The External Directional Antenna

In large, open areas, the external directional antenna can
show you the direction of a signal source more precisely
than the omnidirectional antenna in the tester.
In areas that have many rooms, for example in
schools and hospitals, use the internal
omnidirectional antenna to locate access points.
To use the external antenna
Connect the antenna to the antenna jack on the rear of
1
the tester. The screen shows the antenna icon ( ) when
you connect the antenna. The tester uses only the
external antenna when the antenna is connected.
When the external antenna is connected, the tester
will not transmit, so it will not connect to a network
or access point.
Divide the area into four sections, as shown in Figure
2
26. Go to the center of the area.

Use these guidelines when you use the external antenna:
• Hold the antenna at a constant height. You can get
more stable measurements if you hold the antenna
above cubicle walls.
• When you point the antenna in different directions, do
not move your arm. Hold the tester and antenna in one
position while you turn your body.
