🔍 Key Concepts

• Full-duplex VHF operation uses one frequency to transmit and a different frequency to receive at the same time. • To prevent receiver overload and interference, you need good isolation between the transmitting and receiving paths. • Antenna physical separation and placement are key ways to increase isolation on a vessel.

💭 Think About

• In full-duplex, which two parts of the system must NOT interfere with each other for clear simultaneous transmit and receive? • Which pair of antennas, if placed too close together, would most directly cause the receiver to be swamped or desensitized by the transmitter? • Look at each option and ask: does this separation actually improve isolation between the active transmitter and the sensitive receiver during full-duplex operation?

✅ Before You Answer

• Identify which option specifically refers to separation between a transmitting antenna and a receiving antenna used at the same time. • Confirm which antennas in the system are most critical to keep apart to avoid receiver desensitization and feedback. • Before choosing, rule out options that only talk about separation between devices that are both transmitters or are not the main transmit/receive pair in full-duplex.
