Designed for in-vehicle and in-building use, the Icom IC-SAT100M Fixed Mount Satellite PTT Radio operates on the Iridium satellite network to provide real-time push-to-talk communications anywhere on the planet. Unlike handheld satellite PTT radios, IC-SAT100M users do not need to stay outside for a clear view of the sky for a stable push-to-talk connection. The IC-SAT100M features a durable housing, large front-ported speaker, powerful 1500 mW audio output for clear communication in noisy environments, an RF unit antenna and built-in Bluetooth capability to support hands-free operation (optional accessory required).

Talkgroups and devices are easily managed via the free Iridium PTT Command Center web application. and with a VE-PG4 RoIP gateway, the IC-SAT100M can interconnect with an IP phone, WLAN, LTE, IDAS digital*, analog transceivers and other communication systems. Please contact us to learn more.

When you choose satellite PTT from Roadpost, along with industry-leading products you get a nimble partner with over 30 years of telecom expertise that is fully committed to your organization’s success.

Note: Icom PTT devices require a monthly PTT service plan to transmit over the Iridium satellite network. PTT service plans feature a flat monthly rate that enables unlimited push-to-talk between users in the same talkgroup. Inquire for details and PTT service pricing.

Installation In-Building or In-Vehicle

The IC-SAT100M PTT radio can be installed inside a building with the antenna unit (with RF unit) extended outside for a clear view of the sky.

Iridium Command Center

In a Building

Using the power over Ethernet (PoE) capability, the main unit supplies power to the antenna unit through the LAN cable. Simply connect the PoE injector/switch to extend the distance between the main unit and the antenna unit.
(A 100 m LAN cable is sold separately).

In a Vehicle

Simply attach the antenna on the roof. The IC-SAT100M PTT radio has Bluetooth® capability to support hands-free operation, while driving. The optional AH-40 antenna provides flexible antenna installation.
