mAT-50 outdoor automatic antenna tuner

Similar to the mAT-40 but instead of using a dedicated control cable from the radio to the outdoor tuner it utilizes an in-shack control head for either Icom, Kenwood, or Yaesu transceivers.  Control power to the outdoor unit to actuate the tuner is sent from the control head to the unit via the coaxial cable, allowing any length of run between the radio and antenna.  Can also be used manually with any of the Icom, Kenwood, or Yaesu control heads for any transceiver to send tune signal to the remote unit if an external tuner interface jack is not on the radio. 

mAT-K100 tuner for Icom & Kenwood

The mAT-K100 is an automatic antenna tuner specially designed for modern Kenwood and ICOM HF transceivers. It has two control cables to choose from: mAT-CI (Icom) and mAT-CK (Kenwood).  mAT-CK for Kenwood is included standard with the tuner. mAT-CI is sold as an option.

The mAT-K100 provides automatic antenna tuning across the entire HF spectrum plus 6 meters at power levels up to 120 watts. It will tune dipoles, verticals, yagis, long wire, or virtually any other coax-fed antenna. Matching range of 5-1500 ohms far exceeds the capability of the internal automatic antenna tuner.  120 watts power handling capability.

Machined, black oxidized aluminum case.

mAT-125E General automatic antenna tuner

The mAT-125E is a general use external automatic antenna tuner for use with any HF transceiver.  Automatic RF-sensed or manual tuning modes.  Automatic RF-sensing and battery power means no control cable needs to be connected to the tuner.  Add a 50 ohm coax cable, start using the unit with virtually any HF transceiver.

1.8-54 MHz continuous coverage, 16,000 frequency memories, can be used QRP as the tuner requires only as little as 100 mW to actuate.

Two 18650 lithium batteries installed inside tuner to provide power for the tuner.  mAT-125E uses little power while tuning and essentially zero power when in standby, meaning the unit can be run for a very long time off of a single battery charge whether in use at home or the field.  Rechargeable batteries and USB charging cable included with tuner.

Machined, black oxidized aluminum case.

mAT-1500Pro 1500 watt autotuner - NEW!

mAT-1500Pro is mAT-TUNER's new 1500 watt automatic antenna tuner.  Integrated autotuner interface allows the tuner to be controlled from the front panel TUNE button of many Icom, Kenwood, and Yaesu HF transceivers. (Accessory cable sold separately).  The integrated interface also makes use of the autotuner error-proof as the correct transmit power is sent to the tuner by the radio and the amplifier keying relay is disabled, preventing the amp from accidentally being keyed while in the tune sequence.  Tuner can also be used with any HF transceiver by manually setting power output from radio and using no transceiver interface cable.  2 antenna output connectors with front panel antenna switch.
