9-32C5 D
 Interference induced from nearby HF transmitters may cause Inmarsat system failures. What is the most appropriate action to resolve this problem?
A. Install a longer ground lead to the INMARSAT terminal. 
B. Install a low-pass filter between the coax cable and antenna.
C. Reduce bias to the INMARSAT antenna's Low Noise Amplifier.
D. Install ferrite clamps on the coax cable to suppress induced RF.
