Product Overview

The mAT-8101 is an automatic antenna tuner designed exclusively for the Icom IC-F8101 transmitter. It cannot be used with any other Icom transmitters.

The tuner connects to the transmitter using the supplied mAT-232 adapter cable (RS-232). The transmitter supplies power to the tuner through this cable, communicates with it and controls the operation of the tuner. The tuner does not require additional power supply.

It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. It can match a wide range of coax-fed antennas and impedances.

The mAT-8101 connects to the transmitter via its RS-232 Adapter cable (mAT-232) to control the tuning cycle. The Adapter cable also powers the tuner, so it requires no external power supply.
