Can I use the existing Iridium antenna installed in my building with my Data Gateway device?

No, Certus antennas for SkyLink are required. The following are acceptable to use:

• MARUWA (MHL-1621C)
• High-Profile Maxtena (M1621HCT-HP)
• Low-Profile Maxtena (M1621HCT-LP-SM; M1621HCT-LP-MM)
• Sensor Systems (S67-1575-414)
