About This Guide
Introduction
This guide provides an RF engineer a catalog of antenna parts and accessories to complete a customized RF
environment. This guide specifically addresses the antennas used for 802.11a, 802.11b, and 802.11g
implementations for Wireless Local Area Networks (WLANs).
It is important to understand that antenna and accessory selection should be qualified by on-site testing with
the actual components used. Signal attenuation is cumulative with each connection and component added
between the antenna and the radio, so careful study should verify the given arrangement delivers the
expected results.
Document Conventions
The following conventions are used in this document to draw your attention to important information:
NOTE: Illustrations displayed in this guide are samples and can differ from the actual
antenna.
NOTE: Indicate tips or special requirements.
CAUTION: Indicates conditions that can cause equipment damage or data loss.
WARNING! Indicates a condition or procedure that could result in
personal injury or equipment damage.

Antenna Selection and Description
1.1 Antenna Selection
While several antennas may work in a given environment, some will provide better coverage than others.
Using the right antenna in the right location will maximize both the performance and coverage of your
network. Understanding the key characteristics that describe how an antenna sends and receives radio
frequency signals is critical to finding the ideal antenna for your deployment. This guide supports the
antennas used for an AP-5131 or AP-5181 model access point and an AP300 (non-integrated antenna) model
access port.
Motorola Enterprise Wireless LAN products operate in the 2.4 GHz and 5 GHz ISM bands allocated for
unlicensed use. Access point and access port products available today support either the 802.11b/g or the
802.11a standard, or both. Wireless devices conforming to the 802.11b/g standard operate in the 2.4 GHz
ISM band, while 802.11a devices operate in the 5 GHz band. The antennas in this guide are grouped
according to the frequency band they support. Some antennas are designed to operate on either band. These
antennas (described as "Dual-band") may be connected to radios operating in either the 2.4 or 5 GHz bands,
although a single antenna may not be connected to two radios at the same time.

1-2 Enterprise Wireless LAN Antenna Specification Guide
1.1.1 Access Points and Access Ports Supported
The antennas and accessories referenced in this guide are intended to customize the radiated signal lobes
of Motorola's WLAN product suite.
The access port (AP) supported is the AP300 (Part No. WSAP-5100-100-WWR). This access port has no
integrated antennas and some antenna must be added to the device. The AP300 supports both 5 GHz
(802.11a) and 2.4 GHZ (802.11b/g). The AP300 has two sets of antenna connectors providing diversity (for
each spectrum supported.
The two 5 GHz connectors on the AP300 are - RPSMA-Female
The two 2.4 GHz connectors on the AP300 are - RPBNC-Female
The AP-5131 and AP-5181 access points are also addressed in this document. For an AP-5131, there are
several different part number configurations unrelated to the actual antenna connections. An AP-5131 and
AP-5181 supports both 5 GHz (802.11a) and 2.4 GHZ (802.11b/g). Valid AP-5131 part numbers include:
The AP-5131 supports both 5 GHz and 2.4 GHZ spectrums, but the antenna connectors implemented on the
AP provide dual spectrum capability - both spectrums on one physical connector.
The connectors on the AP-5131are RP-SMA-Female.
The AP-5181 is used outdoors and only one part number is currently available (AP-5181-13040-WWR). Since
this device is intended to be mounted outside in unpredeicable weather, lightening protection is integrated
into the device design. As such, no additional lightning protection is required.
The connectors on the AP-5181are N-Type-Female.

1.1.2 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 (Symbol) 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 displays the connectors used within this antenna specification 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 .
