CU-9150 1 KILOWATT AUTOMATIC ANTENNA COUPLER

The Sunair CU-9150 is a proven solution in communications applications where rugged, reliable, flexible, and adaptable equipment is required.
The next-generation antenna coupler has the ability to tune a wide variety of antennas over the entire HF band.

The CU-9150 operates continuous duty at power levels up to 1kW Average / 1 kW PEP over 2 – 30 MHz and 500W Average / 1 kW PEP over 500W over 1.5 – 2 MHz.

The antenna coupler uses a high speed digitally-tuned network to support whips and long wire antennas, while a built-in microprocessor controls internal
selectable RF circuit elements to provide 50 Ω coaxial feed line impedance, with a maximum 1.5:1 VSWR.

Typical tuning time is less than 4 seconds at any new frequency across 1.5 – 30 MHz, and 30 ms from memory.
The Sunair CU-9150 is built to meet harsh environmental requirements of exposed dust and saltwater installations, such as transportable shelters, rooftop, and shipboard.

Designed as a companion to the Sunair 9000D series radios and LPA series amplifiers, the product can also be interfaced to other manufacturers’ available HF products.

The antenna coupler’s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense.

More than a thousand are in daily service as integral components of critical strategic communications solutions worldwide.
