Which of these connector types is commonly used for low frequency or dc signal connections to a transceiver?
The correct answer is C: RCA Phono. The connector type commonly used for low frequency or DC signal connections to a transceiver is RCA Phono. RCA connectors are commonly used for audio and low-frequency signals. For amateur radio operators, this is standard for audio connections. Understanding this helps when connecting audio equipment.
Exam Tip
Low frequency/DC connector = RCA Phono. Think 'R'CA 'P'hono = 'R'adio 'C'onnector 'A'udio. RCA connectors commonly used for audio and low-frequency signals. Not PL-259 (RF), not BNC (RF), not Type N (RF) - just RCA Phono.

Real-World Application
You connect audio from your computer to your transceiver. You use RCA Phono connectors - they're standard for audio and low-frequency connections. RCA connectors are commonly used for audio, while PL-259, BNC, and Type N are for RF connections.
Key Concepts
Why Other Options Are Wrong
Option A (PL-259): Incorrect. PL-259 is for RF connections (UHF connector), not low frequency or DC. PL-259 is for RF, not audio.
Option B (BNC): Incorrect. BNC is for RF connections, not low frequency or DC. BNC is for RF up to 4 GHz, not audio.
Option D (Type N): Incorrect. Type N is for RF connections, not low frequency or DC. Type N is for RF up to 10 GHz, not audio.
