Diamond MX-72N Duplexer – Radioworld UK

Diamond MX‑72N 2m/70cm Duplexer – High‑Performance Multi‑Band Signal Management.


Trustpilot

The Diamond MX‑72N is a versatile 2m/70cm duplexer engineered for simultaneous operation across multiple bands. Featuring three port options (LPF/BPF/HPF), it supports a wide frequency range:

  • Port 1: 1.6–30 MHz & 140–150 MHz

  • Port 2: 400–460 MHz

  • Port 3: Flexible high‑pass filtering

Delivering robust performance, the MX‑72N handles CW power outputs of 400W, 150W, and 100W, with PEP ratings of 1kW, 400W, and 250W, respectively. Loss is minimal at 0.1 dB, while isolation between ports reaches 60 dB, ensuring clean and efficient signal separation.

Connectivity is enhanced with SO‑239 and N‑TYPE connectors, plus PL‑259 and 12" 5D cable options (compatible with Yaesu AD‑3). An included N‑Male connector with 12" 5D cable adds flexibility for varied setups.

Compact, durable, and precise, the MX‑72N is ideal for amateur radio operators and enthusiasts seeking reliable duplexing for multi‑band communication.
