Iridium Beam Active Antenna Features

Where an installation exceeds 20m / 60’ it becomes more cost effective to use an Active/Powered Iridium antenna that allows much thinner and cheaper cable to run up to 100m / 300’ where this would never be possible with a passive Iridium antenna. The Active Antenna RST740 will work on all Beam products and any Iridium devices, however requires an approved Beam Active Antenna cable for use in order to manage the power amplification across the RF line to the antenna.

Key Benefits and Features

• Iridium approved
• High quality enclosure
• Active antenna
• Pole/Mast mounting
• White small size/footprint
• Omni directional
• Supports long cable runs
• Power breakout box included (required 9-32 VDC)
• 12 month repair or replacement warranty
