The ZN4-77-06S is a high-performance 477 MHz UHF CB antenna engineered for mobile and off-road applications, delivering reliable communications wherever you go. Its elevated feed design and 6.6 dBi medium gain provide strong, consistent signal transmission, making it ideal for vehicles, fleet radios, and emergency service units. Built around a heavy-duty stainless steel parallel spring, the antenna absorbs shocks and flexes without damage, ensuring durability in rugged conditions and harsh environments.
Designed as a ground-independent UHF CB antenna, the ZN4-77-06S does not require a metal mounting surface, giving maximum flexibility for installation on trucks, SUVs, industrial machinery, or any mobile platform. With a 900 mm length, 4.5 m cable, and standard UHF male PL259 connector, it integrates easily with any UHF CB radio featuring a female connection, offering plug-and-play convenience for quick deployment.
