Low PIM SISO Directional In-Building Antenna (698-3800MHz)
High-capacity commercial environments require precision-engineered telecommunications components to maintain uninterrupted data and voice services. Hefei BRI Electronic & Technology Co., Ltd. manufactures the Model BR1BB108A siso indoor panel antennas specifically for rigorous das antenna system deployments. This component ensures optimal signal directivity and power distribution across multi-operator cellular networks.
Advanced Broadband Capability for 5G Infrastructure
Operating continuously across the 698-3800MHz wideband spectrum, this 5g cellular antenna fully supports legacy sub-1GHz public safety bands alongside high-frequency 3800MHz 5G NR architecture. The integration of these frequencies into a single hardware unit streamlines indoor das antennas deployments, eliminating the necessity for redundant infrastructure and minimizing architectural footprint.
Exceptional Intermodulation Suppression
Maintaining signal purity is critical in high-density multi-carrier networks. This unit delivers exceptional passive intermodulation performance, rated at ≤-153dBc @ 2x43dbm. This stringent PIM specification is reinforced by the inclusion of a premium 4.3-10 Female connector, which guarantees superior electrical contact and mechanical stability regardless of the installation torque.
Optimized Directional Radiation Pattern
Designed for strategic antenna wall mount placements, this directional antenna provides targeted sector coverage. The horizontal and vertical beamwidths are meticulously calibrated across all operational bands—achieving up to a 90° horizontal beamwidth at lower frequencies and maintaining a tight 50° vertical beamwidth at higher frequencies. Encased in a durable, white ABS radome and measuring just 165x155x48 mm, it offers a highly discreet form factor for professional enterprise environments.
