It runs on a 12 V DC system (13.6 V nominal), transmits at 25 W or 1 W, and is rated IPX7 for wet-weather use at the helm.\u003c\/p\u003e\u003cp\u003eAIS targets can be viewed on the radio screen or shared to a compatible multifunction display for overlay via NMEA 2000 or NMEA 0183. The internal GPS is rated at under 10 m horizontal accuracy with a 1-second typical update interval, and the chassis measures 201.2 mm wide x 97.8 mm high x 163.3 mm deep (7.92 in x 3.85 in x 6.43 in) without the bracket.\u003c\/p\u003e\u003cp\u003eThis is a solid fit for boaters who want one radio to handle voice, DSC distress calling, and AIS transmit and receive, with the option to add wireless handsets for coverage beyond the main helm.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eClass D DSC VHF with dual receiver for dedicated Channel 70 handling\u003c\/li\u003e\n\u003cli\u003eVHF transmit power: 25 W high power or 1 W low power\u003c\/li\u003e\n\u003cli\u003eIntegrated Class B AIS transceiver for AIS transmit and receive\u003c\/li\u003e\n\u003cli\u003eInternal GPS receiver rated under 10 m accuracy with 1-second typical position updates\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 and NMEA 0183 connectivity for sharing position, DSC data, and AIS information with compatible electronics\u003c\/li\u003e\n\u003cli\u003eRemovable fist mic with front or rear connection option for cleaner installs and flexible mounting locations\u003c\/li\u003e\n\u003cli\u003eSupports up to two wireless handsets and on-board intercom functionality (up to 80 m line-of-sight base-to-handset range)\u003c\/li\u003e\n\u003cli\u003eConnections for optional hailer output (30 W at 4 ohms) and an external speaker (minimum 4 W at 4 ohms)\u003c\/li\u003e\n\u003cli\u003e12 V DC system with up to 6 A current draw at 25 W transmit, and an 8 A replacement fuse specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in multiple configurations based on whether a GPS-500 antenna is included.\u003c\/p\u003e\u003cp\u003eAll variants are the RS40-B fixed-mount VHF with Class B AIS and an internal GPS receiver. The difference is the GPS-500 antenna bundle option.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e000-14473-001: GPS-500 antenna: No. The radio uses its internal GPS receiver for position data, which keeps the install straightforward when the mounting location has good sky view.\u003c\/li\u003e\n\u003cli\u003e000-14818-001: GPS-500 antenna: Yes. This adds the GPS-500 external GPS antenna, which can help when the radio is mounted under a hardtop, inside a console, or anywhere satellite reception is reduced.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and mounting\u003c\/h6\u003e\u003cp\u003eThe RS40-B supports bracket or flush mounting, and it helps to plan for 163.3 mm (6.43 in) of behind-panel depth for the base unit without the bracket. Keep the radio at least 0.5 m (1.5 ft) from the compass, and choose a location where the display is readable and the microphone can be reached quickly in rough water.\u003c\/p\u003e\u003cp\u003eThe removable fist mic can be plugged into the front or the rear connection, which makes it easier to hide cable runs or mount the base unit overhead while keeping the mic down at the dash.\u003c\/p\u003e\u003ch6\u003eElectrical and antenna setup\u003c\/h6\u003e\u003cp\u003ePower is intended for a 12 V DC battery system, with low-voltage alert around 10.5 V and over-voltage protection above 15.8 V. Current draw is rated up to 6 A at 25 W transmit, so wiring and circuit protection should be sized for a fixed-mount VHF installation.\u003c\/p\u003e\u003cp\u003eFor RF connections, the unit uses SO-239 antenna connectors for both the VHF antenna and the AIS antenna, plus an SMA connector for a GPS antenna. AIS transmit and receive performance depends on proper antenna installation and separation, so plan your antenna layout early, especially on smaller boats with limited mounting points.\u003c\/p\u003e\u003ch6\u003eNetwork and navigation integration\u003c\/h6\u003e\u003cp\u003eNMEA 2000 and NMEA 0183 connections let the RS40-B share AIS and position-related data with compatible displays and onboard systems. If you run a Simrad network at the helm, the backlight can be synchronized over NMEA 2000 so the radio display tracks with the rest of your electronics at night.\u003c\/p\u003e","brand":"Simrad","offers":[{"title":"No","offer_id":52270720090293,"sku":"QBP266929-V1","price":1271.0,"currency_code":"USD","in_stock":false},{"title":"Yes","offer_id":52270720123061,"sku":"QBP266929-V2","price":1377.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1303661_qbp266929.jpg?v=1771550614","url":"https:\/\/www.qualityboatparts.com\/products\/qbp266929","provider":"Quality Boat Parts","version":"1.0","type":"link"}
