The Daiwa CS201GII is a professionally engineered, commercial-grade 2-way coaxial antenna switch designed to provide seamless RF path switching and superior isolation across an exceptionally wide frequency spectrum. Featuring an advanced cavity construction design, this premium selector switch allows operators to route a single radio transceiver to two separate antenna systems, or conversely, connect two independent radios to a single shared antenna. By utilizing a specialized internal shielding cavity, the switch significantly minimizes adjacent port bleeding, preventing intermodulation and protecting delicate receiver front-ends from accidental transmitter overload.
Built for long-term reliability in high-performance base stations and commercial radio rooms, the CS201GII features a heavy-duty mechanical frame finished in a smart chrome coating. The robust internal switching mechanism delivers a solid tactile snap, ensuring positive contact alignment and low-resistance electrical continuity with every flip. By deploying this high-integrity hardware component, radio station technicians can cleanly eliminate the constant wear and connector stress associated with manual cable patch-panel swapping.
On the electrical layer, the switch operates with remarkable efficiency from DC all the way up to 1.3GHz, making it highly versatile for HF, VHF, UHF, and SHF microwave operations. It boasts a substantial power-handling threshold, comfortably managing up to 1.5kW on HF frequencies and scaling down safely to 150 watts in the gigahertz spectrum. Equipped with premium, ultra-low loss N-type female connector sockets and optimized for a standard 50 Ohm system impedance, this turnkey RF switch delivers exceptional VSWR stability and negligible insertion loss to ensure absolute signal integrity for your network infrastructure.
