You can find feeds on different satellites. Once you get to know how it works, you will find them easily, as they normally use more or less the same frequency ranges for each satellite. To know which satellites you can receive in your region and what the required dish size is, you can consult the footprints of the satellites. Head over to
LyngSat and play with this site. They offer footprints for most satellites.
The best tool for finding feeds is a spectrum analyser. This is implemented quite cheaply by the CrazyScan compatible cards and USB devices.
However, most feeds are used for uncommented B-class sports events or news feeds. It is INTERESTING to see but not something I would watch from start to end. Top-Class events are broadcast in encrypted form. Most satellite modulators and professional receivers (IRD) will support BISS encryption. This only requires to input a 16 digit key on both ends, but is enough for people like us to not be able to decode the stream.
As you may getting the hint, this is a hobby like any other: the more you get involved, the more money you spend to achieve more.
In this case:
- Professional satellite field meter to fine tune the dish and to detect uncommon transmissions (=feeds)
- Bigger dish: the bigger, the more exotic satellites you can receive. Big goes from 1m Offset to 8m Prime Focus. Yes, some people on this forum use dishes that big!
- Ku band is the norm, but there is C band and Ka band, also. Interesting stuff is happening in the Ka band, but one single Ka band LNB can cost 1000 Euro and more and only covers part of the Ka band (you will need several different Ka band LNB's to cover the whole Ka band)
- Professional receivers (IRD): they come in a 19" rack format and support less common modulations and encoding
- Two axis motor for prime focus dish: get the maximum reception by rotating the dish while simultaneously fine tuning the elevation
- Motorized feed: allows automatic exchange of LNB (C, Ku, Ka) and/or rotation of LNB for correct polarisation
- ...
So, while you can start your hobby with little money, it can grow almost endlessly!
Do your reading in this forum and other forums. It is an intersting field, for sure.
