Reliable UHF Antenna for M2M, IoT, and Data Links
This compact stud-mount dipole antenna is engineered for wireless data applications in the UHF 900–930 MHz range. Ideal for M2M, IoT, and radio location systems, it delivers consistent 2.1 dBi gain and vertical polarisation in a 360° omni-directional H-plane. Factory-tuned and enclosed in a durable black PVC radome, it features bottom-exit RG316 coaxial cable with an SMA male connector. Compatible with LoRa and ISM bands, it's designed for installation on poles or masts with a minimum 12.7 mm mounting hole.
Key Features
- UHF-wide frequency support: Operates from 900 to 930 MHz, compatible with AU915-928, AS923, and US902-928 bands.
- Omni-directional radiation: Provides 360° coverage in the horizontal plane for broad device connectivity.
- Factory-tuned performance: Offers <2:1 VSWR across the full 30 MHz bandwidth without adjustment.
- Vertical polarisation: Ensures efficient propagation for typical IoT and telemetry use cases.
- Durable, weather-resistant build: Black PVC radome and delrin ferrule support reliable outdoor deployment.
- Lightweight and compact: Measures just 230 mm tall and weighs only 50–90 g, depending on cable length.
- Flexible installation options: Compatible with various mounting brackets; fits 12.7 mm mounting holes.
- Pre-terminated coaxial cable: Supplied with 900 mm or 2 m RG316 cable and SMA male connector.
- Grounded for safety: DC grounding included as standard for protection in harsh environments.
- LoRa and ISM-ready: Perfect for low-power wide-area network (LPWAN) applications.
Purpose-built for UHF telemetry and M2M communication, this antenna delivers stable, efficient performance in a rugged and adaptable form factor.
