280. In a marine RADAR set, a high VSWR is indicated at the magnetron output. The waveguide and rotary joint appear to be functioning properly. What component may be malfunctioning?
A high VSWR at the magnetron output, with a functioning waveguide and rotary joint, indicates a problem with the waveguide array termination. This component creates an impedance mismatch, causing reflections and a high VSWR.
