User manual YAESU ATAS-120A

[. . . ] ACTIVE TUNING ANTENNA SYSTEM ATAS-120A INSTALLATION/OPERATING INSTRUCTIONS The is a unique mobile antenna designed for use with Yaesu the transceivers equipped for the ATAS system, such as the FT-897, FT-847, FT-857 and FT-100/-100D. The utilizes a motorized tuning system which resonates the radiating is element for lowest SWR without the need for expensive, inconvenient monoband resonating whip assemblies. [. . . ] Note: Installation of the on a hatchback or trunk lid may not permit a low SWR to be obtained. A solid bond to the car body is important so as to establish a counterpoise for the vertical radiating element. Connect the coaxial cable from the mounting base to the transceiver's HF antenna jack. Refer to the transceiver's operating manual, and set the transceiver's Menu selections associated with the ATAS system. For operation on the 144 and 430 MHz bands, in addition to HF/50 MHz, you may wish to consider the purchase of a "Duplexer" (for the FT-857, FT-897 and FT-100/-100D) or "Triplexer" (for the FT-847) device to connect to the appropriate transceiver's antenna jacks; the Duplexer or Triplexer will then automatically pass RF power from the band in use while isolating the other two antenna jacks. If you do not have a Diplexer or Triplexer, the coaxial cable connector from the will have to be moved manually to the appropriate antenna jack when you wish to operate on VHF or UHF. CAUTIONS For mounting onto a trunk lid or hatchback of a vehicle, utilize a mount which provides secure, strong mechanical contact to the vehicle's frame (to support the antenna's cross-sectional area while driving, as well as for grounding purposes). Suitable mounts include the Diamond models TE5M and K400. In the interest of operator safety, always use the minimum transmitter power necessary to establish and maintain communications while operating mobile, and restrict transmitter operation when pedestrians are within one meter (3. 3 feet) of the radiating element. Do not allow anyone to touch the radiating element during a transmitting session, due to the danger of burning of the skin caused by the high RF voltage present. in a position where the Do not install the radiating element could come in contact with (A) any electrical wiring, which could cause lethal shock, or (B) a grounded metal surface, as this will disrupt communications and may cause arcing. Do not touch the Antenna Coil Assembly of the , so as to avoid undue stress to it or the mechanical components within it. Do not attempt to perform the tuning process while driving a vehicle.
