Antena Radiowa ISM-868-H 868MHz SMA męskie 21cm do LoRa Meshtastic Meshcore

Radiora ISM-868-H 868 MHz SMA antenna

Radiora ISM-868-H is a short 21 cm antenna designed for use in the licence-free ISM 868 MHz band. A built-in hinge makes it easy to adjust the tilt angle, which simplifies alignment in electronics projects. The antenna has a standard SMA male connector, allowing direct mounting in the device socket or on a magnetic base.

It performs very well in DIY and IoT systems. You can reliably connect this antenna to ESP8266, ESP32, Arduino, and Raspberry Pi modules.
