The ZN3-77-11W from ZCG Scalar is a high-performance UHF CB radio antenna engineered for reliable communication across the 477 MHz UHF CB band, delivering strong, consistent coverage for both mobile and fixed installations. Designed to provide an optimal balance between height and performance, it offers a powerful 6.6 dBi gain that performs effectively across flat and moderately hilly terrain, making it a versatile solution for a wide range of operating environments. Constructed as a heavy-duty fibreglass antenna with a detachable whip design, the ZN3-77-11W is built for durability in harsh Australian conditions while offering practical flexibility in the field. The removable radiator allows the antenna to be easily detached when not in use or in situations where impact risk, low clearance, or vandalism may be a concern. This feature makes it particularly well suited to 4WD vehicles, transport fleets, agricultural equipment, and remote area communications where both performance and protection are critical. With a 100W power handling capability, the antenna supports higher power UHF CB systems, ensuring strong transmission performance when it matters most. It is supplied with an integrated 5 metre coaxial cable assembly terminated with a UHF male (PL259) connector, enabling straightforward installation into standard UHF CB radio setups. The 1.2 metre overall height provides enhanced signal reach while maintaining manageable vehicle clearance. The antenna?s omnidirectional radiation pattern ensures reliable all-round communication, while its robust construction supports long-term use in demanding environments. A secure grub screw mechanism allows for quick removal of the whip, and when detached, a protective cap can be fitted to prevent dust and moisture ingress into the base assembly. As part of the ZCG Scalar heavy-duty UHF CB antenna range, the ZN3-77-11W delivers a durable and high-performing detachable UHF CB antenna solution, offering strong signal performan
