1-2 Enterprise Wireless LAN Antenna Specification Guide
1.1.1 Connector Types and Definitions
There are combinations of antenna types and cables required to provide a satisfactory connection to the AP.
One confusing factor is “reverse polarity”. Reverse polarity is the FCC's requirement for each WLAN
manufacturer to have unique access point connectors. Motorola Solutions had previously standardized our
offerings for access points/ports:
• 2.4 GHz is Reverse polarity BNC female (RP-BNC-F)
• 5 GHz is reverse polarity SMA female (RP-SMA-F)
• Dual Band is reverse polarity SMA female (for AP-5131), and N-Female (for AP-5181).
The following are the connectors used within this guide:
Figure 1.1 RP-BNC-F
Figure 1.2 RP-BNC-M
NOTE: Reverse polarity presents confusion because of a lack of a standardized definition
from connector manufactures. Reverse polarity provides a center element, which should
not be confused with a male connector. A male connector is defined by the outer jacket of
the connector rather than the center element.
