Installing the Antenna
1. Introduction
The Senao access point is designed to perform in a variety of
environments. Implementing the antenna system can greatly improve
coverage and performance. A good communication can only be
achieved with the right antenna. The antenna kits comprise numerous
components, including the antenna, connectors, mounting hardware,
antenna cabling, and in certain product boxes.
2. Type of Antennas
The Senao access point may be bundled with several different
styles of antennas for use in the 2.4GHz range. Each type of antenna
will offer different coverage capabilities. As the gain of an antenna
increases, there is some tradeoff to its coverage area. Usually high gain
antennas offer longer coverage distances, but only in a certain direction.
The radiation patterns below show the coverage areas of the styles of
omni-directional and uni-directional antennas.
◆Omni-Directional Antennas
An omni-directional antenna is designed to provide a 360-degree
radiation pattern. This type of antenna is used when coverage in all
directions from the antenna is required.

Directional antennas have many different styles and shapes. By
redirecting this energy, it has the effect of providing more energy in
one direction, and less energy in all other directions. As the gain of a
directional antenna increases, the angle of radiation usually
decreases, providing a greater coverage distance, but with a reduced
coverage angle.
