Compact High-Isolation Duplexer for HF, VHF and UHFThe Diamond MX-72N is a compact, high-performance duplexer covering HF (1.6–30MHz), VHF (49–150MHz), and UHF (400–460MHz) simultaneously from a single SO-239 common port. With 60dB of isolation on the low-pass port and a 1kW PEP power rating on HF, it punches well above its compact 220g form factor. The mixed connector configuration — PL-259 on the LPF port and Type N on the HPF port — makes it a versatile choice for installations using different feedline connector types. Extended receive-only passbands (LPF: 1.6–225MHz, HPF: 340–1000MHz) provide additional monitoring flexibility. Supplied with 35cm of 5D-2VS coaxial cable.Key Features Simultaneous operation: 1.6–30MHz (LPF), 49–150MHz (LPF), and 400–460MHz (HPF) Extended receive-only passbands: LPF 1.6–225MHz, HPF 340–1000MHz 60dB+ isolation on the LPF port 1kW PEP on HF (1.6–30MHz); 400W PEP on VHF; 250W PEP on UHF Low insertion loss:
