The Daiwa CS-201GII 2-Position Coax Switch is a professional-grade RF component designed to provide reliable and versatile coaxial routing for demanding device systems. Whether you're operating an HF base station, a VHF/UHF setup, or a dual-device environment, this switch allows efficient management of two coax lines while preserving excellent signal quality. Covering frequencies from DC to 2 GHz, it accommodates a wide range of use cases, from HF DXing to advanced scanner and transceiver configurations. One of the key strengths of the CS-201GII is its power-handling capability. It supports 1.5 kW continuous wave (CW) up to 30 MHz, 250 W CW up to 1 GHz, and 150 W CW at frequencies up to 2 GHz, giving you confidence even under high-power transmission scenarios. The switch is engineered for safety: the unused port is automatically grounded, protecting against stray RF and ensuring that your active path remains clean and isolated. From an RF performance perspective, this switch delivers low insertion loss — less than 1.2 dB at 1.2 GHz — which helps maintain strong signal strength and prevents degradation. At the same time, it provides up to 50 dB of isolation at 1 GHz, reducing crosstalk between the two paths and maintaining clean signals for receive or transmit. These characteristics make it especially valuable in multi-device or multi-antenna systems, where bleed-over between lines can degrade performance or cause interference. The CS-201GII is built to last. Its rugged die-cast metal housing ensures durability in both base-station and portable installations. The rotary switch mechanism is smooth and precise, allowing you to manually toggle between two antennas or two devices with ease. Gold-plated N-type female connectors provide secure, low-loss connections that are well suited for professional device environments. Because of its wide frequency range, high isolation, and solid power ratings, this coaxial switch is popular among amateur device operators, scanner enthusiasts, and commercial communications users. No matter whether you need to switch between two antennas or route to different devices, the CS-201GII is a dependable, high-performance component that supports long-term, clean RF switching.
