The only "not too expensive good antenna" is a LNB.  The problem is that unless you are willing to spend a horrendous amount of money you cannot get a receiver which will operate at 3.6GHz.  To use the existing cheap dongles, which by the way are perfect for the job, you will need a down-converter, which is basically what the LNB is.  You cannot use the LNB or adequately receive C-Band data without a dish. I believe that In UK and D a cheap TV dish may be adequate at least for 1200bps channels.  I strongly advise that you take note of the recommendations from Paul and Patrick, who have experience in this area.

I understand that the data I would like to receive is Inmarsat C data (data communication).
As I am here more or less in the center of Germany this data is provided currently by AOR-E at 15.5W.
As I have found out to my dismay my balcony garnished with an array of sat dishes does not offer me a free view of this satellite - its path
for my balcony "Sport"  is too far to the west, i.e. on the other side of my terrace house !
A lot of Money wasted so far.
I now look for a not too expensive good antenna - be it active or passive - allowing bracket mounting on my already installed roof mast.
Wont be easy to find I guess considering that from there to my RX - just a Dongle - Funcube and the like - I need some 20m coax cable.
Here - in case of choosing an active antenna I again face the Problem of inserting a separate Bias T !
The "elegant" solution would be a Passive inmarsat antenna providing good data despite my cable length of 20m.
Do you know or already use such a passive antenna - if so please provide details !
To round it off and increase my bad luck I discover in a distance of some 150 the mast of a mobile phone base station !!
