Marine AIS Transponder HA102

The Ruth's sister HA102 is a Class B AIS transponder designed for marine vessels requiring both receive and transmit capability. It supports dual-channel operation and CSTDMA function for automatic slot allocation. This unit suits recreational and small commercial craft needing to broadcast their position and track nearby traffic. It is not intended for vessels mandated to carry Class A equipment or for installations requiring integrated display functions.

Dual Channel CSTDMA Operation

The HA102 handles simultaneous reception on two VHF channels and transmits using Carrier Sense TDMA to avoid slot collisions. It comfortably manages routine position reporting and collision avoidance data exchange in moderate traffic areas. The system reaches its limit in very high-density waterways where slot contention exceeds CSTDMA resolution or where faster update rates than Class B allows are required by regulation.

Questions about this item

Can the HA102 integrate with my current marine electronics using its dual-channel CSTDMA function?

The HA102 uses dual-channel CSTDMA operation to exchange AIS data on standard VHF marine channels, allowing it to work alongside existing Class A and Class B transponders without additional hardware.

How do I verify the HA102 is transmitting correctly after installation?

The HA102 will appear on nearby AIS displays and chartplotters as a Class B target with your MMSI once its dual-channel receiver and transmitter are actively processing VHF AIS messages.
