The Ebyte TX868-BLG Series is a professional-grade line of omnidirectional fiberglass antennas designed specifically for the 868MHz band. Engineered for LoRa, LoRaWAN, and Sigfox networks, this series offers multiple gain configurations: 3.0 dBi (260mm), 5.5 dBi (400-550mm), and a high-efficiency 9.0 dBi (850mm) model. Each antenna is optimized for different environments, from dense urban layouts to expansive rural landscapes.
Featuring a rugged, UV-resistant fiberglass radome, the TX868-BLG series is built for permanent outdoor installation with IP67-equivalent weather protection. The N-Type Male (N-J) connector provides a secure, low-loss connection to LoRa gateways and industrial terminals. With a VSWR ≤ 1.5 on most models, these antennas ensure maximum power transmission for reliable long-range IoT communication.

Key Performance Features
① Specialized 868MHz Signal Propagation
The 3.0 dBi model (260mm) produces a wider vertical beam, perfect for urban "canyons" or multi-story IoT deployments. Conversely, the 9.0 dBi model (850mm) compresses energy into a flat horizontal plane to reach distances exceeding 10km in open line-of-sight (LOS) conditions, such as agriculture or coastal monitoring.
② Industrial Weatherproofing
The hermetically sealed fiberglass tube protects internal copper elements from oxidation, acid rain, and heavy winds. Rated for operation between -40°C and +85°C, these antennas are the standard for outdoor infrastructure, requiring zero maintenance after professional mounting on masts or poles.
Ideal Applications
🌐 LoRaWAN Gateways
Ideal for European 868MHz gateways, including Helium miners and TTN network servers requiring stable outdoor coverage.
🏭 Industrial SCADA
Reliable data transmission for wireless industrial terminals, remote PLC monitoring, and oil/gas field telemetry.
🌾 Smart Farming
The high-gain 9dBi variant is perfect for monitoring large-scale irrigation systems and soil sensors across vast acreage.
🏙️ Smart Utilities
Deployment in AMI (Advanced Metering Infrastructure) for water and electricity meters in rugged outdoor environments.
Frequently Asked Questions
1. How do I connect the TX868-BLG to my LoRa module?
The antenna uses an N-Type Male (N-J) connector. To connect to modules with SMA or IPEX interfaces, you will need a low-loss pigtail adapter cable (e.g., N-Female to SMA-Male). We recommend LMR200 or LMR400 cables for outdoor runs to minimize signal attenuation.
2. Is this antenna suitable for EU868 Helium miners?
Yes, the TX868-BLG series is a top choice for Helium (HNT) miners in Europe. Ensure you select the 5.5dBi or 9dBi version for maximum coverage rewards, and don't forget to update your antenna gain settings in the Helium App.
3. Can it withstand extreme wind and storms?
Absolutely. The fiberglass construction and professional mounting hardware are designed for high wind loads. When properly mast-mounted, these antennas provide a stable signal even in severe weather conditions where plastic antennas might fail.
