The radiation pattern is the direction or direction'''s''' where the signal will be emitted (or received).
The radiation pattern is the direction or direction{{underline|'''s'''}} where the signal will be emitted (or received).
So for a given transmission power, a directional antenna would send the signal further than an hemisphere antenna. Indeed, directional antenna would concentrate all the power is one direction where as hemisphere antenna would spread the same power all around.

The Yagi antenna does support several radiation pattern but "Yagi" is often used in place of "Directional Yagi".
