Description

  • ACOM 03AT | Automatic HF Antenna Tuner

  • Usage
    The Automatic HF Antenna Tuner (AATU) model ACOM 03AT is a complete and self-contained device for automatic matching of HF symmetrical antenna impedance to an unbalanced 50 Ohm output, that covers a continuous 1.8 to 16 MHz frequency range and will withstand 200 to 2500 W input power depending on the antenna SWR. ACOM 03AT consists of two modules – A Remote Tuner Unit and Remote Control Unit (RCU).

    Easy to operate
    The only operator obligation is to apply CW power while the matching process is fully automatic.

    Remote matching
    Remote matching – fewer losses in the feed line. The remote tuner unit design complies with outdoor installation requirements. This permits you to locate it close to the antenna feed points, thus considerably reducing the high-SWR RF path length.

    Automatic operation
    Operating automatically with any transceiver without special signals – 10 to 100 W CW for several seconds is the only requirement to perform automatic impedance matching.

    Optical control link
    Optical control link (up to 50 m) between RCU and remote tuner unit. This avoids erratic control at a strong electromagnetic RF field which is the typical case in the near-field zone of an antenna when emitting 1-2 kW.

    BYPASS function
    Features BYPASS function, performed by default also when powered off, where the effect of the inductors and capacitors on the impedance is excluded for broadband operation (the balun transformer is still inline).

    Resource-estimate function
    Resource-estimate function (STATUS) gives the percentage of inductors and capacitors involved to achieve a match. This offers a possibility for monitoring the condition of the RF path and the antenna, thus forewarning possible problems.

    Protection against atmospheric electricity
    Protected against atmospheric electricity via sphere spark gaps and a bleeder choke.

    Protection
    Guards your transmitter during the tuning process against excessive impedance mismatch by inserting a powerful attenuator at the input, and removing it after that. Protected against relay “hot” switching, excessive antenna voltage, overheating, etc.

    Non-volatile memory
    Non-volatile memory for 99 different user’s tuning settings and selection of the power-on default.

    Option

    • Unbalanced output with 50 Ohm UHF(SO-239A) connector.
