ASTRA 4A
ASTRA 4A* is located at 5° East, ASTRA's position for Direct-to-Home broadcasting to sub-Saharan Africa. ASTRA 4A provides DTH coverage to multiple African markets with a dedicated Ku-band beam from a single orbital position - which eliminates the need for dual-illumination from separate beams. ASTRA 4A offers uplink and downlink within the African footprint, and also inter-connectivity between Africa and Europe: DTH broadcasting out of Europe is available without the need for expensive fibre links.
