The Sirio SO 868-915-2 NH is a compact omnidirectional base antenna designed for communication systems in the 868MHz and 915MHz bands, especially LoRa, LoRaWAN, ISM and SIGFOX applications.

With operation from 868–915MHz and no tuning required, this antenna makes installation easier in telemetry systems, automation, remote sensors, IoT gateways, technical monitoring and low-power data networks.

The 1/2 wave design provides a simple and efficient solution for omnidirectional coverage in fixed installations. The antenna offers linear vertical polarization, 360° horizontal-plane radiation, 0dBd / 2.15dBi gain and 20W CW maximum power.

The NH / N female version uses an N female connector, suitable for outdoor installations and applications requiring a robust and reliable RF connection. The antenna can be mast-mounted and is suitable for professional, industrial, agricultural, domestic or experimental IoT applications.

With approximate 290mm height and 235g weight, the SO 868-915-2 NH is a compact solution for users requiring an outdoor wideband antenna for 868MHz and 915MHz, with good construction quality and easy integration into radio data systems.

Important note

Before installation, always confirm the operating frequency, connector, coaxial cable, cable losses, transmit power, equipment type, mounting height, support, wind exposure and applicable regulations.

This antenna is intended for systems in the 868–915MHz range. Use with LoRa, LoRaWAN, ISM or SIGFOX must always comply with the legal limits in the country of use, including power, duty cycle, channel plan and service type.

Final performance depends on installation height, obstacles, coaxial cable, connectors, equipment quality, RF environment and antenna location. For outdoor installations, suitable coaxial cable, weather-protected connectors and surge protection where applicable are recommended.

This item corresponds to the Sirio SO 868-915-2 NH antenna with N female connector. Coaxial cable, N male plug, mast, additional bracket, surge protection and other installation accessories are not included unless expressly stated otherwise.
