Beam RST740 Iridium Active Antenna

Powered External Antenna for Long Cable Run Iridium Installations

Part Number: RST740

The Beam RST740 is a high-performance active (powered) Iridium antenna designed for land and maritime applications where long cable runs are required between the antenna and terminal. By amplifying the signal at the antenna, the RST740 enables cable runs of up to 100 metres (300 ft), which is not achievable with passive antennas.

Supplied with a power breakout (bias) box, the RST740 ensures stable signal performance and efficient power delivery, making it ideal for professional satellite communication deployments in demanding environments.
