The GRN410 is a ZCG Scalar ground independent UHF detachable half-wave whip antenna engineered for reliable performance across the 400-420 MHz band, including compatibility with Land Mobile Radio (LMR) and Government Radio Network (GRN) systems (403-420 MHz). Delivering 4 dBi gain in a compact 360 mm form factor, this antenna is designed for consistent communications in demanding mobile and field-based environments.
Utilising a half-wave ground independent design, the GRN410 does not require a ground plane, making it ideal for installation on vehicles, plant equipment, and non-metallic surfaces where traditional antennas may not perform effectively. Its tuned frequency range supports public safety networks, government communications, and private UHF systems operating within the 403-420 MHz spectrum across Australia.

The detachable whip design allows the radiating element to be removed when not in use or in high-risk environments where damage or vandalism may occur. This feature improves operational flexibility and reduces maintenance and replacement costs in harsh applications such as mining, agriculture, emergency services, and defence-related deployments.
Supplied with a 4.7 m RG58 cable terminated with a UHF male PL259 connector, the GRN410 integrates easily with standard UHF radio systems. The right-angle cable assembly supports clean installation, requiring a 16 mm mounting hole or suitable bracket for secure fitment.
Built to withstand vibration, movement, and environmental exposure, the GRN410 maintains stable vertical polarisation and dependable RF performance in real-world operating conditions.
Combining GRN/LMR compatibility, ground independent operation, and detachable whip flexibility, the GRN410 from ZCG Scalar is a robust and cost-effective solution for UHF communications in critical and high-demand environments.
