The VHF/UHF or VHF Blade Antenna attaches to the radio via which connector?

• A. SMA connector
• B. Threaded N-Connector (TCN)
• C. BNC connector
• D. DIN connector

Answer: (B)

The key idea here is using a rugged, reliable RF connector that can handle field conditions without coming loose. For a VHF/UHF blade antenna, the threaded N-type connector provides a sturdy, weatherproof coupling that resists vibration and accidental disconnection, which is essential when you’re moving, sweating, or wearing gloves. It also supports the 50-ohm impedance, good power handling, and broad frequency range typical of VHF/UHF gear, ensuring a clean, low-reflection connection. That combination makes the threaded N-type connector the standard choice for attaching blade antennas to radios. Smaller or bayonet-style connectors (like SMA, BNC, or older DIN types) don’t offer the same balance of durability, secure engagement, and power tolerance needed for field use.
