The GRN510 is a ZCG Scalar ground independent UHF detachable half-wave whip antenna engineered for reliable performance across the 500-520 MHz band. Delivering 4 dBi gain in a compact 310 mm form factor, this antenna is designed for robust communications in demanding mobile environments where durability, flexibility, and consistent signal performance are critical.
Utilising a half-wave ground independent design, the GRN510 does not require a ground plane, making it ideal for installation on vehicles, machinery, and non-metallic surfaces where conventional antennas may underperform. Its elevated performance profile supports Land Mobile Radio (LMR), industrial communications, and site-based UHF networks operating within the 500-520 MHz range.

The detachable whip design allows the radiating element to be easily removed when not in use or in high-risk environments where damage or vandalism may occur. This feature improves operational flexibility and reduces replacement costs in harsh applications such as mining, agriculture, defence, and heavy industry.
Supplied with a 4.7 m RG58A/U cable terminated in a UHF male PL259 connector, the GRN510 integrates seamlessly with standard UHF radio systems. The right-angle cable assembly enables clean installation, requiring a 16 mm mounting hole or suitable bracket for secure fitment.
Designed and manufactured in Australia to withstand harsh operating conditions, the antenna maintains stable vertical polarisation and consistent RF performance under vibration, movement, and environmental exposure.
Combining ground independent operation, higher gain performance, and detachable whip flexibility, the GRN510 from ZCG Scalar is a durable and practical solution for UHF communication systems in rugged and high-impact environments.
