UHF Satcom Terminals

With our RT-18XX family of UHF Satcom Terminals, you can choose a Satcom terminal that best matches your requirements. The four terminals use the same modules (cards), so you keep spares to the minimum. The card set for one Satcom channel includes an upconverter, downconverter, modem and input/output modules. The difference in the terminals is twofold; the application and chassis type.

Model	Application	Chassis
RT-1828	Shore stations or other benign environments	9U high; one to four UHF Satcom channels
RT-1829	Shipboard	Similar to the RT-1828, but ruggedized with shock mounts, module stiffeners, and conformal coated cards; meets or exceeds the shock, vibe, and other DoD environmental requirements
RT-1830(P)/G	Shore stations or other benign environments	3U high terminal; one UHF Satcom channel
RT-1831	Airborne	Similar to the RT-1828, but ruggedized for applications with a one-ATR form factor; one or two UHF Satcom channels
