Buying a 'yagi satellite' in E. Malaysia (Sabah, Borneo)

Versione lingua:

I live in Sandakan, Sabah, E. Malaysia, and the area we've just moved to has to line for internet. I have a type of thumb-drive that gives me very limited access to the internet (can't do any email from our home, the signal is too weak) - but a friend just advised I look into buying a 'yagi satellite' so I can actually have full access to the internet with the device we're paying monthly on. If you know of any place in all of Sabah (particularly in Sandakan) that sells something like this, I'd really appreciate knowing about it. TQ!!
