Which brand do I need - RFI or ZCG?


  • 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 antenna's solid copper internals are practically unbreakable, where as circuit-board designs can fracture with extended use on extremely rough terrain.
