AP Placement and Configuration
This chapter provides information for the antenna installer and network manager to determine
where to place the RoamAbout AP and Lightning Protector.
Determining the Location of the AP
The RoamAbout AP connects to a Lightning Protector with a 51‐centimeter (20‐inch) cable. The
Lightning Protector connects to the outdoor antenna with a standard 6.1‐meter (20‐foot), 7.6‐meter
(25‐foot), 15.24‐meters (50‐foot), or a 22‐meter (75‐foot) low‐loss cable. A longer cable will decrease
the distance achievable between antennas. The ideal location to install your RoamAbout AP and
Lightning Protector must satisfy the following requirements:
• The location must be indoors to protect the AP from extreme weather conditions, excessive
heat and humidity, and to keep the unit free from vibration and dust.
• The Lightning Protector and antenna mast must be connected to the same earth ground (using
separate grounds), as the AC wall outlet ground using an equipotential bonding conductor.
• The location must provide a connection to the network backbone via an Ethernet LAN cable
going to a hub, bridge, or directly into a patch panel.
• The location must be close to where the low‐loss antenna cable will enter the building. The
low‐loss cable connecting the antenna to the Lightning Protector should not exceed 75 feet in
length for 2.4 GHz, or 50 feet in length for 5 GHz, due to the distance reduction with longer
cables.
