As Lunsat2 advised. Learn much from lyngat/flysat/satbeams
You are actually targeting the MENA beam from Nilesat which (According to lyngsat) ends up somewhere in Nairobi, so you will need a bigger dish than those you have tried ( 90cm & 180 cm), a decent KU LNB for fringe reception and patience (assuming you are skilled enough), to get the beam here in TZ.
I would have tried to hunt it too but my western side is uphills and obscured by Vegetation and buildings. Think I'll need to take the dish to the roof .Happy hunting bro
