DEITY BF1 Butterfly Antenna — Passive Omnidirectional Antenna (Pair)

The DEITY BF1 Butterfly Antenna is a lightweight, ultra-wideband passive antenna set designed for professional wireless microphone systems. Offered as an antenna pair with mounting arms and BNC cabling, the BF1 delivers broad UHF coverage and rugged, weather-resistant construction for location sound, film and broadcast workflows.

Engineered for versatility, the BF1 covers 470 MHz–1 GHz (Global OneBand™ coverage) with a compact “butterfly” footprint that fits on sound bags, racks and camera rigs. The antennas are weather-sealed to IP65 and mount via a 1/4"-20 threaded metal mount for secure placement on arms, stands or rigs.

Designed for location mixers and rental houses, the BF1 set provides a bag-friendly antenna solution that ships with the practical mounting and cabling needed to integrate into wireless RF chains.
