Radio operators, listen up! This Diamond MX72A duplexer is exactly what you need for clean signal separation. It handles three frequency ranges - 1.6-30MHz and 140-150MHz on the low pass side, and 400-460MHz on the high pass side. The connectors are solid with a mixed N-Jack female, PL-259 with 12-inch cable, and N-Male with another 12-inch cable. Power handling is impressive - 400W CW on low pass, 150W on band pass, and 100W on high pass, with PEP ratings up to 1KW, 400W, and 250W respectively. The isolation between bands is a solid 60dB, which really helps prevent interference between your different radios. Loss is minimal at just 0.1dB across all bands. The aluminum case has this nice black finish that looks professional and helps with heat dissipation. Perfect for setups with radios like the ICOM IC-706/7000 series or Yaesu FT-857 series where you want to run multiple bands through a single antenna. It eliminates the need for antenna switches, which simplifies your station setup. The build quality is typical Diamond - robust and reliable. I've been running one of these for about a year now with zero issues. The cables are decent quality and the connectors are well-made. If you're serious about your radio setup and want clean signal separation without constantly swapping antennas, this duplexer is absolutely worth the investment.
