Combining one directional LPDA (log-periodic dipole array) element and one bidirectional dipole element in a right-angle configuration, it captures both horizontally and vertically polarized signals. This advanced design eliminates multi-path fades and provides more consistent performance than two separate shark-fin antennas, especially in indoor and reflective environments. \u003ch2\u003eRF Venue DFINB Competitive Differences\u003c\/h2\u003e \u003cul\u003e \u003cli\u003ePatented polarization diversity design improves signal reliability and reduces RF dropouts\u003c\/li\u003e \u003cli\u003eCombines directional LPDA and bidirectional dipole in one compact unit\u003c\/li\u003e \u003cli\u003ePerforms the work of two antennas while saving space, setup time, and cost\u003c\/li\u003e \u003cli\u003eBroad frequency coverage from 470–698 MHz (UHF band)\u003c\/li\u003e \u003cli\u003eCompatible with any brand of wireless mic receiver using BNC connectors\u003c\/li\u003e \u003cli\u003eStandard mount threads support versatile positioning options\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eRF Venue DFINB Description\u003c\/h2\u003e Designed for professional wireless audio setups, the \u003cstrong\u003eDiversity Fin™\u003c\/strong\u003e antenna improves reception stability in even the most challenging RF environments. Whether deployed in live sound, house of worship, film production, or educational AV installs, its hybrid cross-polarized design ensures a more consistent and drop-free signal. The antenna’s dual-element architecture allows wireless receivers to maintain stronger diversity reception and minimize signal loss due to polarization shifts caused by moving performers or bouncing RF reflections.\r\nThe Diversity Fin is a drop-in upgrade from two standard paddle antennas, requiring just two coaxial cables (not included) to connect both polarization feeds to a diversity receiver or antenna distributor. Engineered for field and install flexibility, it features multiple mounting thread options and rugged, lightweight construction.\r\n\r\n\u003ch3\u003eDFINB Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eHybrid orthogonal antenna: 1 LPDA (directional) + 1 dipole (bidirectional)\u003c\/li\u003e \u003cli\u003eImproved polarization diversity eliminates multi-path fading indoors\u003c\/li\u003e \u003cli\u003eWide 228 MHz bandwidth for full UHF compatibility (470–698 MHz)\u003c\/li\u003e \u003cli\u003eSimple setup with two BNC connectors for diversity input paths\u003c\/li\u003e \u003cli\u003eCompact and lightweight design (1 lb) for portable or permanent installs\u003c\/li\u003e \u003cli\u003eMultiple mounting threads: 1\/4\"-20, 3\/8\"-16, 5\/8\"-27\u003c\/li\u003e \u003cli\u003eRugged black finish for discreet stage or venue placement\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eDFINB Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eOperating Frequency:\u003c\/strong\u003e 470–698 MHz\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBandwidth:\u003c\/strong\u003e 228 MHz\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 50Ω\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAverage Return Loss:\u003c\/strong\u003e -9.4 dB\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eLPDA Gain:\u003c\/strong\u003e 5 dBd | \u003cstrong\u003eBeam Width:\u003c\/strong\u003e 140° azimuth\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDipole Gain:\u003c\/strong\u003e 1.8 dBd | \u003cstrong\u003eBeam Width:\u003c\/strong\u003e 100° azimuth\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eConnectors:\u003c\/strong\u003e (2) BNC female\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMount Threads:\u003c\/strong\u003e 1\/4\"-20, 3\/8\"-16, 5\/8\"-27\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 12” L x 14.6” H (300mm x 370mm)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 lb (454g)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -9°F to 130°F (-23°C to 54°C)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cem\u003eFor any wireless microphone setup that demands maximum reliability and minimal dropouts, the RF Venue Diversity Fin delivers professional-grade performance in a compact, easy-to-integrate design.\u003c\/em\u003e\u003c\/p\u003e","brand":"RF Venue","offers":[{"title":"Default Title","offer_id":51583777276186,"sku":"115658O","price":660.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/rf-venue-dfinb--diversity-fin-polarization-antenna-for-wireless-microphone-systems-black_5eee68e4-5583-4f80-b755-d6ec870d5205.webp?v=1768529747","url":"https:\/\/squarecable.com\/products\/rf-venue-dfinb-diversity-fin-polarization-antenna-for-wireless-microphone-systems-black-1","provider":"SquareCable","version":"1.0","type":"link"}
