The S4B42-1CSS from ZCG Scalar is a high-performance broadband Air Band dipole array antenna engineered for reliable ground-to-air communications across the full 118-137 MHz aviation band. Designed as a 4-stack folded dipole array, it utilises an integrated internal power divider to ensure precise phasing and consistent radiation characteristics across the entire operating range, delivering stable, wideband performance without compromise.
Built in Australia from 304 stainless steel, the antenna is designed for long-term durability in exposed environments where corrosion resistance and mechanical stability are critical. With a robust 500W power handling capability and a precision-tuned 7.5 dBd high gain output, the S4B42-1CSS provides strong, consistent signal coverage ideal for both civil aviation infrastructure and military Air Band communication systems. Its optimised design maintains effective performance with low VSWR (better than 1.5:1) across the full band, supporting clean transmission and reception in demanding operational conditions.

The antenna is fitted with an N-type female RF connector and is engineered for fixed installation use, ensuring stable electrical performance in permanent deployments. Its vertical array configuration is supported by a rigid mounting design requiring bottom, centre, and top clamp support, eliminating mechanical flex and maintaining precise element alignment over time. At 6.0 metres in length, it provides a controlled radiation pattern suited to reliable ground-to-air coverage in airfield, defence, and aviation communication networks.
Within the ZCG Scalar antenna range, the S4B42-1CSS represents a purpose-built solution for Air Band base station antenna systems, delivering dependable wideband performance, structural integrity, and long service life in mission-critical communication environments.
