Matching transmitting/receiving systems of the R&S® Series 2000 radio family to shortwave broadband antennas

Key Facts
Picture R&S®FK859C1 Line Flattener

The R&S®FK859C1 line flattener with an input VSWR of ≤1.3 can be used for matching transmitting/receiving systems to shortwave broadband antennas (e.g. log-periodic antennas, cage antennas, broadband dipoles).

Matching is achieved with microprocessor control by switching binary-stepped line sections and series capacitors into circuit.

The tuning information for 100 channels can be stored in a nonvolatile memory. The R&S®FK859C1 is accommodated in a 19" rackmount of three height units. Cooling is provided by a blower.
