R&S®FK2100/FK2100M Antenna Tuning Units (ATU)
For automatic matching of all commonly used antennas
The Antenna Tuning Unit R&S® FK2100 belongs to the R&S® XK2000 equipmentfamily. It automatically matches antennas, in particularvery short antennas, to the 150 W HF Transceiver R&S® XK2100. The sturdyand water- proof plastic casing of R&S® FK2100 is shock- and UV-resistantand thus ideally suited for mobile applications. The R&S® FK2100M, which is a seawater- and drop-resistant versionof the R&S® FK2100, is especially designed for shipboard applications and can match antennas with very low ohmic resistance.
Particular attention was paid to obtaining effective lightning protection. Both ATUs are fully arc-protected against direct lightning strokes. They are tested to withstand arcs of 10 kV/10 kA. An automaticBIT (built-in-test) is provided for fault detectionand reporting to the R&S® XK2100 transceiver.
