The ZN3-77-11BLKR-TPM UHF CB radio detachable antenna top is a high-performance 477 MHz solution designed to deliver an optimal balance between gain, size, and versatility. With a 6.6 dBi gain, this antenna top provides enhanced transmit and receive performance while maintaining effective coverage across both flat terrain and moderately hilly or built-up environments, making it a true all-round performer for UHF CB communications.
Engineered for flexibility, the ZN3-77-11BLKR-TPM can be paired with a compatible spring base such as the ZN3-SB-L-BLK or used as a direct replacement antenna top for existing ZN3 high-gain assemblies. This modular approach allows users to easily adapt their antenna configuration to suit changing operating conditions, whether prioritising range in open areas or maintaining signal consistency in more obstructed environments.
