Compact Marine VHF with GPS and AIS Transponder

The Garmin Signal VHF 400 is a premium marine radio designed to help boaters stay connected, informed, and safer on the water. Built with a modern 3.5 inch color touchscreen display, it delivers an intuitive user experience while taking up minimal space at the helm. For sailors and cruisers who depend on reliable communication, the VHF 400 combines advanced VHF radio performance with an integrated Class B AIS transponder, allowing you to see and be seen by other AIS equipped vessels in busy waterways and offshore passages.

Situational awareness is one of the VHF 400's standout features. Its built in AIS transponder displays nearby vessel information including range, course, speed, and potential crossing situations, helping captains make more informed navigation decisions. Class D Digital Selective Calling adds another layer of safety by allowing the radio to quickly transmit distress information when needed. The AIS interface also makes it easy to contact other AIS equipped vessels directly from the display, streamlining communication on the water.

Clear communication is essential in challenging marine environments, and the VHF 400 is engineered to deliver exceptional audio quality. Adaptive noise cancellation uses advanced processing to reduce wind, wave, and engine noise, making incoming transmissions easier to understand. Automated squelch helps eliminate unnecessary radio chatter, while audio playback allows users to replay missed transmissions from the previous three minutes. Advanced watch modes continuously monitor channel 16 along with selected favorite channels, helping sailors stay aware of important traffic and weather information.

Installation and integration are straightforward thanks to the radio's built in GPS receiver and support for a single VHF antenna for VHF, DSC, and AIS functions. The VHF 400 connects seamlessly with compatible Garmin chartplotters through NMEA 2000 and the Garmin BlueNet network, and built in Wi Fi allows configuration, MMSI programming, and software updates through the ActiveCaptain app. With its rugged IPX7 water resistant construction, support for remote stations, external speakers, loudhailer functionality, and dependable 25 watt transmit power, the Garmin Signal VHF 400 is a capable communication solution for serious sailors, anglers, and cruising boaters alike.
