Answer and Explanation:
Omnidirectional antenna are those antennas which receives the signals from multiple directions equally.These are the antennas that cannot  get the signal from a particular direction thus gives the low throughput.
To get high throughput, directional antennas should be installed because they receive the signal from a particular direction only .Thus the signal received from these antenna work for a certain area.Example-Television antenna at homes are directional antennas names as Yagi-uda antennas.
