The Antenna Tuning Unit R&S® FK2900M is a member of the HF TransceiverFamily R&S® XK2000. The R&S® FK2900M matches the R&S® XK2500 and R&S® XK2900 transceivers to rod and wire antennas. It is designed for stationary or shipboard applications. It can handle power up to 1000 W CW and PEP at a 100 % duty cycle. The R&S® FK2900M operates in the frequency range from 1.5 MHz to 30 MHz where it performs an antenna impedance transformation into 50 Ω in both the receive and transmit mode. Additionally, it provides preselection in the receive mode.

Owing to the silent tuning feature of the Transceiver R&S® XK2900L, low probability of intercept (LPI) is enhanced.

Design

The rugged, waterproof and dustproof construction of the R&S® FK2900M allowsits use in stationary, landmobile and shipboard applications, even in harsh environments and continuous 24- hour operation.

BITE

The antenna tuner is included in the continuous monitoring of the system BITE so that status reports are displayed at the control unit of the transceiver system.

All boards have ECM filters. For protection against overvoltage as produced by lightning strokes to the antenna, the R&S® FK2900M output is provided with lightning protection.
