IP65 Waterproof UHF RFID Antenna 8dBi 915MHz Circular Polar

IP65 Waterproof UHF RFID Antenna — 8dBi Gain, 915MHz Circular Polarization

Take your RFID system to the next level with this high-performance UHF RFID Circularly Polarized Antenna (Model: UHF902). Designed for demanding real-world deployments, it delivers an impressive 8dBi gain across the standard UHF band (902–928MHz), ensuring reliable, long-range tag reads in access control, warehousing, logistics, retail inventory, and more. The rugged IP65-rated ABS + aluminum enclosure keeps dust and water jets out, making it equally at home indoors or outdoors.

Why Choose This UHF RFID Antenna?

• High Gain & Low VSWR: 8dBi gain combined with a VSWR of ≤1.3:1 maximizes read range and minimizes signal loss.
• Circular Polarization: Reads tags regardless of their orientation — ideal for fast-moving items on conveyor belts, retail shelves, or vehicle access points.
• IP65 Weatherproof: Sealed against dust ingress and water jets; built to withstand harsh environments from cold storage to outdoor loading docks.
• Wide Temperature Range: Operates reliably from -40°C to +85°C — perfect for freezer warehouses, outdoor gates, and industrial settings.
• Universal Compatibility: Standard SMA female connector (side-feed) fits the vast majority of UHF RFID readers on the market.
• Durable Construction: Engineering-grade ABS plastic + aluminum housing, weighing just 850g at a compact 260 × 260 × 45mm footprint.

Ideal Applications

• Warehouse & logistics management (pallet tracking, dock doors)
• Retail inventory management & loss prevention
• Access control gateways & vehicle identification
• Manufacturing production line tracking
• Library management & asset tracking
• Outdoor smart parking systems

Frequently Asked Questions

Q: What RFID readers is this 8dBi UHF antenna compatible with?

A: This antenna features a standard SMA female connector with 50Ω impedance, making it compatible with the vast majority of UHF RFID readers operating in the 902–928MHz band (EPC Gen2 / ISO 18000-6C). Always verify your reader's connector type before purchasing.

Q: Can this UHF RFID antenna be used outdoors?

A: Yes. The IP65 rating means the antenna is fully protected against dust ingress and low-pressure water jets from any direction. Combined with its wide operating temperature range of -40°C to +85°C, it is well-suited for outdoor installations such as parking gates, loading docks, and outdoor access control points.

Q: What is the advantage of circular polarization for RFID?

A: Circularly polarized antennas can read RFID tags regardless of their physical orientation. This is especially valuable in warehouse, retail, and conveyor-belt applications where items move quickly and tags may be positioned at any angle, ensuring more consistent and reliable reads compared to linearly polarized antennas.

Q: What read range can I expect with this 8dBi UHF RFID antenna?

A: Actual read range depends on the RFID reader's output power, the tag used, and environmental conditions. In typical deployments with a standard RFID reader, this antenna's 8dBi gain can support read ranges of several meters, making it suitable for wide-area portal or gateway setups.
