Deity Microphones DG0406045J Active Antenna RF Distribution Kit

Overview

The Deity Microphones Active Antenna RF Distribution Kit is a complete professional RF signal management solution designed for location sound mixers, broadcast crews, ENG teams, film productions, and live-event professionals who depend on reliable wireless microphone performance. Combining the SRD-Mini portable antenna distribution system with two SF1 active directional shark fin antennas and four RF jumper cables, this kit provides everything needed to build a robust multi-receiver antenna system while reducing cable clutter, minimizing signal loss, and improving wireless reception in challenging RF environments.

Designed to serve as the front end of a professional wireless microphone system, the kit allows two external antennas to feed up to four wireless receivers through the SRD-Mini's active 2-to-8 signal distribution architecture. Unlike passive splitters that introduce signal loss, the SRD-Mini actively compensates for distribution losses to help maintain strong, consistent RF performance across all connected receivers.

Core Features

• Complete RF distribution kit includes the SRD-Mini antenna distribution system, two SF1 active shark fin antennas, and four SMA RF cables.
• Active 2-to-8 antenna distribution architecture supports up to four wireless receivers from a dual-antenna setup.
• Supports both passive and active antennas while providing switchable antenna bias power for external circuitry.
• SF1 directional antennas provide approximately 60° coverage to focus reception on talent and reduce unwanted RF interference.
• Selectable active antenna gain from -9 to +21 dB in precise 1 dB increments allows accurate compensation for cable loss.
• Wideband operation supports most professional UHF wireless microphone systems used worldwide.
• Multiple power options including USB-C, Hirose DC input, and compatible Deity power distribution systems.
• Durable CNC-machined aluminum construction provides lightweight portability for field production use.

Complete Wireless Reception Solution

The included SF1 directional shark fin antennas help improve wireless microphone reception by focusing RF coverage toward talent while reducing unwanted off-axis interference. Their log-periodic dipole array design provides approximately 60° directional coverage, making them ideal for productions that require dependable wireless performance across large venues, stages, and filming locations.

Active Gain Control

The SF1 antennas feature adjustable active gain from -9 to +21 dB in precise 1 dB increments, allowing compensation for cable loss while maintaining optimal RF performance. An integrated overload indicator provides visual feedback when RF levels become excessive, and the antennas can continue operating in passive mode when DC bias power is unavailable.

Professional RF Distribution

The SRD-Mini distributes signals from two antennas to up to four wireless receivers through an active 2-to-8 architecture that compensates for splitter loss. Independent antenna power switching on the A and B sides provides flexibility when working with active antennas and other RF accessories, while its wide operating range supports compatibility with most professional UHF wireless systems.

Built for Production

The SRD-Mini features a lightweight CNC-machined aluminum chassis designed for sound bag integration, while the SF1 antennas offer IP54-rated weather resistance and a vented design that reduces wind loading during outdoor deployments. Combined with the included right-angle SMA RF cables, the kit is ready for professional field and broadcast applications.
