Connecting Third-Party External Antennas Hardware Installation Guide

Warning: For ASWipLL 700 (i.e. 700 MHz band), where four BSRs are
installed at a Base Station, a 1-meter separation must be provided between the
antennas of the BSRs operating in the lower frequencies (i.e. 711.5 and 714.5
for 1 Msps mode; and 712 and 714 for 1.33 Msps mode) and the antennas of
the BSRs operating in the upper frequencies (i.e. 741.5 and 744.5 for 1 Msps
mode; and 742 and 744 for 1.33 Msps mode).
Warning: In accordance with FCC regulations, ensure that when operating in
unlicensed bands, the external antennas provide a maximum EIRP of 36 dBm
to prevent interference with other radios operating in the unlicensed band. The
EIRP is defined as:
Max. Power Output + Antenna Gain + Cable Loss ≤
≤≤
≤ 36 dBm (EIRP)
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 models (i.e. in 700 MHz and 900 MHz bands)
with two N-type ports:
! If you are using only one antenna, connect the antenna to the N-type port
labeled Primary.
! If you are using two antennas, connect the second antenna to the N-type port
labeled Secondary.
Warnings:
1) Before connecting the external antenna, ensure that the BSR is NOT
connected to the power source.
2) Before powering on the BSR, ensure that some type of equipment such as
an antenna or an RF attenuator is connected to the N-type port. This eliminates
the risk of damaging the BSR device.
