The first thing we have to do is to mount our parabolic antenna;
After we need to pointing it out (searching right degrees from some magazine): degrees are always intended from south to east or to west for horizontal one and from ground to satellite line for vertical one. Classical pointing tools is the compass.
How can we see if we are right oriented?
After decided a right range of angles, we have to adjust it measuring power level. For such a thing we can
You can also install a double feed system (some vendors sell a complete kit with standard distance to receive, for example, Astra (19.2 SE) with Eutelsat (16 SE) or with HotBird (13 SE).
For mounting it you have to consider, in addition, that satellite is at the opposite side of the converter, like in figure:
SAT1 SAT2 \ / \ / \ C1 C2 / \ \ \ / / / \ \ / \ / / \____\ /___\ /_____/ Top View C1 receives from SAT2 C2 receives from SAT1
Also, with 2 focus, you would use a diseq.
Once we got analog signal we have to adjust our receiver to right frequency, PID, speed rate and so on.
I report here an example of configuration, for EON (EuropeOnLine), transponder 114 on Astra satellite (19.2 SE)
Frequency: 12640 MHz
Polarization: V (Vertical)
Symbol Rate: 22000 KS/s
We also need another info: what MAC address to assign to our DVB card.
Again, for EON you can see Appendix A to calculate MAC address from dynamic IP address.
Obviously you need login and password to use ISP service.
