Deity SRD-Mini Portable 4-Channel RF (Antenna) Distributor 2×1→2-to-8 Active Split

DEITY SRD-Mini Portable 4-Channel RF Distributor

The DEITY SRD-Mini is an ultra-slim, portable active RF distribution system designed for location sound mixers and field production. It accepts two 50-Ω BNC inputs (A and B) and provides four SMA outputs per side (a 2→8 split), letting you power and route multiple passive or active antennas from a compact chassis.

Built with a CNC aluminum body and an active RF front end, the SRD-Mini compensates for gain loss and alerts you to RF overload conditions. It supports wide UHF coverage and multiple power options (USB-C, 4-pin DC, or pogo-pin Regional Power integration), making it bag-friendly for film, ENG and location sound setups.

Use the SRD-Mini to centralize antenna routing in a mixer bag, simplify antenna cabling, and supply power to active antenna circuitry while keeping the RF path low-noise and well isolated.

Key Features

• Function: Active 2→8 antenna/RF splitter (2 BNC inputs → 8 SMA outputs; split arranged as 1 A × 4 & 1 B × 4).
• Frequency Range: Ultra-wide UHF coverage (470 MHz – 1 GHz).
• Connectors: 2 × BNC inputs; 8 × SMA outputs; 1 × USB-C power; 4-pin DC (HRS4) power input; pogo-pin Regional Power interface (SPD-Mini compatible).
• Active Splitter: Low-noise active RF amps to compensate gain loss from splitting; indicator LEDs show overload condition per side and external power toggle per A/B side.
• Gain: +3 dB to +9 dB (adjustment/typical device gain range).
• Port Isolation: >20 dB minimum.
• Noise Figure: < 1.5 dB typical.
• Front-end tolerance: Front-end Max Input ~ +13 dBm; overload indication threshold ~ 0 dBm.
• Power Options: USB-C (5 V), 4-pin DC HRS4 (12–16.8 V), or Deity Regional Power pogo pins (SPD-Mini) for cable-less power integration.
• Construction: CNC aluminum chassis — compact and lightweight for bag use.
• Form Factor: Slim, bag-friendly profile for mounting/placement in sound bags or on carts.
