There are three main antenna types:
- Omnidirectional: Omnidirectional antennas provide the most coverage as they transmit over 360 degrees.
- Directional: Directional antennas transmit only in one direction, therefore if the antenna is pointing in the wrong direction, there will be no connection to the wireless network.
- Yagi: Yagi fin is an antenna that can transmit in two directions, therefore it is suitable to be placed between two buildings. A way to remember this for the exam is, Yogi Bear is between two buildings looking for food.
