Icom IC-455 UHF CB Radio Australia – Compact 5W/1W 80Ch MIL-SPEC Mobile with ANC Mic & LMR Ready for Extreme Conditions
Need a battle-tested Icom IC-455 UHF CB radio Australia that's LMR-ready and engineered for the toughest Aussie extremes? The IC-455 is the ultimate compact mobile UHF CB for truckies on the Great Northern Hwy, site crews in Pilbara heat, or fleet managers demanding MIL-SPEC durability – delivering switchable 5W/1W on 80 narrowband channels with active noise cancelling mic, automatic repeater scan, and 48 user RX channels for LMR/telemetry (400-520MHz licensed). Japanese-made precision: die-cast aluminium chassis with heavy-duty heat sink, white backlit LCD for glare-free viewing, CTCSS/Selcall for private alerts, and front-mounted speaker for clear audio. Comes with 5-year warranty, HM-244 ANC mic, and free shipping over $99. Extreme comms – mission-critical reliability!
Why the Icom IC-455 is the Best MIL-SPEC 5W/1W UHF CB Mobile Radio for Trucks & Sites in Australia
This indestructible unit redefines mobile UHF with its MIL-SPEC 810F construction that survives -30°C to +60°C shocks, vibrations, and drops, while the heavy-duty heat sink maintains 5W output through 50°C furnace hauls or overloads. The white backlit LCD cuts glare for night ops on the Barkly Hwy, and automatic repeater scan finds duplex boosts without manual hunting. Die-cast aluminium chassis (125x29x160mm) fits tight dashes, with 13.8V DC plug-and-play for 12/24V rigs. Tailored for Oz extremes: ANC mic silences wind or diesel rumble for crisp transmission, CTCSS/Selcall pings specific users, and 48 RX channels monitor LMR or telemetry for licensed fleets. Silent standby with tones saves battery, and front speaker blasts alerts over engine noise—perfect for FIFO shifts or remote patrols.
Real user shout: "IC-455's MIL-SPEC build and ANC mic kept my comms flawless during a NT cyclone – heard the evacuation call over 40km winds!" – Ryan, Mining Supervisor.
