Retevis RA27 VHF Marine Radio Transceiver 25W IP67 Waterproof GPS NOAA Fixed-Mount Class D DSC Marine Transceiver (USA/INT/CAN)


1:Because RA27 maritime transceivers are mainly used at sea, there is basically no environmental interference, so the maximum communication distance at sea is generally up to 30 nautical miles (about 55Km)
2:If you use it in the city or the suburbs, the maximum distance can reach 5-10 Km


This is a small, exquisite, and easy-to-install marine transceiver, Comply with ITU-R M.493-13 Class D DSC (digital selective calling), supports the latest marine channel standards and DSC protocol standards, features DSC Test Calling and Automatic Position Polling ,There are 11 categories of DSC distress calls, and all DSC calls have 3 security categories, weather channel with weather warning,IP67 submersible waterproof rating ,Separate Receiver for CH70 (Receiving DSC Calls),Dot matrix screen display ,Easy to operate icon and menu system ,Built-in GNSS Module ,Support GPS, GLONAS, SBAS Satellite-based Augmentation System (WAAS/EGNOS/MSAS/GAGAN),And support multiple NMEA format transmission, Very suitable for ocean navigation.
