Astra 3A was launched to provide follow-on capacity to replace the DFS-Kopernikus 3 satellite and deliver additional capacity for the Benelux countries and central Europe, to create SES-Astra’s third major European satellite hotspot after Astra 19.2°E and Astra 28.2°E with access to channels at both positions using a single dish fitted with a monoblock Duo LNB.
In March 2007, a new type of monoblock, called the Duo LNB was introduced by CanalDigitaal in the Netherlands for the simultaneous reception of Astra 19.2°E/Astra 23.5°E with a spacing of just 4.3 degrees.
