The ZN3-77-04-TPM is a compact, high-performance detachable UHF CB whip antenna engineered for the Australian 477 MHz UHF CB radio band. Delivering 2.1 dBi gain, this 400 mm whip provides reliable short to medium range communications, making it ideal for convoy driving, off-road touring, worksites and general mobile UHF CB installations. Rated at 100 Watts, the ZN3-77-04-TPM supports high-power UHF CB radios across all 80 channels within the 477 MHz spectrum.
