Footprint
The size of the satellite dish required to receive transmissions from ASTRA satellites depends on the transponder polarization and the location of the dish. ASTRA 1E uses two polarizations, resulting in a number of footprints for each satellite. In the respective 60cm and 85cm zones, reception with DUOLNB II(60cm) and DUOLNB I(85cm) is possible.
FSS: 10.70-10.95GHz, 26MHz per channel
BSS: 11.70-12.10GHz, 33MHz per channel
