This is an essential, high-quality adapter for scanner and ham radio enthusiasts. It allows you to connect a handheld radio, scanner, or piece of test equipment that uses a BNC port to a standard mobile or base station antenna.
It converts the BNC-Male (twist-lock with pin) plug into a heavy-duty SO-239 (UHF-Female) socket. This allows you to use any standard PL-259 coax cable, giving you a massive boost in receive and transmit range over a stock antenna.
💡 Please Note: Sold as a Single Adapter
The main product image shows two adapters from different angles so you can see both connectors. This item is sold as a single (1) adapter.

✅ Will This Fit My Device?
This adapter fits any device with a BNC-Female port (the twist-lock connector with a center hole).
This adapter is a perfect fit for:
- Most Uniden, Whistler, and GRE handheld scanners

⚠️ Check Your Connectors
This adapter does NOT fit most handheld ham radios from Baofeng, Yaesu, Quansheng, or Retevis, as they use SMA-style connectors.
