Yaesu's patented ATAS™ (Active Tuning Antenna System) makes the ATAS-120A a unique mobile antenna designed for use with Yaesu's transceivers, such as the FT-897, FT-857, FT-847, FT-100/100D and the FT-450.

It provides 7/14/21/28/50 Mhz bands coverage with automatic motorised tuning

Note: The ATAS-120A is designed specifically for use with Yaesu transceivers equipped for the "ATAS" system, and is NOT capable of automatic operation with other transceiver models.
