Interference induced from nearby HF transmitters may cause Inmarsat system failures. What is the most appropriate action to resolve this problem?
-
Install a longer ground lead to the INMARSAT terminal.
-
Install a low-pass filter between the coax cable and antenna.
-
Reduce bias to the INMARSAT antenna's Low Noise Amplifier.
-
Correct Answer
Install ferrite clamps on the coax cable to suppress induced RF.
