Key facts

  • High RF power at small antennas
  • High efficiency (no resistive loading)
  • HF-cable-only interface
  • Cosite robust, fast tuning
  • Transceiver-independent control interface and power supply (via R&S®GX002)

For 1 kW transmit power

The R&S®FK002H0 is a standalone antenna tuning unit (ATU). It can match the impedance of a radiator to 50 Ω for every frequency between 1.5 MHz and 30 MHz.
The R&S®FK002H0 is powered and controlled by the R&S®GX002 junction unit.
The R&S®FK002H0 can be operated under harsh environmental conditions with continuous 24-hour operation. The rugged, waterproof and dustproof R&S®FK002H0 construction can be used in stationary, land-mobile and shipboard applications.

Features & benefits

High RF power at small antennas

The fully automatic antenna tuning unit perfectly matches antennas (e.g. rod antennas taller than 7 m) to the transmitting system for full RF output power capabilities of up to 1 kW.

High efficiency (no resistive loading)

The R&S®FK002H0 provides highest efficiency. It does not use resistive loading to match radiator impedance to 50 Ω.

HF-cable-only interface

The R&S®FK002H0 requires just one HF cable for operation. Power supply as well as control signals are all handled via the R&S®GX002 junction unit by the RF cable.

Cosite robust, fast tuning

The R&S®FK002H0 features different tuning modes. In active tune mode an ATU measures the antenna impedance and the correct tuning element setting is found though iteration.
In silent tune mode, the ATU reads a tuning element setting that was previously found and stored during the learning process from memory and sets it accordingly.

TX-independent control interface and power supply

The R&S®GX002 junction unit handles all communications to and from the transceiver. Thanks to universal transceiver control interfaces such as LAN, coaxial and optical ports, the junction unit as well as the R&S®FK002H0 can work with the latest shortwave transceivers, with older Rohde & Schwarz transceivers in legacy applications and with transceivers from other manufacturers.
