External Antennas
This chapter describes the procedures for connecting third-party external radio and
Global Positioning System (GPS) antennas to the BSR and BSDU, respectively. The
implementation of these antennas depends on the BSR model (with respect to radio
antennas) and the need for synchronization of the ASWipLL system (with respect to
GPS antennas).
10.1. Connecting Radio Antennas to BSR
The BSR model without an integrated antenna provides an N-type port(s) for
connecting a third-party external antenna(s). Specific BSR models (refer to the
ASWipLL System Description) provide two N-type connectors for connecting two
third-party external antennas. Two antennas provide dual-antenna diversity, whereby
data is transmitted using only the main antenna, while data is received by the
antenna (main or secondary) with the best radio frequency (RF) reception.
Notes:
1) BSR models that provide N-type connectors for attaching a third-party
external antenna do not contain an internal, built-in antenna.
2) Refer to the ASWipLL System Description for a list of BSR models
implementing third-party external antennas.
The following lists the BSR-to-third party external antenna cable setup:
 Cable (third party): RF coaxial
 Connector (third party): N-type male
The usage of N-type ports for BSR models with two N-type ports:
