$67.9
$131.73
Description The HELI-33 forms part of our HELI antenna series, a circular polarized, ultra-wideband antenna designed for optimal performance across the 617 to 4200 MHz spectrum. It is ideal for cellular and IoT/M2M deployments, where it excels in tunnels, providing robust telemetry and enhancing mining automation. The circular polarization enhances signal propagation around bends, ensuring a reliable connection in non-line-of-sight scenarios and offering immunity to signal-disrupting elements like trains and drilling machinery. The HELI-33 also meets low PIM requirements with an impressive -150dBc at 2 x 20 W inputs, minimizing interference for critical applications. With a peak gain of 10dBic across the entire operational band from 617 to 4200 MHz, this antenna guarantees consistently strong signal performance. In summary, the HELI-33 is a versatile solution, delivering reliability, resilience, and peak performance for cellular and IoT/M2M deployments in challenging environments, particularly tunnels.
