This is the heaviest duty bullbar antenna available, designed for the harshest environments and rough treatment. Weighing in at 1.3kg and 1200mm length, this antenna has solid copper radiating elements for maximum durability, and an allen-key removable whip design for low-clearance areas, and for safe storage.

Typical Usage

ZCG Scalar bullbar antennas are designed with solid copper radiating elements, designed to last on even the toughest of corrugated roads. You'll typically see RFI brand antennas on fleet and emergency vehicles in regional and rural areas, but if you frequent unsealed roads or rough terrain ZCG's bullbar antenna series are the preferred option. The ZN3-SGDB antenna's solid brass internals are practically unbreakable, where as circuit-board designs can fracture with extended use on extremely rough terrain.
The high quality electro-polished stainless steel barrel spring dampens vibrations while travelling. 5 metres of RG58 low loss cable side exits from the aluminium mount ferrule, pre-terminated with an FME Female connector for attaching to your cradle or patch lead. To install, simply secure the antenna firmly into any bracket with a 13mm (½”) minimum diameter hole using the bolt and washer provided. The typical mounting point for this model is to a vehicle bull bar, but many other mounting options are available with our extensive range of vehicle brackets. Australian Network Compatibility
