The HCR dual-band and HCR tri-band rotatable shell omnidirectional antennas are built to withstand extreme industrial conditions. Both antennas are rated for temporary water immersion, can withstand temperatures from -40 to 70 °C and offer a variety of vandal-resistant mounting options. The antenna platform provides frequency agility, low visibility, wide bandwidth and a low-angle radiation pattern. Applications include industrial and the Internet of Things, which the company says requires that more equipment remain constantly connected regardless of the surrounding conditions.
