Installation Procedures
Follow these steps to install an external antenna and connect it to the
Access Point 420.
Access Point 420.
1. Plan the Installation
■
Pigtail Cables
- Use the coax pigtail cable included with the antenna to
connect to the access point. Because most pigtail cables are a relatively
short length (83 cm or 33 inches), be sure to find a suitable mounting
position for the antenna that is not too far from the access point. If an
extension cable is required, please contact a professional installer who is
trained in RF installation and knowledgeable in the local regulations.

C a u t i o n
Never mount the access point outdoors to be near an external antenna. The
access point must always be installed indoors.

Installation Location
- Plan the antenna’s position and orientation.
Consider these points:
•
Use the antenna’s mounting bracket or other hardware, if included.
•
For optimum performance, mount antennas as high as possible above
any obstructions, and away from any signal absorbing or reflecting
structures (such as those containing metal)
any obstructions, and away from any signal absorbing or reflecting
structures (such as those containing metal)
•
Be sure there are no other radio antennas mounted within 2 m (6 ft).
•
Consider the antenna’s radio coverage pattern so that it can properly
cover the intended service area.

■
Omnidirectional Antennas
- Consider these factors when selecting a
location for these antennas:
•
Always mount the antenna in a vertical orientation so that the radio
coverage pattern fills the intended horizontal space.

•
For optimum coverage, mount the antenna at the center of the area
with a line-of-sight path to all points within the area.

•
Avoid mounting next to or near building support columns or other
obstructions that may cause reduced signal or null zones in parts of
the coverage area.
