Yaesu's patented ATAS™ (Active Tuning Antenna System) provides 7/14/21/28/50/144/430 MHz bands coverage with automatic motorised tuning on the Yaesu FT-100/100D/817/847/857/FT-897 transceivers.
Using control signals from the transceiver's microprocessor received via the coaxial cable, the ATAS internal motor adjusts the radiator length for the best SWR.
