The Diamond HC200S is a premium, ultra-lightweight UHF monoband antenna designed for high-performance operation within the broad 350 to 520 MHz frequency spectrum. Ideally suited for compact transceivers, commercial land mobile radios, and portable scanning equipment, this pocket-sized antenna offers exceptional mobility without compromising signal performance. The base is engineered with a standard SMA male connector, ensuring a direct, secure, and low-loss physical connection to standard handheld radios.
Operating as a highly efficient 1/4λ (quarter-wave) element, the HC200S delivers a consistent gain rating of 2.15dBi across its working bandwidth. Despite its exceptionally compact length of only 0.20 meters (20 cm) and a nominal weight of just 27 grams, it handles a maximum continuous power rating of up to 10W. With a standard 50Ω impedance, the antenna maintains a tight voltage standing wave ratio (VSWR) of less than 1.5:1 at resonance, shielding your RF power amplifiers from high reflective power damage and ensuring stable signal propagation.
