The Sirio SCO-868-4N is an omnidirectional colinear base antenna designed for communication systems in the 868MHz band, especially LoRa, LoRaWAN, ISM and SIGFOX applications.

With an operating range of 868 to 870MHz and SWR ≤1.5, this antenna requires no tuning, making installation easier in telemetry systems, automation, remote sensors, IoT gateways, monitoring and low-power data networks.

Its colinear construction provides 2.2dBd / 4.3dBi gain while maintaining omnidirectional horizontal-plane radiation and linear vertical polarization. This makes it suitable for installations requiring coverage in several directions from a fixed point.

The SCO-868-4N version uses an N female connector, suitable for fixed and outdoor installations with compatible coaxial cable. The antenna can be mounted on a mast, wall or through-holes depending on the support and installation method used.

With approximate 500mm height, 280g weight, 20W CW maximum power and DC-Ground protection, the SCO-868-4N is a practical solution for professional and technical projects in the 868MHz band.

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 868–870MHz band. 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 SCO-868-4N antenna. Coaxial cable, N male plug, mast, additional bracket, surge protection and other installation accessories are not included unless expressly stated otherwise.
