2J2115B-433-B05H 433MHz, ISM, LoRa wall mount Antenna SMA-M 300cm

This high-performance wall mount antenna is optimized for ISM, SigFox, and LoRa applications operating on the 433 MHz frequency. Its omnidirectional design ensures reliable 360-degree signal coverage, making it ideal for home and office monitoring, metering, asset tracking, and remote control devices. The antenna delivers strong signal strength even through walls and buildings, providing robust connectivity in urban environments. With a peak gain of ~2.4 dBi and high efficiency, it is well-suited for low-power, long-range wireless applications.
