868MHz LoRa Antenna SMA Male RF Omnidirectional

Product Overview

The 868MHz LoRa SMA Male Omnidirectional Antenna is engineered for long-range wireless applications, LoRaWAN systems, and IoT RF nodes operating within the European and international 868 MHz ISM frequency band. Designed for balanced gain and omnidirectional coverage, it enables dependable communication across dispersed sensor networks and industrial telemetry hardware.

RF Performance and Specifications

Optimized for low-power wide-area network transceiver modules, this antenna features a center frequency of 868 MHz with a 50 Ohm input impedance. It delivers an average gain of 2.5 dBi and maintains a low Voltage Standing Wave Ratio (VSWR) of less than or equal to 2.0, providing excellent signal radiation efficiency and reduced transmission reflection for extended battery life in field devices.

Mechanical Design and Compatibility

Built with a robust thermoplastic radome, the antenna features an integrated SMA Male connector with internal threads and a center contact pin. This allows direct, tool-free mounting to SMA Female bulkheads, breakout boards, RF enclosures, and LoRa gateway nodes, offering mechanical stability and resistance against mechanical stress.

Target Applications

This antenna is tailored for smart metering networks, remote agricultural sensors, smart city infrastructure, and DIY development boards such as ESP32 LoRa transceivers, Arduino RF nodes, and Raspberry Pi LoRaWAN hats.
