with a 90cm it is a challenge to lock on Nile201 which hosts CNN in Nairobi. but you easily lock on Eutel7 at the same position. for a stable 201 you either 180cm prime focus with fujistargold prime focus lnb or 120/130cm offset.....once you stabilize Bbc which is also on 201 at 11766H you will get CNN at 11977V either cracking or OK then stabilize it by adjusting your lnb for 180 pf to 3 o'clock and pulling it out to its maximum (only if fujigold) and you will have achieved on 201. hope this helps. I use 180pf and Fuji lnb on this sat and my my tips on 201 are stable at all times
