ICOM SAT100 PTT Handheld Satellite 2-Way Radio


Icom IC-SAT100 Handheld Iridium PTT Radio

Unlimited Calling via Satellite for a low flat monthly rate

Seasonal and Annual contract terms available

Note:  To start service, you will need at least three (3) Icom Ic-SAT100 (or) Iridium Extreme PTT devices (or) a combination of the two.


The IC-SAT100 provides a true Land Mobile Radio experience with an IP67-rated durable housing, large front-ported speaker for loud audio, a top mounted on/off volume selector, talkgroup selector for “no-look” operation, and a field replaceable antenna. Icom offers a large portfolio of Land Mobile Radio accessories for the radio to enhance the customers communication requirements.

The IC-SAT100 operates exclusively on Iridium Push-To-Talk services, and is compatible with the full portfolio of Iridium and Iridium Partner PTT products for seamless, global push-to-talk capabilities. Icom also offers the VE-PG4, a RoIP router to interconnect and manage latency of other radio technologies into a seamless communication.

Using the VE-PG4 RoIP router, you can interconnect your satellite PTT radio with marine or land mobile VHF, PTT LTE Radios, WiFi LTE Radios, and PBX telephone systems.   Using a combination of WiFi radios, the RoIP router, and a SAT100, for example can allow for remote command centers in areas without cellular coverage to have local WiFi radio communications and a remote satellite radio link to other command centers.


One-to-Many Global Communications with a Push of a Button

Icom’s IC-SAT100 allows users around the world to communicate with a group of PTT radios at the push of a button. To do this, the IC-SAT100 utilizes Iridium® satellite network covering the earth including both poles providing wide area global communication anywhere on the planet.


Icom’s IC-SAT100 radios uses SATELLITE PTT (Push-To-Talk), which is a two-way radio system using the Iridium® satellite network. This network allows you to use the IC-SAT100 in remote, isolated areas without mobile phones or landline network infrastructure or if terrestrial network infrastructure is rendered unusable by human or natural disasters.

One-to-Many Communications

Satellite PTT

Unlike satellite phones, IC-SAT100 users can immediately start talking to all the radios in the same talkgroup, with just a push of the transmit (PTT) button.

Real-Time Low-Latency Communication

Real-time low-latency communication

Using 66 Low Earth Orbit (LEO) Iridium® satellites, the IC-SAT100 provides low-latency communication, and broader, more reliable network coverage, compared to Geosynchronous Equatorial Orbit (GEO) satellites.

Satellite PTT Airtime

PTT Airtime Plans

  • All PTT Airtime plans include unlimited airtime for a flat monthly fee.
  • At least 3 PTT Units are required to activate service (Iridium Extreme PPT and Icom SAT100 units supported)
  • 3 month and 12 month contracts available
  • Devices are added to talkgroups (up to 15 talkgroups per device are supported)
  • There is no limit to the number of devices that can be in one talkgroup
  • One-to-Many Communications, all devices operating in a talkgroup hear all communications for that talkgroup (similar to VHF/UHF Radio)
  • Each device can be on it’s own contract and airtime plan, e.g. you can have some year-round devices, and additional seasonal devices, all sharing the same talkgroups.

Airtime plan details below.. Do not hesitate to call or email Sea-Tech Systems with any questions.  We can help you select the best devices, talkgroups, and device plans for your particular needs.

PTT Service Requires two (2) components.

Requirement One:  Activate at least one (1) talkgroup.  Talkgroups come in 5 different sizes from small (100,000 sq km area maximum) up through Jumbo (2,250,000 sq km area maximum)

Sea-Tech currently offers the small and medium talkgroups for free.  Large, Extra Large, and Jumbo require a monthly fee (single fee per talkgroup per month) which is in addition to the per-device fees below.  A device must be assigned to a talkgroup to communicate with other devices in that talkgroup AND the device must be physically within the defined area of the talkgroup (this is managed with the devices built-in GPS receiver).   Talkgroups can be changed at any time and changes take effect within minutes.

  • Small Talk Group: (100,000 square km)
    • Monthly Talkgroup Access Fee : $150/Mo  $0/Mo
  • Medium Talk Group: (300,000 square km)
    • Monthly Talkgroup Access Fee : $250/Mo  $0/Mo
  • Large Talk Group: (750,000 square km)
    • Monthly Talkgroup Access Fee : $450/Mo
  • Extra Large Talk Group: (1,500,000 square km)
    • Monthly Talkgroup Access Fee : $1050/Mo
  • Jumbo Talk Group: (2,250,000 square km)
    • Monthly Talkgroup Access Fee : $2400/Mo

Note: You can create any number of talkgroups of each size, and assign devices to multiple talkgroups.  You will be billed each month for each talkgroup that has been created, regardless of how many devices are assigned to the talkgroup (including 0 devices).   A single device can only be added to 15 talkgroups, and when a user talks, that communication is sent only to the talkgroup that the user has selected on their dervice at that time.

You can also break up a single talkgroup into up to 10 areas.  The total square area of all the areas cannot exceed the maximum sq area of the talkgroup.  For example, with a single small talkgroup, you can create 4 circles of 10,000 sq km, and 4 squares of 10,000 sq km, plus a rectangle of 20,000 sq km, each in a completely different geographical location, and any devices in one of the 9 areas will be able to communicate with the other devices in that talkgroup, within on of the 9 areas.

Requirement Two:  Activate at least three (3) PTT devices.  Device plans come in two versions, seasonal and annual.

3 Month Device Contracts (Perfect for Seasonal Use)

  • Activate your Satellite PTT device for 3 or more months to cover a season (ie: fishing season, etc) then deactivate for off-season.  Reactivate for each season as needed.
    • $50 Activation Fee (per activation event, not per-device)
    • $109.99/Month/Device
    • $225 Early Termination Fee (if deactivated before the end of the 3 month contract)

12 Month Device Contracts (Lower cost per month for year-round use)

  • If you need to have access to your PTT services nearly year round, 12 month contracts provide lower monthly access costs.
    • $50 Activation Fee (per activation event, not per-device)
    • $67.99/Month/Device
    • $450 Early Termination Fee (if deactivated before the end of the 12 month contract)
