AIS Transponder Comparison Table

AIS Transponder Comparison Table | Milltech Marine

Choosing the right AIS transponder depends on more than price.

Vessel type, cruising area, antenna setup, onboard network, Wi-Fi needs, VHF integration and transmit power can all affect which unit makes the most sense for your boat.

This AIS comparison guide is designed to make that process easier. Use the searchable table below to compare Class A, Class B CSTDMA and Class B SOTDMA AIS transponders across key features including transmit power, NMEA 0183, NMEA 2000, USB, Wi-Fi, Bluetooth, integrated splitters, GPS antenna options, IP rating, warranty and online price.

As a general rule, 5W SOTDMA models are a strong choice for busy waterways, faster vessels and offshore use, while 2W CSTDMA models can still be a practical fit for many recreational boats. Units with built-in Wi-Fi are useful for tablets and mobile apps, while models with integrated VHF antenna splitters can simplify installations where a dedicated AIS antenna is not practical.

SO = SOTDMA CS = CSTDMA AIS PWR shown in watts Splitter shares one VHF antenna
