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.
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.
The ATAS-120A is designed to mount directly onto a standard mobile antenna mount with a SO-239 connector (mount not included).
- Don’t use a magnet mount: even if it can support the wind load, it’s not going to give the motor a sufficient path to ground.
- Whatever mount you use select should be well grounded so the drive motor can operate properly. With the Comet CP-5M, this means insuring the set screws are touching bare metal, not paint.
