9 dBi Linear Polarization Antenna

Description

SBA-U2509L is a compact and efficient 9dBi UHF antenna designed for RFID applications operating within the 902–928 MHz range. With its linear vertical polarization, balanced 65° beamwidth in both horizontal and vertical planes, and weather-resistant IP54-rated aluminum body, it is ideal for reliable medium-range tag reading in both indoor and semi-outdoor environments. The antenna supports pole-mount installations and performs well under moderate environmental stress.

Features & Benefits :

• Frequency Range: 902–928 MHz (UHF)
• Gain: 9dBi for effective medium-range coverage
• Vertical Linear Polarization for consistent tag capture in specific orientations
• Beamwidth: 65° H / 65° V for wide directional coverage
• VSWR ≤1.3 for enhanced signal reflection control
• Front-to-Back Ratio ≥20 for reduced interference from behind
• Connector Type: N-type socket
• Durable aluminium build with IP54 waterproof protection
• Mounts on poles with diameters from 40–50mm
• Wind resistance up to 50m/s and operating temperature range of -20°C to +60°C
• Lightning protection through DC grounding

Applications :

• Shelf-level or zone-based inventory tracking
• Access control at medium-range RFID gates
• Warehouse management and logistics
• Industrial workstations requiring focused tag reading
