Description
The Times-7 A5531 is a unique and exclusive Circularly Polarized Ground Antenna designed for high-performance RAIN (UHF) RFID applications, especially those involving moving products, assets, and people. It is the ideal solution for scenarios like race timing and conference attendee/people tracking where traditional side antennas are unsuitable.
Key Features & Benefits
- Ultra Low-Profile Design: Measuring a mere 10mm (0.4 inches) in thickness, the A5531 is designed to lie flat on the ground, minimizing obstruction.
- Exceptional Durability: The antenna is highly robust, spanning 1.2m (4ft) and capable of handling distributed payloads of over 200kg (440lbs) (with a maximum distributed load not to exceed 1100 lbs/500 kg). It supports moderate loads like runners, bicyclists, hand trolleys, and occasional vehicular traffic with pneumatic tires (requires installation on a smooth, hard surface).
- High Performance: Optimized for ground applications, the A5531C (Circularly Polarized model) provides a typical Far-field Gain of 9.5 dBiC.
- Global Frequency Support: Available in both ETSI (865-868 MHz) and FCC (902-928 MHz) bands.
- Robust Construction: Features a Fire retardant ABS Radome Material and an IP53 Environmental Rating.
