Why the Oricom UH400R is the Best Heavy Duty 12/24V UHF CB Radio for Trucks & 4WD in Australia
This beast of a radio redefines mobile UHF with its automatic 12/24V switching that plugs into any rig without adapters, while the external heat sink keeps it blasting 5W non-stop through summer scorches or overloads. The large colour LCD (green/amber backlit) cuts glare for night drives on the Eyre Hwy, and priority scanning locks on Ch 5/35 emergencies without missing your convoy. Die-cast rugged chassis laughs off vibrations from gravel roads or quarry blasts, with 38 CTCSS codes blocking interference for crystal-clear team talk. Duplex capability hits local repeaters for 50+ km range boosts, and 200 programmable RX channels let you monitor LMR or telemetry. Auto level control ensures consistent audio over wind roar or engine hum—perfect for FIFO hauls or outback tours.
