868 MHz Omnidirectional Antenna (EU868)

This 868 MHz omnidirectional antenna is designed for operation in the European ISM band (EU868) and optimized for LoRaWAN and Helium network deployments.

The antenna provides a stable 6 dBi gain and is precisely tuned to the 868 MHz frequency range, ensuring efficient signal transmission and reduced sensitivity to out-of-band interference.

Key specifications

• Frequency range: 868–880 MHz
• Gain: 6 dBi
• VSWR: ≤ 1.5:1
• Radiation pattern: omnidirectional
• Length: 54 cm
• Mounting: pole or wall

Optimized narrowband performance

Unlike many commercially available antennas designed to cover multiple frequency bands (e.g. EU868 and US915), this antenna is specifically optimized for the European 868 MHz band.

This narrowband design improves signal-to-noise ratio (SNR) and overall receiver sensitivity, which is critical for long-range IoT communication.

Integrated interference filtering

The antenna includes a built-in bandpass filter that operates without attenuation in the working band, while reducing unwanted signals outside the 868 MHz range.

This is especially important in environments with strong GSM 900 MHz transmissions, which can negatively affect LoRaWAN performance.

Installation considerations

The antenna performance depends on installation conditions, including mounting height, terrain, cable quality and connector losses. In optimal conditions, communication range can reach several kilometers.

The antenna housing is grounded to protect against electrostatic discharge. For proper and safe operation, the antenna and mounting structure should be connected to a suitable grounding system.

Applications

• LoRaWAN gateways
