Hub Installation Detail
Installation Detail – Outdoor Junction Box (OJB)
The Multi-Sector configuration consists of two or more ARCi Hub antennas mounted on a common
building roof or tower/monopole structure served by a single Wireless Hub (WMTS) located in an
adjacent equipment room.
Each hub requires a separate Upstream and Downstream IF cable, so a six sector (six ARCi Hub)
installation would require 12 IF coaxial cables. The DC power and telemetry cables are simply
paralleled in a multi-sector configuration. This can be accomplished by running separate
power/telemetry cables from each ARCi Hub antenna to the equipment room, or by installing an
Outdoor Junction Box (OJB) on the mounting structure adjacent to the Hub antennas and paralleling the
DC power and telemetry in the OJB.
Implementation
Pictured below (Figure E5) is ARCi’s implementation of an OJB as its test site.
