I've already said that a receiver and LNB will work, but unfortunately we do not have many members located in or around Kenya, you may have to wait until you get there and ask a local installer which satellites are receivable, if you decide to take a receiver, take one with a conditional access slot, something like the Technomate 5400ci+ USB.
This satellite (_http://www.lyngsat.com/intel802.html) is available with a small dish and carries a few Kenyan English language channels.
With a 90cm to 1.2m dish (depends where you are in Kenya) and if you are prepared to subscribe, you should be able to receive Multichice Africa (_http://www.lyngsat.com/packages/mcafrica36.html). The same dish size range for this satellite _http://www.lyngsat.com/intel10.html, in fact this package has a lot of free to air English language channels.
