{"product_id":"sf1-directional-antenna","title":"Deity SF1 Directional Antenna, Microphone Accessory","description":"\u003cp\u003e\u003cspan\u003eThe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eConnection 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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFor 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.\u003c\/span\u003e\u003c\/p\u003e\u003ch3\u003eAdditional Details\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eUPC: 6977162455648\u003c\/li\u003e\u003c\/ul\u003e","brand":"Deity","offers":[{"title":"Default Title","offer_id":52528587309330,"sku":"Deity-DA0406037H","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0379\/2529\/0029\/files\/SF1ActiveDirectionalAntenna_1.jpg?v=1784418107","url":"https:\/\/sixstarpsl.com\/products\/sf1-directional-antenna","provider":"SixStarPSL","version":"1.0","type":"link"}
