Explain the basic steps to perform an antenna system check in the field.

• A. Only test SWR
• B. Inspect connectors and cable, verify radio power, measure SWR, confirm antenna attachment, and ensure proper stowage.
• C. Only verify power
• D. Only inspect connectors

Answer: (B)

A comprehensive field antenna system check must address both mechanical integrity and RF performance. You inspect connectors and cable for wear, looseness, or damage that could cause reflections or intermittent loss. You verify the radio power is present and the unit can transmit at the expected level, ensuring the power path is healthy. You measure SWR to confirm the antenna presents the correct impedance and to catch any mismatches that would waste power or stress the transmitter. You also confirm the antenna is securely attached to its mounting and that the system is stowed properly to prevent movement, snagging, or damage in the field. This multi-faceted approach ensures all parts of the RF path and installation are ready, not just one aspect. A single focus, like SWR or power or connectors alone, could miss a fault that stops the system from working when you need it.
