Footprints
The satellite footprint is a map showing a satellite’s fieldstrength or EIRP
(Effective Isotopic Radiated Power). It's not a real unit, but more a practical
model you can use when you graphically view the radiated area.
Every satellite has it's own footprint, and by consulting the footprints and the
conversion table you can estimate the antenna size needed.
One satellite can transmit several beams, where every beam has it's own
footprint and content regarding channels and service providers.
For updated information regarding footprints, frequencies, service providers etc.
we recommend you to consult websites such as www.lyngsat.com,
www.satbeam.com or www.kingofsat.net.
Below you can see a few typical footprints Anik F1R (W107,3), Astra 1H (E28,2)
and NSS6 (E95,0)
