Installation Procedures
Using an External Antenna
with the Access Point 420
Note that diversity antennas have two pigtail cables. A diversity antenna
includes two internal antenna elements that are identical. Both antenna pigtail
cables must be connected to the access point for correct operation.
Other non-diversity antennas, which have only one pigtail cable, attach to the
access point’s right antenna connector. The access point’s right antenna is the
one on the side closest to the LED indicators. When using a non-diversity
antenna, a 50-ohm terminator (included with the antenna) must be connected
to the access point’s left antenna connector.
To connect pigtail cables to the access point, follow these steps:
1. Disable the access point radio using the web browser interface, CLI, or
SNMP.
2. Remove power to the access point.
3. Remove both of the access point’s antennas by unscrewing them at their
base.
4. For diversity antennas, connect the antenna pigtail cables to the exposed
Reverse SMA connectors on both sides of the access point.
For non-diversity antennas, be sure to connect the single pigtail cable to
the Reverse SMA connector on the access point’s right side. When using
a non-diversity antenna, you must also connect the 50-ohm terminator
(5092-0933), included with the antenna, to the access point’s left-side
Reverse SMA connector.
