The Model 50400S is a 400 MHz “smart” antenna. This antenna has a special chip in it that will work with the SIR-30 and SI-4000 control units (not the SIR-3000). This chip will identify the antenna to the SIR-system control unit so that the controller will be able to automatically load up the correct default settings. The 50400S will function with all GSSI’s previous controllers, but the user will need to manually set the collection parameters on the SIR-system.
