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.
| RF power input | 1000 W, PEP or average |
| Duty cycle | All modes including data operation, within constraints of internal temperature (see temperature spec) |
| Frequency range | 2 MHz to 30 MHz |
| Tuning range versus antenna type | 5 metre whip: 3 MHz to 30 MHz 10 metre whip: 2.5 MHz to 30 MHz 25 to 50 metre long wires: 1.6 MHz to 30 MHz |
| Duty cycle | 100% at 500 W PEP Voice 100% at 500 W ARQ 100% at 500 W FEC |
Note: Effective tuning requires the installation of an efficient grounding system in conjunction with the antenna
| RF tune power required | 10 W |
| Tune time | 3 to 5 S, first tune typical < 20 mS, memory tune |
| Input impedance | 50 ohm |
| Input power requirements | 28 V DC, 4 A peak, 1.8 A average |
| Tuning accuracy | 1.5:1 VSWR typical |
| Memory channels | 100 |
| Temperature (operating) | -30° to +55°C (ambient inside case) |
Note: This temperature can easily be exceeded if the case is exposed to direct sunlight. For FSK operation, it is important that the tuner is installed so that the case is not exposed to direct sunlight
| Shock, vibration | MIL-STD 810G (with shock mount) |
| Immersion | Waterproof; immersion to 1 metre |
| Humidity, fungus, sand & dust, salt, fog | MIL-STD 810G |
| Controls and indicators | |
| Connectors | RF input, control input, RF output, grounding lug |
| Control interface | Specific to Barrett Communications series of HF transceivers |
Specifications are typical. Equipment descriptions and specifications are subject to change without notice or obligation.
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.
