Sky ConnectTM I & II IridiumTM Satellite Telephone Terminals

SkyConnect IIWhen you absolutely need a dialtone during a disaster response or in the middle of nowhere, a satellite telephone is often the only solution. However, most satellite phones are handheld, single line, must be used outdoors in the weather, and cannot be connected to other telephone equipment or an external antenna.

Our rugged Iridium Sky Connect portable or installable satellite telephone terminals easily solve those problems.

The Sky Connect single or dual line satellite  telephone terminal may be connected to our portable PBX telephone systems, any permanently installed PBX system, or to any conventional single line telephone with a standard RJ-11 telephone cord.

2400 baud data communication via the satellite is possible using the terminal’s USB data port. It is quick and easy to setup with little training. With data compression software, speeds are available up to 10Kbps, adequate for text-only email. 

The external antenna can be placed out in the open or on a rooftop for a clear, unobstructed view of the sky. This means fewer dropped or lost calls and greater signal reliability, as well as the ability to make your calls from a protected indoor environment.

The terminal is contained in its own rugged portable enclosure with protective clamp-on covers. The  antenna, power and data cables, and system manuals are all carried in a matching accessory case. Also included is a portable 6′ folding antenna tripod in a nylon carry bag (shown at right with antenna). Optional orange nylon sandbags (empty) are available for weighting the tripod legs in high wind conditions.



SkyConnect antenna and tripodPermanent wall, bulkhead, or rack-mount installation configurations are available for buildings or vehicles. Use for telephone backup service when regular telephone service is disrupted, or for mobile command posts.

Satellite Telephone backup for your office

Sky Connect Indoors

Sky Connect Indoors - Iridium Sat Phone

(Mobile and Marine versions available)

When the phones go out and you still need to communicate, the most reliable option is satellite telephone. However, most sat phones are hand-held and require the user to be outdoors – in the weather – and require some degree of training to use.

The Sky Connect IndoorsTM single-line satellite telephone solves those problems.

The Sky Connect Indoors satellite telephone and data terminal can be permanently installed in your office or mobile command center and connected to either a conventional phone or directly to a designated trunk port on your office PBX telephone system. When you need to make a sat phone call, simply dial the access code for that trunk port, and you will have the satellite dial tone!

A local control handset is available for connection to the terminal itself, and can be remoted to another part of the building if necessary. The handset supports voice calls and SMS messages, as well as access to other features. 

The Sky Connect Indoor terminal can also save money by allowing lower-cost Iridium to Iridium calls if you have other mobile or portable units in the field.

Low speed data service is also available at rates from 2400 to 10kbps, adequate for text-only email, via an RS-232 port, up to 50′ from the terminal. Longer distances (3000′ or more) can be achieved using two RS-485 converters. Data service requires an additional monthly fee.

The Sky Connect Indoor terminal can be powered with 120vac or 10-32vdc, as needed, and draws very little power (1 amp at 12vdc while transmitting). For maximum reliability, we offer a 12 volt power supply with battery backup. The radio can be installed remotely from other telephone equipment in order to keep the antenna cable as short as possible. Custom weatherproof housings are available for roof-top installation upon request.

An internal SIM card is used to activate the phone and identify it to the system. An external SIM card reader is available for multiple users to bill calls to their own accounts.

Also perfect for remote sites without regular telephone service. Kits are available for vehicle or marine intallation – call for details.
