  • Capturing Iridium voice and data signals to bring them inside a building .
  • Situations where required antenna cable length is greater than 40ft. (12m).
  • Built for use in fixed-site installations.
  • Top-Mounting on a 1″ diameter pipe/pole.
The Iridium antenna comes with the following:

An External Iridium Active Antenna for Building Installations

This is an active antenna, which means that it is directly powered from a power supply (rather than an Iridium phone or docking station) and allows much thinner and cheaper antenna cable to run up to 300 ft (100m), which would never be possible with a passive Iridium Antenna such as the RST710 or RST720.

Using thinner types of antenna cable makes the installation process much easier and less expensive.

Mounting Options

The RST740 Iridium active antenna is omni-directional, meaning it can acquire a signal from all directions. It must be top-mounted to a 1″ diameter pipe using the included pipe-mounting assembly.

For best performance, make sure this antenna has an unobstructed view of the sky.

Compatible With All Iridium Products

This antenna is fitted with an TNC male connector and will work with all Iridium products to capture Iridium voice and data signals.
