6. Antenna Alignment
AirLive AirMax5N/ESD User’s Manual
60
It is important to align your antenna correctly with the remote device to get the best signal
and performance. The AirMax5N is equipped with a 16dBi antenna. There is a connector
for external antenna if more distance or different angle coverage is required. In this chapter,
we will first explain the design and function of the built-in antenna.
We will provide instructions on the two alignment methods later in this chapter. It is
recommended that you read through 4.2.12 on how to change antenna settings, and 4.2.20
about the RSSI LED Threshold before reading this chapter.
6.1 About AirMax5N’s Antenna
The AirMax’s built-in antenna has the following characteristics:
 Gain: 16dBi
 Type: Patch Antenna
 Vertical Coverage Angle: 20 degree forward
 Horizontal Coverage Angle: 30 degree forward
 External Antenna Connector: R-SMA
6.1.1 Mounting Adjustment
The degree you can adjust the AirMax5N’s antenna depends on what mounting kit you use.
Using the standard strap mount allows you to rotate the CPE in the horizontal plane only. As
long as 2 wireless devices are at about the same elevation, this adjustment is already
enough.
6.2 Preparation before Installation
The antenna alignment is for small adjustment only, you should not use it find remote AP.
The correct way is to use a Graphic Information System (GIS) program such as “Google
Earth” to find the locations of the installation site and the nearest AP/Bridge. Then measure
the approximate direction and angle. It will also help to bring a pair of hi power binocular for
sight survey.
