The OB-4.7 UHF CB antenna mount base with 4.7 metre cable is the industry standard vehicle antenna cable assembly engineered for reliable mobile and fixed radio installations. Manufactured in Australia by ZCG Scalar, this mount base provides consistent build quality and dependable long-term performance, offering a locally made alternative to imported antenna cable assemblies. Supplied with 4.7 metres of RG58A/U coaxial cable (longer alternatives available) and terminated with a UHF male PL259 connector (or specify termination requirements), the OB-4.7 ensures direct compatibility with standard 477 MHz UHF CB radios and commercial two-way radio systems. The integrated 5/16"-26 brass male thread allows secure fitment to any whip antenna featuring a matching 5/16"-26 female threaded ferrule, including common UHF CB and 27 MHz CB whip antennas. Designed for vehicle installation on bull bars, mirror brackets, roof mounts or suitable panels, the OB-4.7 requires a minimum 16 mm mounting hole or compatible bracket. Its solid brass threaded stud and durable cable construction provide reliable mechanical retention and stable RF performance in high-vibration environments such as 4WDs, light trucks, agricultural machinery and fleet vehicles. The assembly can also be utilised in fixed position installations where a 5/16"-26 threaded whip antenna is required. The OB-4.7 delivers a practical, installer-ready UHF CB mounting base with extended cable length, combining Australian manufacturing, industry-standard thread compatibility and vehicle-grade durability for professional radio communications applications.
