Marine UHF Transceiver JHS-431

The JHS-431 is a 2 watt UHF intrisincally safe transceiver designed for onboard, ship-to-shore or ship-to-ship communications for ship operation, loading/unloading, rescue operations and mooring. Engineered to meet ATEX standards, the JHS-431 is intrisincally safe and is approved for use when transporting, loading or unloading flammable, dangerous materials. The advanced, structurally sound casing and design ensure its safe use in conditions where safe communications is fundamental. The JHS-431 is a one piece, sealed casing design and has outstanding protection against dust and water that is equivalent to military grade IP67. The unit can withstand submersion in 1 meter depth of water for up to 30 minutes and has dust-tight construction that prevents the ingress of dust, ensuring usage in the most severe conditions. The JHS-431 delivers a loud 350mW audio output with the built-in Bridge-Tied Load (BTL) amplifier. Improved bass characteristics improves the audio quality.
