ISM-868-H 868MHz Radio Antenna SMA Male 29cm for LoRa Meshtastic Meshcore

ISM-868-H 868MHz Radio Antenna

ISM-868-H radio antenna with a total length of 29 cm (active section 27 cm) was designed for operation in the 868 MHz ISM band. Thanks to the built-in hinge, the tilt angle can be easily adjusted, which makes it easier to fit into electronic projects. The antenna has a standard SMA male connector, allowing direct mounting in the device socket or on a magnetic base.

The product works great in DIY projects and IoT systems. The antenna can be successfully connected to ESP8266, ESP32, Arduino, and Raspberry Pi modules.
