In LTE, the antennas have a fairly significant downward angle since every cell uses the same set of channels as every other cell. Before LTE, there would be a frequency reuse pattern, so another cell a few miles away would be using the same spectrum. So even then they are aimed somewhat down rather than at the horizon, as you said. But with LTE it's much more significant.
