The Antenna Pattern for Radio Waves

The power of the wireless signal is most strong on the horizontal plane of the
Omni-Directional Antenna. The peak gain of this antenna is 9dBi. The diagrams
below show the antenna pattern of the 9dBi Omni-Directional Antenna on the
horizontal and vertical planes.
