Installing the 7782 Access Point in the Field
Mounting External Antennas (7782-E Only)
Mounting and Connecting 5GHz and 2.4GHz External
Antennas
You can connect up to three 5GHz external antennas and/or up to three 2.4GHz external
antennas to the standard N-type female connectors on the 7782-E AP.
WARNING: Only trained and qualified installers should be allowed to install, replace, or
service this equipment.
The professional installer is responsible for the proper installation and configuration of this
AP. The AP installation must comply with local regulatory requirements, especially with
those regulating operation near military and/or weather radar systems.
NOTE: Allowable antenna types and antenna gains may be limited by local regulatory
requirements.
1. If the AP is powered, then disconnect the AP from the power source.
WARNING: Before connecting the antennas to the 7782-E, make sure that you disconnect
the AP from the power source.
2. Refer to Table 6 and determine which 2.4GHz and which 5GHz connectors to use.
3. Unscrew the metal caps that protect the antenna connectors. Place the metal caps in
a safe place, in case you need them later.
4. Connect the antennas to the standard N-type female antenna connectors on the
7782-E AP. Use a torque wrench to tighten the connectors to 1.58 N.m (14 in-lbs).
5. If the antennas come with RF coaxial cables (for example, a patch antenna), then do
the following:
a. Physically mount the antenna at your desired location, preferably on the same
mounting structure as the AP.
NOTE: Mount the external antennas at least 20cm (7.9”) away from each other and other
antennas.
b. Connect the 5GHz RF coaxial cables to up to three 5GHz standard N-type female
connectors on the AP. Use a torque wrench to tighten the connectors to 1.58 N.m
(14 in-lbs).
c. Connect the 2.4GHz RF coaxial cables to up to three 2.4GHz standard N-type
female connectors on the AP. Use a torque wrench to tighten the connectors to
1.58 N.m (14 in-lbs).
