Bandpass filters simultaneously pass RF in both directions through the common SO-239 connector, while providing 40dB of isolation between the low-pass and high-pass ports. The unused port can remain open, though terminating with a dummy load is recommended for best results.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSimultaneous dual-band operation: 1.3–150MHz and 200–480MHz\u003c\/li\u003e\n\u003cli\u003eSuited to HF\/2m and 220MHz\/70cm multi-band installations\u003c\/li\u003e\n\u003cli\u003e40dB isolation between ports\u003c\/li\u003e\n\u003cli\u003e600W PEP on the low-pass port; 400W PEP on the high-pass port\u003c\/li\u003e\n\u003cli\u003eLow insertion loss: \u0026lt;0.2dB (LPF) and \u0026lt;0.3dB (HPF)\u003c\/li\u003e\n\u003cli\u003e50 Ohm impedance\u003c\/li\u003e\n\u003cli\u003eCommon: SO-239 | Low pass: PL-259 | High pass: PL-259\u003c\/li\u003e\n\u003cli\u003eTX and RX from two radios simultaneously into a dual-band antenna\u003c\/li\u003e\n\u003cli\u003eCombine a dual-band radio with separate outputs into a single dual-band antenna\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLPF Passband: 1.3–150MHz\u003c\/li\u003e\n\u003cli\u003eHPF Passband: 200–480MHz\u003c\/li\u003e\n\u003cli\u003eLPF Insertion Loss: Less than 0.2dB\u003c\/li\u003e\n\u003cli\u003eHPF Insertion Loss: Less than 0.3dB\u003c\/li\u003e\n\u003cli\u003eMaximum Input Power: LPF \/ 600W (PEP)\u003c\/li\u003e\n\u003cli\u003eMaximum Input Power: HPF \/ 400W (PEP)\u003c\/li\u003e\n\u003cli\u003eIsolation: 40dB\u003c\/li\u003e\n\u003cli\u003eCommon Connector: SO-239\u003c\/li\u003e\n\u003cli\u003eLow Pass Port: PL-259\u003c\/li\u003e\n\u003cli\u003eHigh Pass Port: PL-259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Comet","offers":[{"title":"Default Title","offer_id":57666765029720,"sku":"MOON-48-146","price":44.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/cma-cf-142.jpg?v=1783505872","url":"https:\/\/kamsat.co.uk\/products\/comet-cf-142-duplexer","provider":"Kamsat","version":"1.0","type":"link"}
