SI-TEX - MDA5H Class B AIS - No Wifi

Advanced Class B+ AIS Transceiver for Reliable Marine Navigation

The Sitex MDA-5H Class B+ SOTDMA AIS Transceiver is one of the most advanced AIS modules available, offering high-performance vessel tracking and seamless integration with marine systems. Designed for professional and recreational mariners alike, this AIS transceiver ensures superior visibility on AIS networks, even in highly congested waterways. With 5-watt transmission power, it provides extended range and priority broadcasting over traditional Class B units.

The unit is fully waterproof (IPX7 certified) and features an integrated zero-loss VHF antenna splitter, eliminating the need for a second antenna. With multiple connectivity options, including NMEA-0183, NMEA-2000, and USB, it easily interfaces with onboard navigation and communication systems. A built-in GPS & GLONASS receiver ensures accurate positioning, while dual receivers decode all DSC & AIS messages, including MOB (Man Overboard) and SART (Search and Rescue Transponder) alerts.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
