Standard Horizon HX400IS 5W Intrinsically Safe Handheld VHF Radio

Manufacturer

Standard Horizon

<h3>Standard Horizon: The Gold Standard in Marine Communication</h3><p><strong>Standard Horizon</strong> has earned its place as one of the most trusted names in marine electronics over more than five decades of innovation. <a href="/7587-standard-horizon">A subsidiary of Yaesu Musen Co., Ltd.</a> — a Japanese company with roots in commercial and amateur radio manufacturing dating back to 1959 — Standard Horizon combines deep radio engineering expertise with a laser focus on the demands of the open water. The result is a product lineup that recreational boaters, commercial mariners, and government agencies around the world have come to rely on for safety-critical communication.</p><h3>Built for the Water, Trusted on Every Voyage</h3><p>At the heart of the Standard Horizon lineup are its renowned <a href="/7587-standard-horizon-vhf-radios-handheld-202719">handheld VHF radios</a>, which have made the brand the leading manufacturer of VHF marine radios in the United States. These compact, rugged transceivers are engineered to endure the harshest marine conditions — think salt spray, accidental submersion, and the punishing vibration of a fast-moving hull. Many models meet or exceed IPX8 waterproofing standards, meaning they can survive submersion well beyond the typical splash or rain event you might encounter on the water.</p><p>Standard Horizon&apos;s <a href="/7587-standard-horizon-vhf-radios-handheld-201143">VHF radio</a> product range spans everything from ultra-compact units — some barely larger than a deck of playing cards — to full-featured models packed with GPS receivers, Digital Selective Calling (DSC), Bluetooth connectivity, NOAA weather alert channels, and FM broadcast reception. DSC capability is especially important for safety: it enables mariners to transmit an automated distress signal with precise GPS coordinates at the press of a single button, a feature that can be life-saving in an emergency.</p><h3>Why Standard Horizon Stands Apart</h3><p>The brand&apos;s commitment to engineering excellence has not gone unnoticed in the industry. Standard Horizon VHF radios have earned the prestigious NMEA (National Marine Electronics Association) award for design and engineering excellence an exceptional number of times, a testament to the brand&apos;s sustained focus on quality. Features like rapid charging, floating designs that activate a strobe light on water contact, noise-cancelling microphones, and programmable channel scanning reflect a thoughtful approach to the real-world needs of boaters — not just a checklist of specs.</p><p>Beyond radios, Standard Horizon also produces GPS chartplotters, sonar transducers, loud hailers, and a full ecosystem of accessories including remote speaker microphones, antennas, battery packs, and mounting hardware. Whether you&apos;re outfitting a weekend fishing boat, a coastal cruiser, or a commercial vessel, Standard Horizon offers the communication and navigation tools to keep you safe, informed, and connected at sea.</p><h3>A Legacy of Marine Safety</h3><p>What sets Standard Horizon apart from the competition is not just the technology inside each unit, but the philosophy behind it: every product is built as if lives depend on it — because sometimes they do. With corrosion-resistant hardware, marine-grade connectors, and robust waterproof housings, these radios are designed to perform reliably when conditions deteriorate and dependable communication matters most. For mariners who take safety seriously, Standard Horizon remains the benchmark.</p>
