The ZCG Scalar ZM09-477-BLKR is a rugged marine UHF CB antenna engineered for clear, reliable communication on the water. Purpose-built for the Australian 477 MHz UHF CB band, this all-black 900 mm antenna delivers dependable performance for vessel-to-vessel and vessel-to-shore communications in demanding marine environments. Designed with a sleek, low-visibility profile, the ZM09-477-BLKR complements modern boats while offering the durability required offshore. Its marine-grade construction is built to withstand salt spray, UV exposure, vibration, and harsh weather, making it ideal for commercial operators, workboats, and recreational vessels alike. With a 2.1 dBi gain, the antenna provides a balanced radiation pattern optimised for marine use, supporting consistent coverage without the narrow focus of high-gain land-based antennas. This makes it well suited to dynamic maritime conditions where vessel movement and changing terrain can impact signal paths. Rated for 50 watts input power, the ZM09-477-BLKR easily handles standard marine UHF CB radios. It comes fitted with a 5-metre RG58A/U coaxial cable terminated in a UHF male (PL259) connector, ensuring straightforward integration with common marine radio installations while maintaining solid signal transfer. Whether used for safety communications, fleet coordination, or general boating chatter, the ZM09-477-BLKR provides a professional-grade solution for marine UHF CB radio communication. Combining performance, resilience, and a discreet all-black finish, it is a reliable choice for anyone who depends on clear communication at sea.
