It covers 470\u2013960 MHz with a directional 60\u00b0 optimal pickup angle and linear polarization to focus reception where you need it. An integrated amplifier provides \u20139 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.<\/p>\n

Connection and power are straightforward via a 50 \u03a9 BNC feed; when your receiver or antenna distributor supplies 12\u201316.8 V DC bias, the SF1 runs in active mode (approx. 12 V\/90 mA). A clear gain display with +\/\u2013 buttons simplifies on-site adjustment, and a mounting base with 3\/8″-to-5\/8″ threading supports common stands. Key RF performance figures include OIP3 39 dBm and max RF input 30 mW, helping maintain signal integrity in complex RF environments.<\/p>\n

For best results, aim the antenna toward the coverage area, maintain line-of-sight, keep it \u22651 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 \u00d7 328.8 mm, 532 g, operating \u201310 \u00b0C to +55 \u00b0C. Ideal for multi-receiver carts and distributed systems on corporate\/commercial sets where clean, coordinated RF is critical.<\/p>\n","protected":false},"excerpt":{"rendered":"
