Compatibility and performance

Connects directly to handheld radios with a compatible BNC antenna connection. SMA-equipped radios require the correct BNC adapter, sold separately unless included in your selected package.

The SWR specification applies at the center frequency. Actual SWR varies across the operating band and with the radio, adapter, and surrounding conditions. For UHF business channels, choose the Business & Itinerant version or request custom tuning.
