The Daiwa CS-401 4-way coaxial switch<\/strong> is a commercial-grade, high-isolation radio frequency routing component engineered to manage multi-antenna distributions within professional radio base stations and advanced laboratory environments. Utilizing an ultra-low-loss manual rotary selector matrix, this heavy-duty hardware platform allows operators to comfortably route a single mainline input transceiver across 4 independent antenna outputs<\/strong>. It serves as an essential logistics procurement component for municipal emergency dispatch hubs, tactical telecommunication shelters, commercial communication rooms, and high-volume B2B radiocommunication accessory wholesale networks looking to secure premium coaxial routing assets.<\/p>\n

The precise mechanical build of the CS-401 provides outstanding electrical integrity across a wide frequency range stretching up to 500 MHz<\/strong>, delivering total operational coverage across the HF, VHF, and UHF bands. Built to safely withstand legal-limit transmission output from high-power linear amplifiers without internal arcing or structural heating, the switch claims a massive **maximum power rating of 2.5 kW (PEP) or 1 kW (CW)** continuous duty. To preserve weak signals and ensure total protection against downstream co-channel interference, the internal cavity layout delivers an unyielding **isolation index of \u2265 60 dB at 200 MHz**, while ensuring highly efficient energy transmission with a negligible **insertion loss of \u2264 0.2 dB**.<\/p>\n

Housed inside a ruggedized, fully shielded industrial metal cavity enclosure, this high-performance antenna switch routes signals along a uniform 50 \u03a9 characteristic impedance<\/strong> path, keeping system variance at an absolute minimum with a **Voltage Standing Wave Ratio (SWR) of \u2264 1.2:1**. The rear interface is populated entirely with premium heavy-duty SO-239 PL Female connectors<\/strong> (1x Input path, 4x Output paths) designed to mate smoothly with heavy-gauge PL-259 male plugs. Delivered as a comprehensive, shelf-ready solution, the package completely **includes all necessary mounting hardware** for secure anchoring to workshop benches, control consoles, or equipment racks, guaranteeing immediate technical system alignment and absolute multi-shift field readiness.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
