Air-core coils and high-quality ceramic capacitors
•
Air-core coils (no magnetic materials) and high-quality NP0 (C0G) ceramic capacitors usage throughout
the matching circuit.
Harmonic suppression
•
Improves harmonic suppression - the matching network is a low-pass L filter.
Saves space on the operating position
•
ACOM 04AT can be located up to 100 m (330 ft) away from the shack.
Remote installation
•
Allows remote installation, including outdoors, close to the antenna feed point, minimizing losses.
Integrated antenna switch
•
Integrated four-way antenna switch - less coaxial cable, shorter unmatched sections, less losses.
Automatically and manually antenna switching
•
Antennas can be automatically and manually switched from the amplifier front panel. The last used
antenna selection is memorized.
Customized antennas names and types
•
Indication and editing of names and types of antennas in editable freeform.
Protection mechanisms
•
Various protection mechanisms, including: antenna overvoltage, antenna overcurrent, excessive power
during operation and tuning, extreme temperatures and power supply voltages, as well as relay hot-
switching.
Safe power supply
•
Safe power supply voltage (26 VDC).
BYPASS mode
•
BYPASS mode - all components of the matching network are excluded, allowing direct operation of
broadband antennas.
SERVICE menu
•
This menu allowing analysis of the tuner status and review of the used resource of coils and capacitors
for all memorized and current tuning presets.
Lightning arrestor and bleeder resistor
•
Integrated lightning arrestor and bleeder resistor for protection against static discharges; automatic
grounding of antennas on powering down.
