What does an A-395 Relay Assembly provide?

• A. Provides relay action to deselect ADF antennas when radios are keyed.
• B. Powers the ADF transmitter
• C. Controls the ADF sensitivity
• D. Switches from the ADF antenna to the Comms antenna

Answer: (A)

When you transmit, the ADF receiver should be isolated from the transmitter to avoid interference. The A-395 Relay Assembly provides exactly that—a switching action that deselects the ADF antennas whenever the radios are keyed. In practical terms, it automatically disconnects or shifts the ADF antenna path so the transmitter’s energy doesn’t affect the ADF receiver, then returns the ADF antennas to normal operation when transmission ends. This device isn’t responsible for powering the ADF transmitter, nor for adjusting how sensitive the ADF is, and it doesn’t function as the switch between ADF and Comms antennas. Its specific role is to ensure the ADF path is deselected during transmission to maintain proper operation and reduce interference.
