Housed in a fully weatherproof enclosure, the Barrett 1kW Automatic Tuning Unit (ATU) (BC407508) will tune long wire antennas effectively up to a length of 10 metres and wire loop antennas or whip antennas over a frequency range of 2 to 30 MHz and is suitable for both marine and land applications.
Tuning is rapid, typically 10 seconds the fi rst time RF is applied, either whilst the operator is talking or when the “Tune” control is activated on the transceiver.
The 1kW ATU features a memory facility that stores the configuration required to tune to a frequency. On any subsequent use of that frequency, the 1kW ATU reconfigures to the stored settings in, typically, less than 150 milliseconds. Following initial tuning, the antenna’s VSWR is monitored. If any significant variation occurs, the 1kW ATU will re-tune the antenna automatically.
This unit is typically paired with the Barrett 4075 High Power HF Transmitter system. BCA407535 4075 1KW ATU Shock/Vibration plate for Marine/
Mobile installation sold separately.
