Iridium Beam Active Antenna (RST740)

The Active / Powered Iridium antenna RST740 is designed for Land and Maritime applications specifically for use where long cable runs are required to reach between the required antenna location and the terminal.

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.
