Uni directional or yagi antennas are slightly more advanced than omni antennas. Once installed high on the roof or wall, the directional antenna will pull in signal from 45-90 degrees.
With such a narrow field of concentration, it allows the antenna to reach out farther to pull in signal. So it needs to be pointed at the cell tower.
This doesn’t make it any clearer though.
Maybe because Unidirectional is a more and clearer used name?
