Some antennas can broadcast signals in all directions, they are called omnidirectional antennas. Other antennas can also broadcast signals in a fine straight line - like a flashlight, they are called directional antennas. Electrical signals with frequencies higher on the spectrum, for example, are shorter and more directional. As they get higher on the spectrum, they behave more like light. These must be focused and thus, require antennas which are shaped like the mirror reflector of a focusing flashlight. This parabolic shape focuses the broad beam (of the bulb or the electrical signal), into a narrow, focused beam. The weaker the received signal the bigger the antenna must be.
