Antenna Description

Connecting Home and Office with High Performance and Reliability

2J2115B-433-B05H is designed for ISM, SigFox and LoRa standards and caters to devices that operate on the popular 433 MHz frequency. The license-free 433 MHz is the most widely used ISM band with a powerful point-to-point range for low power devices such as home and office monitoring, metering, tracking and remote controls. With the power of mesh networks, this antenna extends the range of device connectivity with improved reliability. The omnidirectional 360-degree signal optimization offers a powerful signal strength through walls and buildings ideal in urban environments. This high-performance antenna has ~2.4 dBi 433 MHz ISM peak gain and high ~53% efficiency.

For detailed antenna specifications, please see our comprehensive datasheet.

Suggested applications include:

- RFID and Asset Tracking
- Low Power Monitoring
- Metering
- Emergency Response
- Low Power Equipment
- Openers and Remote Controls
- Transmitters or Receivers (one-way)
- Household and Smart Home
