Hardware Installation Guide Installing the BSR
6.3. Connecting Third-Party External Antennas
(Optional)
A third-party external antenna can be attached to the BSR model providing an N-
type port. These BSR devices do not contain internal, built-in antennas. The addition
of an external antenna allows greater RF sector coverage than the standard BSR
Internal Antenna model (i.e., 60°). The BSR with an external antenna is especially
suited for Base Stations with one BSR, where sector coverage can be increased to
360° by using an omni-directional antenna.
The BSR model for the 900 MHz and 700 MHz bands provide two N-type
connectors for attaching two external antennas. This provides dual-antenna diversity.
Warning: It is the responsibility of the person installing the WipLL system
to ensure that when using the outdoor antenna kits in the United States (o
r
where FCC rules apply), that only those antennas certified with the product are
used. The use of any antenna other than those certified with the product is
expressly forbidden in accordance with FCC rules CFR47 part 15.204. The
installer should configure the output power level of antennas according to
country regulations and per antenna type.
Warning: For WipLL 700 MHz, 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)
