The Active UHF Directional Antenna with FlexiMount Base Kit from B&H consists of a Shure UA874 UHF antenna and a Dinkum Systems FlexiMount 9-link microphone stand. The stand securely mounts the Shure antenna and can be accurately positioned for optimum audio results. It is designed for quick setup in several environments.

  • Shure UA874 Active Directional Antenna

    The Shure UA874 Active Directional Antenna uses a log periodic dipole array to offer enhanced reception when directed toward the desired coverage area. An integrated amplifier and four gain settings compensate for varying degrees of coaxial cable signal loss. The UA874 can be mounted on a microphone stand, suspended from the ceiling or mounted to a wall using the integrated swivel adapter bracket.

    Compatible with all Shure wireless receivers and antenna distribution systems that provide 12 V DC bias
    Four-position gain selector switch
    Low-noise signal amplifier that compensates for transmission loss in coaxial cable
    Integrated threaded adapter that mounts easily to microphones stands

  • Dinkum Systems 3013 FlexiMount

    The Dinkum Systems FlexiMount gives musicians and professional audio technicians a quick and simple mic mounting solution. It is ideal for the quick set-up required by roadies, documentary filmmakers, audio engineers, or on-the-go podcasters.

    FlexiMount attaches easily to surfaces such as tables, C-stands, lighting grids, and drum kits. Its large custom spring clamp accommodates a mounting surface up to 2" thick, providing a secure base for the durable and length-adjustable 9-link, 12" long arm. The strong and flexible arm does not require tools to lengthen or shorten as it simply pops apart and presses back together to get the length you want.

    FlexiMount can be bent into nearly any shape or position, and attached to a standard 3/8"-16 microphone shock mount. This mount has become an essential item in the kit of an audio technician intent on capturing quality sound on the set and in the field, and is compatible with many RF antennas.
