The ZN1-77-04 from ZCG Scalar is a high-performance UHF CB radio fibreglass whip antenna engineered for reliable communication across the 477 MHz UHF CB band, delivering strong omnidirectional coverage for both mobile and fixed installations. Designed for demanding field use, it provides an effective balance of high gain performance, mechanical durability, and a compact physical profile.
Constructed with a heavy-duty fibreglass radiator, the ZN1-77-04 is built to withstand harsh Australian environmental conditions, making it well suited to regional travel, off-road driving, farming, transport fleets, and recreational 4WD communications. Its phased coil design ensures efficient radiation characteristics, delivering a high-performance 6.6 dBi gain output while maintaining stable omnidirectional signal propagation across varied terrain including flat and semi-hilly environments.
