U20519 Used Diamond Antenna MX-62M Duplexer 1.6-56MHZ / 140-470MHz

U20519 Used Diamond Antenna MX-62M Duplexer 1.6-56MHZ / 140-470MHz

This pre-owned Diamond Antenna MX-62M duplexer is in good overall condition, exhibiting typical signs of prior installation and shack use. The die-cast aluminum housing remains structurally solid with crisp label lettering, the integrated coaxial pigtails retain excellent flexibility with intact strain-relief boots, and the RF connectors and threads are clean and undamaged.

The Diamond MX-62M is a high-performance passive RF duplexer designed to combine or split HF/50 MHz and 144/430 MHz signals. Operating across 1.6–56 MHz on the low-pass port and 140–470 MHz on the high-pass port, it allows operators to connect a multi-band radio with two antenna jacks (such as a Yaesu FT-857D, FT-991A, or Icom IC-7100) to a single multi-band antenna, or route a single transceiver output to separate HF and VHF/UHF antennas. Featuring high isolation (50 dB), minimal insertion loss (0.2 dB LPF / 0.3 dB HPF), and robust power handling up to 600 Watts PEP, the MX-62M is an essential station accessory for clean, loss-free RF routing.

Condition

• Cosmetic Condition: Good pre-owned condition showing standard handling marks on the extruded housing fins.

• Connectors & Leads: The SO-239 mix port threads and internal pin are clean, and the dual integrated coaxial pigtails terminate in clean PL-259 connectors with no pin corrosion or cable jacket fraying.

Key Features

• Wide Frequency Splitting: Low-frequency port covers 1.6–56 MHz (HF through 6 meters); High-frequency port covers 140–470 MHz (2 meters through 70 centimeters).

• High Power Handling: Rated for up to 600 Watts PEP across both ports.

• Low Insertion Loss: High-efficiency bandpass filtering delivers low loss (0.2 dB on LPF, 0.3 dB on HPF).

• High Port Isolation: Provides 50 dB of port-to-port isolation to prevent cross-band receiver desensitization or interference.

• Rugged Die-Cast Enclosure: Heavy-duty ribbed metal casing shields internal filter networks from external RF ingress.

• Convenient Pigtail Configuration: Built-in low-loss coax leads allow direct connection to closely spaced transceiver antenna jacks without bulky adapters.
