Satellite vsat communication is split up in to four radio frequency rf bands that commercial communication and military satellites operate within.
Satellite communication uplink frequency.
These different frequency bands have separate uplink tx and downlink rx frequencies require different rf components lnb and buc and are suited to different applications.
In europe ku band downlink is used from 10 7 ghz to 12 75 ghz for direct broadcast satellite services such as astra.
3 the second type downlink jamming disrupts transmissions sent from the satellite to ground based or airborne receivers using rf signals that mimic the frequency of the downlink signal.
An rf signal of the same frequency as the targeted uplink signal is transmitted to the satellite aiming to limit the satellite transponder from differentiating between the jamming signal and the actual signal.
