Manufactured in Australia the ZN3-77-12W white heavy-duty UHF CB radio detachable antenna is engineered for superior 477 MHz performance, delivering an impressive 8.1 dBi gain for maximum transmit and receive range over flat terrain. Designed for long-distance communication, this high-gain antenna is ideal for open, unobstructed environments such as plains, highways, and rural operations, providing reliable coverage where lower-gain antennas may struggle.
Featuring a detachable top, the ZN3-77-12W allows users to easily reduce gain when necessary, making it versatile for varying communication scenarios. The top can be removed quickly by releasing the tension grub screw and unscrewing the antenna section, enabling adaptability with basic tools and minimising complex adjustments. The robust spring base accommodates standard vehicle mounts, while the included PVC cap protects the connector from water and dirt ingress, ensuring durability in harsh conditions.
