Yaesu ATAS-120A Motorized Mobile Antenna: 40m through 70cm
The ATAS-120A is a unique mobile antenna designed for use with Yaesu transceivers equipped with the proper controller, such as the FT-991(A), FT-897D, FT-847, FT-857D, and FT-100/100D. The ATAS-120A uses a motorized tuning system which resonates the radiating element for the lowest SWR without the need for expensive inconvenient monoband whip assemblies.
The ATAS-120A is designed to mount directly onto a standard mobile antenna mount with a SO-239 connector (not included).
**Not recommended for use with a magnet mount**
For use with the 144 and 440 MHz bands, you may need to purchase a duplexer (FT-897/857/FT-100) or a triplexer (FT-847) to properly connect the antenna to the appropriate antenna jacks on the radio.
