ZCG RA4 low PIM corner reflector

ZCG Scalar has expanded its Australian-made antenna portfolio with the RA4 series low PIM broadband corner reflector, designed to deliver dependable performance for UHF base stations across 400–520 MHz.

Engineered to provide 10 dBd gain with a high front-to-back ratio, the product enables focused coverage while minimising interference. Built from lightweight, fully welded, all-aluminium open grid, the antenna is designed to withstand harsh weather conditions while maintaining a compact 750 x 655 mm footprint. With up to 500 W input power handling and a 4.3-10 female connector, it integrates seamlessly into mission-critical networks for emergency services, utilities, mining and infrastructure operators.

The product was developed in collaboration with a leading global communications partner to overcome reliability issues experienced with the latter’s existing network equipment. ZCG worked closely with the partner’s engineering team to tailor the antenna’s design to their specific operational requirements; this collaborative approach meant the antenna met the customer’s requirements while optimising coverage and signal clarity. By combining ZCG’s in-house manufacturing expertise with the partner’s network insights, the project resulted in a high-performance, durable antenna solution that met both technical and environmental demands.

Designed and manufactured in-house at ZCG’s East Gippsland facility, the antenna demonstrates the company’s ongoing commitment to high-quality, locally made solutions.
