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. 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 (orwhere FCC rules apply), that only those antennas certified with the product areused. The use of any antenna other than those certified with the product isexpressly forbidden in accordance with FCC rules CFR47 part 15.204. The installer should configure the output power level of antennas according tocountry 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) 02030311-07 Airspan Networks Inc. 6-11
Installing the BSR Hardware Installation Guide The following lists the BSR-to-third party antenna cable setup:   Cable (third party): RF coaxial Connector (third party): N-type male (two N-type connectors for BSR model for 900 MHz band. The N-type socket labeled Primary is used only if one antenna is connected. If you are using two antennas for diversity coverage, attach the second antenna to the other N-type socket.) 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 socket. This eliminates the risk of damaging the BSR device. 6-12 Airspan Networks Inc. 02030311-07
Hardware Installation Guide Installing the BSR To connect the BSR to a thrid-party external antenna:  Attach the third-party N-type male connector, at the end of the RF cable, to the N-type socket located on the BSR’s front panel, as displayed in Figure 6-10. Notes: 1) For crimping cables for N-type connectors, see Appendix B, “Cable Crimping”. 2) Ensure that the third-party antenna cable is of sufficient quality to reduce or eliminate loss when operating in the required frequency band.
