The Barrett 1 kW ATU automatically matches the 50 ohm output of the 2075 high power transmitters to a wide variety of end-fed unbalanced antennas such as whips and long wires.
The Barrett 1 kW ATU has a 100-channel memory that allows “silent tuning” on channels previously tuned in less than 20 mS. The tuner can provide tactical security by permitting remote location of the antenna tuner and antenna up to 30 metres from the associated transmitter.
2075 1 kW automatic antenna tuner is fully waterproof and can be immersed to 1 m.
An opto-coupled interface is supplied to provide high RF interference immunity on long control cable runs.
The 1 kW automatic antenna tuner operates from 1.6 to 30 MHz.
Typically 3 to 5 seconds on initial tune and less than 20 mS on memory tunes.
The memory tune system is fully compatible when operating ALE to MIL-STD 188-141B.
Operates at 1000 Watts PEP or average at 100% duty cycle.
