Duplexer HF-60 MHz / 140-470 MHz SO-239
Use an HF, 2 Meter or 440 MHz antenna with a separate HF, 2 Meter or 440 MHz transceiver without a built-in duplexer. Or use two dual band antennas with a dual band transceiver with only one RF output. Heavy duty diecast enclosure houses low pass networks that separate/combine 144/440 MHz signals. Ports are 50 Ohms, units handle 200 Watts PEP. 4916S has SO-239 connectors, but handles 600 Watts PEP.
