Uniden UM455VHF: The Flagship of Marine Communication

Take command of your offshore safety and communication with the Uniden UM455VHF. Designed in Japan and engineered for the harshest marine environments, this fixed-mount radio is the ultimate tool for boaters, fishermen, and commercial operators who demand crystal-clear reliability when it matters most.

Key Features

• Built for the Elements: The UM455VHF features a rugged, watertight housing and a submersible speaker microphone. Certified to the global JIS7 water-resistance standard, it can withstand submersion in 1 meter of water for up to 30 minutes.

• Dual-Speaker Technology: Never miss a transmission. This unit is equipped with two speakers—one at the front of the main unit and a second built directly into the microphone handpiece—providing superior audio clarity even in high-wind or engine-heavy environments.

• Digital Selective Calling (DSC) Class D: Enhance your safety with Class D DSC functionality. In an emergency, a single press of the red Distress Button automatically broadcasts your MMSI number and GPS coordinates to all nearby vessels and rescue authorities.

• GPS Integration: Ready for navigation, the UM455VHF allows for optional GPS receiver input to display your position or output received data to a chart plotter.
