    • The invention relates to a diesel-electric drive system comprising a permanently excited synchronous generator (4), which is mechanically coupled to a diesel motor (2) on the rotor side and has an electrical connection to a voltage link converter (6) on the stator side, said converter having a respective self-commutated pulse-controlled converter (12, 14) on the generator and load sides. The converters are interconnected on the d.c. voltage side by means of a d.c. link (18). The system also comprises a braking resistor (20), which can be electrically connected to said d.c. link (18). According to the invention, a multi-phase braking resistor assembly, which can be electrically connected in series to the multi-phase stator winding system (74) of the permanently excited synchronous generator (4) by means of a multi-phase actuator (32), is provided as the braking resistance. This permits the provision of a diesel-electric drive system which no longer requires an additional brake attenuator and in which the mode can be changed between generator mode and operating mode, the speed of said diesel motor being freely set in the operating mode.

    • According to various exemplary embodiments, an antenna assembly generally includes one or more antennas, such as a single multi-frequency antenna, first and second stacked patch antennas, etc. The antenna assembly may be operable for receiving signals having different frequencies (e.g., a frequency associated with a satellite digital audio radio service (SDARS), a frequency associated with a global positioning system (GPS), etc.). The antenna assembly may generally include at least one antenna (e.g., a single multi-frequency antenna, first and second stacked patch antennas, etc.) having at least one feed point and tuned to at least one of a first frequency and a second frequency that is different than the first frequency. A low noise amplifier may be in communication with the at least one feed point for amplifying signals having the first frequency and signals having the second received from a signal output. A single communication link may be used for communicating an output signal of the antenna assembly.
