Yaesu ATAS 120A
Covers 7 amateur bands ! (7/14/21/28/50/145/433MHz)
The ATAS120A is a unique mobile antenna designed for use with Yaesu transceivers equipped for the ATAS, such as the FT847, FT857,FT897, and the older FT100 range.The ATAS120A uses a motorised tuning system which resonates the radiating element for lowest SWR .
The ATAS-120A utilises a motorised tuning system which resonates the radiating element for lowest SWR without the need for expensive, inconvenient monoband resonating whip assemblies.
This amazing antenna is designed to mount directly onto a standard mobile antenna mount (not supplied) which is compatible with its Type M (SO-239) base connector.
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.
Comes with a waterproof cap for ease of mind in our British weather...
