No, not necessarily. It's a complex problem. I don't want to bore you with it. An antenna cannot cover a large mountainous area; there are some limits. So we would need another antenna or a repeater. I don't have all the answers, but I do know some things.
The program must include access, which should be negotiated by competent people. I don't have that expertise, but others do. I don't want to say something which might be wrong.
