The ZCG Scalar ZN3-77-10BLKR-TPM is a high-gain omnidirectional UHF CB antenna top designed and manufactured in Australia for dependable performance across the 477 MHz UHF CB band. Delivering 6.6 dBi gain, it provides excellent coverage for 4WD touring, off-road communication, fleet radio systems, and mobile UHF applications, ensuring consistent signal reach in both urban and remote environments. Constructed with a rugged black fibreglass radome and precision aluminium ferrule, the ZN3-77-10BLKR-TPM is built to withstand harsh Australian conditions, including UV exposure, dust, vibration, and salt-laden air, making it a durable solution for both land and coastal deployments. Its detachable design allows the antenna top to be easily removed for storage or transport, while a protective cap over the base prevents moisture ingress when the whip is removed. Supplied with a 0.5 m cable tail and dual 4.3-10 female connectors, the antenna integrates seamlessly with compatible bases, including the ZN3-SB-BLK, and can replace worn or damaged tops without the need for rewiring. Its omnidirectional 360° radiation pattern ensures uniform coverage, supporting reliable communication across all UHF CB channels with 100 W power handling. With its combination of Australian-made quality, high-gain performance, and robust design, the ZN3-77-10BLKR-TPM is an ideal choice for off-road enthusiasts, fleet operators, and professional UHF CB users seeking a durable, high-performance detachable antenna top.
