First of all, welcome to the group.
Currently, Outernet is broadcasting on the Ku-band only to North America. Other satellite beams are in the works, but there is no broadcast to South America right now.
The required hardware, a Dreamcatcher 3.03 and Maverick MK1-PLL LNB are available right here.
Stay tuned. The service works well for me in the Seattle, WA metro with a little adjustment to the antenna. In areas where there’s good coverage, the LNB and the board alone are enough to pick up the signal. I’m in a fringe area with some special circumstances. I added a small cone to get a little antenna gain.
As soon as service is available to Brazil, I’m sure you will know.
It might be useful for @Syed to know how many people from Central and South America are interested in Outernet.
