Description
The SF1 Active Directional (sharkfin) Antenna is a broadband UHF receive antenna designed to improve range and reliability for professional wireless systems. It covers 470-960 MHz with a directional 60° optimal pickup angle and linear polarization to focus reception where you need it. An integrated amplifier provides -9 dB to +21 dB gain in 1 dB steps (with overload indication), while unpowered operation delivers typical 6 dBi passive gain for flexible deployment. The enclosure is IP54-rated for splash and dust resistance, suitable for location film and theatrical use.
Connection and power are straightforward via a 50 Ω BNC feed; when your receiver or antenna distributor supplies 12-16.8 V DC bias, the SF1 runs in active mode (approx. 12 V/90 mA). A clear gain display with +/- buttons simplifies on-site adjustment, and a mounting base with 3/8"-to-5/8" threading supports common stands.
For best results, aim the antenna toward the coverage area, maintain line-of-sight, keep it ≥1 m from other antennas, and avoid nearby metal. Use the active gain only to compensate coaxial cable loss (see typical attenuation guidance) to prevent receiver overload; the red indicator alerts you to excessive input. Physical details: 376.5 × 328.8 mm, 532 g, operating -10 °C to +55 °C. Ideal for multi-receiver carts and distributed systems on corporate/commercial sets where clean, coordinated RF is critical.
