Open Box Yaesu ATAS-120, Motorized Mobile Antenna

Motorized Mobile Antenna: 40m through 70cm

The ATAS-120A is a unique mobile antenna designed for use with Yaesu transcivers equipped with the proper controller, such as the 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 an 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. 

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.

For base operation (i.e. balcony), VHF/UHF performance can be enhanced by the installation of the optional ATBK-100 Antenna Base Kit.
