Circular Polarized Ultra-Wideband Antenna for IoT, M2M, and Tunnel Deployments

The HELI-33 is part of Poynting’s HELI antenna series, designed to provide robust and reliable ultra-wideband connectivity across the 617 to 4200 MHz spectrum. This antenna is ideal for cellular and IoT/M2M applications, excelling in tunnel environments where telemetry and mining automation require stable communication. The circular polarization enhances signal propagation around bends, ensuring uninterrupted connectivity even in non-line-of-sight (NLOS) scenarios, while offering immunity to signal-disrupting elements like trains and drilling machinery.

Ultra-Wideband Frequency Coverage: Operates from 617 to 4200 MHz, supporting a wide range of cellular and IoT applications.
Optimized for Tunnel Communications: Designed to ensure reliable telemetry and automation in mining and industrial tunnels.
Circular Polarization: Enhances signal propagation around bends, minimizing disruptions in non-line-of-sight conditions.
Low Passive Intermodulation (PIM): Meets -150dBc at 2 x 20 W inputs, reducing interference for mission-critical applications.
High-Gain Performance: Offers 10 dBic peak gain, ensuring consistently strong signal performance across all operational frequencies.
Non-Line of Sight (NLOS) Propagation: Overcomes obstacles such as mining equipment, tunnel curvature, and metallic surfaces.
Durable and Reliable Construction: Engineered for harsh underground conditions, making it an ideal solution for industrial deployments.

The HELI-33 is a versatile and high-performance antenna, delivering resilient and stable connectivity for cellular, IoT, and M2M applications in demanding environments, particularly tunnels and underground networks.
