Located at 101° W.L, AMERICOM-4 (AMC-4) was launched in 1999 as SES AMERICOM's fourth A2100 hybrid C-band and Ku-band satellite. The C-band payload is home to national television networks broadcasting to thousands of cable headends. AMC-4's Ku-band transponders serve the direct-to-home, VSAT, business television and broadband Internet market segments. These Ku-band transponders are designed to be switchable between North and South American coverages.
