Description

  • ACOM ATU 04AT-AUTOMATIC REMOTE TUNER-for 700S- 1200S -2020S

  • Remote matching of antennas – fewer losses in the feed line. Designed for installation in a shack, under a shed, or in open (see mounting kit options). Can be distanced up to 100 m (330 feet) from the amplifier.
  • Powered and controlled directly from the ACOM solid state HF+6m amplifiers through the amplifier RF output cable only – there is no need for power or control cables between the shack and the tuner.
  • Provides automatic or manual antenna change and automatic antenna impedance matching to the ACOM solid state HF + 6m amplifiers, controlled entirely from the amplifier front panel and your transceiver CAT. or via your remote PC.
  • Guards the transceiver and amplifier against excessive impedance mismatch during the tuning process.
  • Operates with two types of tunings: full tuning (basic matching cycle) and fast tuning (retrieving user tuning patterns from nonvolatile memory.
  • Full tuning is 100% automated however a cycle is initiated only by the operator. User tunings track the antenna and frequency changes automatically during amplifier and transceiver operation.
  • Four typical antenna types: Regular, Sharp, Wide, and Fixed-frequency are available so the operator can adapt the frequency segment width to the specific antenna bandwidth; BYPASS mode is also available.
  • Antennas appear with a number, type, and user-editable name on the ACOM solid state amplifiers screen.
  • Tuning availability is presented by a graphic scale on the ACOM solid state amplifiers screen.
  • Plenty of antennae- and tuner-related information is available on the ACOM solid state amplifier screen: menus ATU SERVICE, ATU MEASURE, ATU TUNINGS LOOKUP/ERASE, Resource-estimate function, etc.
  • Tuning “age” warning can be set to warn you when you attempt to use an outdated tuning. to retune is a simple one-touch function.
  • The user can archive all tunings from nonvolatile memory in a computer file as well as upload earlier archived files in the ACOM 04AT nonvolatile memory through the ACOM solid state amplifier’s RS232 port.
  • Protections: PS voltage, Reverse PS polarity, Excessive RF voltage, RF current or reflected power at the antenna outputs, Excessive tuning power, Excessive Input power, Hot switching of relays, Overheating, etc.
  • Protected against the building up of static electricity in the antennas via bleeding resistors and against close lightning strikes via gas-filled discharger; unused antennas are directly grounded during operation as well as all antennas are grounded when the ACOM 04AT is powered off.
