I am no expert in cell tower. But I looked at google satellite image and it looks like Egbe is a small town and a cell tower should cover it (but check with the expert ok?).
If I am the decision maker, I will put it somewhere in the cheapest block of land you can find near the centre of the town for good coverage. Also put it near road for good access for maintenance.
Don't put it near the schools (I saw 2 school) or the church. Although there is no scientific evidence for cell tower causing cancer, people still get superstitious. You don't want the community, especially the children's parents, blame you and sue the government for compensation for cancer which is not related to your cell tower.
Thanks for the very useful piece of advice.
