Meters. You may find that the small vertical coil in the front of the cabinet can be adjusted by spreading its top two turns. This may allow better match on 10, 12, 15, AND 17 Meters. Be very careful you do not stress the switch while making this adjustment. Support the connecting wire to the switch with pliers to remove the stress from the ceramic switch.

Dentron Super Tuner Plus Manual
- SWITCH POSITION A for lowest frequency (160 Meters)
- SWITCH POSITION R for highest frequency (10 Meters)
- NEVER ADJUST ANYTHING WITH FULL POWER APPLIED except for tuning capacitors!
- NEVER APPLY POWER WITH LIGHTNING PROTECT SWITCH SET TO PROTECT. ALWAYS SET IT TO OPERATE BEFORE TRANSMITTING AT ANY POWER LEVEL!
- TUNER-BYPASS SWITCH ONLY AFFECTS COAX CONNECTOR. It does not function on open wire or balanced connections.
- NEVER CONNECT MORE THAN ONE ANTENNA TO THE MT-2000A.
- FOR UP TO 10 MHZ: Set both capacitors for mid range (5). Adjust Inductor for maximum receive signal or background noise. Apply less than 100 Watts and adjust for minimum SWR.
- FOR 14 MHZ AND ABOVE: Set both capacitors to 8. Adjust Inductor for maximum receive signal or background noise. Apply less than 100 Watts and adjust for minimum SWR
Notice above where it says, 'The TUNER-BYPASS SWITCH ONLY AFFECTS COAX CONNECTOR. It does not function on open wire or balanced connections.' How can this be accurate when you look at the schematic? It looks to me like the balun is still a factor whether or not the bypass is engaged, however, the capacitors and inductor are bypassed when using balanced line with the bypass engaged.
Dentron MT-2000A Schematic
The connection from S1A left to the so239 should have the line going to the center of the connector I believe.
Dentron Tuner Manual
Also, it looks like the balun could be bypassed using balanced line if one side of the balanced line was connected to the Single Wire connector while the other side of the balanced line was jumpered (using a wire with alligator clips) to the chassis.
