Audio Wireless AD224-P 4-Way Antenna Distribution System

Feeding up to four diversity receivers from one pair of antennas, the Audio Wireless AD224-P is a 4-way antenna distribution system that also powers other gear through four switched Hirose DC outputs.

Its custom-tuned band-pass filters clean up the RF within the operating band before the signal reaches the receivers, so unwanted signals in a crowded spectrum stay out. The single pair of antennas replaces the antennas each receiver would otherwise carry in the bag.

Two BNC antenna inputs take standard low-loss coaxial extension cables, and eight SMA outputs (2 × 4) feed the receivers. Gain is adjustable in 1 dB steps from +6 dB to -10 dB, and power to each active antenna switches on and off separately. It works with full-digital, digital-hybrid, and analog radio mic receivers.

The AD224-P runs on 10 to 18 V DC through a 4-pin Hirose input. Each Hirose output is individually fused and switches on and off from the TFT display menu, with up to 3 A shared across them. A built-in voltmeter shows the input voltage.
