Uniden UM435 Fixed Mount VHF Radio - White

The Uniden UM435 is a 25-watt fixed-mount VHF with a shorter chassis than many helm radios, which makes it one of the easier units to fit behind a crowded or shallow dash. It adds submersible protection and NMEA 0183 wiring for boats that want the radio talking to a GPS or chartplotter.

Who it’s for

• Helms with limited depth behind the panel
• Boats with an existing GPS or chartplotter that can share position data over NMEA 0183
• Boaters crossing into Canadian waters, thanks to Canadian marine channel support

Key features

• 25-watt maximum transmit power
• IPX8/JIS8 submersible protection
• NMEA 0183 input and output for position data sharing
• Canadian Marine Broadcast "B" channels and international 4-digit channels
• Full dot-matrix display and microphone-mounted controls

Setup tips

• Register an MMSI before first use. DSC distress calls only identify your boat if an MMSI number is programmed into the radio. Recreational boaters in U.S. waters can get one free from BoatUS, Sea Tow, or the U.S. Power Squadrons; boats traveling internationally need one through the FCC.
• Range comes from the antenna. VHF is line-of-sight, so antenna height and good coax matter more than anything else. See our VHF antenna guide.
• Know your channels. Channel 16 is for hailing and distress, Channel 70 carries DSC data only, and the WX channels carry NOAA weather. See the VHF channel guide.

Before ordering

Confirm the mounting depth available behind your dash, your 12V power run, the antenna connection, and how you will wire NMEA 0183 if you want GPS position fed to the radio for DSC calls.
