The CO-301N<\/strong> is a professional-grade, heavy-duty 3-way coaxial switch designed to let radio operators route their RF signals seamlessly between up to three different antennas or transceivers. Engineered for clean electrical performance, this high-quality selector operates smoothly at frequencies up to 800 MHz, making it the perfect routing solution for HF, VHF, and UHF amateur radio stations, commercial dispatch centers, and maritime communication setups. By using a mechanical selector instead of splitting cables, the CO-301N maintains maximum signal integrity with virtually no insertion loss.<\/p>\n

At the heart of the CO-301N is its low-loss N-Type female connector configuration. These gold-plated and silver-plated contact surfaces ensure stable, weatherproof connectivity and superior performance compared to standard UHF connectors. The switch is built to handle substantial RF power, supporting up to 1000 Watts PEP in the lower HF bands (up to 150 MHz) and stepping down to a highly reliable 150 Watts PEP in UHF ranges up to 1500 MHz. Designed for high isolation (60dB at 500 MHz) and exceptionally low Voltage Standing Wave Ratio (VSWR of 1.1:1), this switch prevents signal bleed-through and ensures your expensive transceiver is shielded from reflective feedback.<\/p>\n

Housed in a rugged, cast metal enclosure weighing 575 grams, the CO-301N is designed to last a lifetime in active radio shacks or mobile stations. Its compact footprint of 84 x 95 mm features integrated mounting holes, allowing you to secure the switch firmly to a workbench, radio rack, or partition wall. A heavy-duty tactile rotary lever provides crisp, mechanical feedback when switching channels. Important safety notice: Never reposition the rotary switch while the radio is actively transmitting, as this can cause permanent electrical arcing and damage to both the switch and your transceiver.<\/em> For PL-259\/UHF installations, the alternative PL-connector version (Ref. 0485) is also available.<\/p>\n
