That is a microwave dish used for point to point communication for eg linking mobile phone base stations. Take it from someone who knows.
Mobile or tv uses same linking. All of these using the "comminication bandwith" so there is no difference around mobile, gps or tv transmission. You can use your telephone for watch tv and you can use your tv for entering internet!
Which of you thinked about this question before i asked: how can you entering internet by using a sattelite tv? it is just gathering waves and have only an antenna. Can't send anything any data.
In remote areas of Australia we have quite a lot of internet connections using satellites, so satellites can be used for two-way data communication.
But you cannot get two-way data communication over an ordinary satellite TV link, that is strictly a one-way link.
If you want to arrange a connection, contact
NBN Satellite (Sky Muster). (see, free ad)
Of course if an internet connection is available by cable, ADSL or mobile data then that is less expensive and has a higher data rate.
Where those are not available (a large part of Australia) satellite internet connections are valuable.
