This high-performance 5 dBi rubber duck antenna is precision-tuned for the 868 MHz and 915 MHz ISM bands, delivering reliable long-range connectivity for LoRaWAN, Zigbee, Z-Wave, RFID, and industrial IoT applications. Engineered with a durable TPE/rubber overmold and reinforced strain relief, it withstands harsh outdoor and industrial environments while maintaining consistent RF performance across temperature extremes. The standard SMA male connector ensures plug-and-play compatibility with gateways, sensors, modems, and embedded modules from leading manufacturers.
Unlike generic omnidirectional antennas that sacrifice gain for size, this 5 dBi design extends link budget by 6–8 dB over 2–3 dBi alternatives, enabling 2–3× greater range or improved penetration through walls and metal enclosures—critical for smart metering, agricultural monitoring, warehouse automation, and asset tracking deployments. Available in stock for immediate shipment, it eliminates lead-time risks for urgent projects or pilot builds.
Fully customizable to your exact requirements: adjust frequency tuning (868/915/920 MHz), connector type (SMA/RP-SMA/N-Type), cable length/pigtail, color, labeling, or mechanical dimensions. All units are manufactured to high-quality standards with 100% electrical validation and pre-certified with CE, FCC, and ROHS for global compliance. Sourced directly from our ISO-certified facility, this antenna offers unmatched availability, consistency, and value for OEMs and system integrators scaling LPWAN networks.

Q: Can this antenna work on both 868 MHz and 915 MHz simultaneously?
A: Yes. It’s dual-band optimized with ≤1.5:1 VSWR at both 868±5 MHz and 915±5 MHz. Ideal for devices sold globally without hardware changes. For single-band precision tuning, specify primary band when ordering—we’ll optimize matching network accordingly.
Q: How does 5 dBi compare to 3 dBi in real-world range?
A: Every 3 dB gain doubles effective range in free space. 5 dBi provides ~6–8 dB advantage over typical 2–3 dBi rubber ducks, translating to 2–3× greater range or significantly better penetration through walls/foliage. Actual gains depend on environment—contact us for site-specific link budget analysis.
Q: Is the SMA connector reversible or gender-specific?
A: Standard configuration is SMA male (threads on antenna). RP-SMA female (reverse polarity) also available for WiFi/LTE modules requiring RP-SMA. Specify connector gender/type when ordering to avoid compatibility issues.
Q: Can I use this outdoors without additional protection?
A: Yes. IP67-rated sealing protects against rain, dust, and humidity. UV-stabilized rubber prevents cracking after years of sun exposure. For submerged or high-pressure washdown environments, specify IP68 variant.
Q: What’s the minimum order for custom versions?
A: 100 units for frequency/connector/cable customization. Standard 868/915 MHz SMA 5 dBi has no MOQ—order as few as 1 unit from stock. Volume pricing starts at 500+ units.
Q: Do you provide test reports for quality verification?
A: Every batch includes VSWR/gain test summaries. Full anechoic chamber patterns and environmental stress data available upon request. Third-party lab coordination supported for carrier/utility acceptance testing.
