Yaesu's patented ATAS™ Active Tuning Antenna System has been enhanced with the latest model: ATAS-120A. This is a unique mobile antenna that provides HF, VHF and UHF coverage with automatic motorized tuning.

Designed for use with Yaesu transceivers that support ATAS, microprocessor control signals are sent on the coaxial cable to adjust the antenna radiator length for best SWR.

Yaesu ATAS-120a active tuning antennas cover the 7, 14, 21, 28, 50, 144 and 430 MHz Amateur bands and are compatible with the Yaesu FT-857D, FT-897D, FT891, FT-991, FT-991A and the FT-450D.

They are typically attached to a vehicle hatch or trunk lip UHF mount (not supplied), also available from DX Engineering. They can be adapted to portable operation with the appropriate mount and counterpoise.

Specifications of the Yaesu ATAS-120A Auto Active Tuning Antennas:

* Operational Bands: 40, 20, 15, 10, 6 and 2 meters and 70 cm
* Height, approx.: 4.59 to 5.25 ft.
* Weight, approx.: 1.98 lbs.
* Input Impedance: 50 ohms
* Maximum Power: 120 Watts, SSB, CW, 50% duty cycle
* Matched SWR: Less than 2.0:1 with proper grounding or counterpoise

As with any HF, VHF and UHF mobile antenna system, performance of this antenna system depends upon the grounding of the mount and bonding to the metal vehicle surfaces to create an optimal ground plane.

Portable VHF and UHF operation is made possible with the addition of the optional Yaesu ATBK-100 Antenna Base Kit. This kit is not required, nor should it be used, for mobile operation.

Operational convenience and performance is available for your Yaesu HF, VHF and UHF Mobile Transceiver. Order Yaesu ATAS-120A Active Tuning Antennas from DX Engineering.

After using an ATAS 100 for many years, it finally gave up the ghost so went with the ATAS 120. Every bit as good as the ATAS 120. So easy to use with the Yeasu FT-891
