MAT-30 Automatic Antenna Tuner For Ham Radio


The mAT-30 connects to the radio via its CAT / LINEAR jack to control the tuning cycle; the transceivers Tune button controls the tuner. The CAT / LINEAR jack also powers the tuner, so it requires no external power supply. The mAT-30 is specially engineered to integrate with your Yaesu FT-100 / 857 / 897 / 450D / 891 HF radio.

The mAT-30 is an automatic tuner intended for use with modern Yaesu transceivers. It works with some Yaesu transceiver that supports an FC-30, FC-40 or FC-50 Yaesu tuner; a partial list of compatible units includes FT-100, FT-857, FT-897, FT-450D, FT-891. The interface cable is included. The operating is the same as the method of the Yaesu tuner, which is simple and convenient. The mAT-30 can work within the range of 3 MHz to 54 MHz.

The mAT-30 is specially engineered to integrate with your Yaesu FT-100 / 857 / 897 / 450D /891 HF radio. The mAT-30 connects to the CAT (Computer Automated Transceiver) port on the back of the radio. The CAT interface allows an external device such as a PC or the mAT-30 to control the FT-100 / 857 / 897 / 450D / 891 by sending it serial commands. The mAT-30 takes advantage of this interface to simplify the tuning process – one button push is all that is needed in order to switch the radio to FM mode, reduce output power, transmit a carrier, measure the transmit frequency, and then restore the radio to its previous mode and power level!

The mAT-30 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, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedance, far greater than some other tuners you may have considered, including the built-in tuners on many radios.

The mAT-30 also features advanced memory tuning, providing 16000 memory locations; when tuning near a previously used frequency it will recall the settings for nearly instant tuning. It learns your favourite frequencies and bands as you use it. You can also start a tuning cycle manually whenever necessary.
