The Ebyte TX4G-BLG Series is a high-performance line of omnidirectional fiberglass antennas designed for full-spectrum 4G LTE connectivity (700–2700 MHz). Engineered for LTE-M, NB-IoT, and cellular broadband networks, this series offers a massive range of gain options from 2.5 dBi for compact urban nodes to an industry-leading 12.0 dBi for long-distance remote sites.
Unlike standard indoor dipoles, the TX4G-BLG features a heavy-duty, UV-stabilized fiberglass radome and an N-Type Male (N-J) connector, providing IP67-rated protection for permanent outdoor installation. With low VSWR and broad bandwidth coverage, these antennas ensure maximum data throughput for 4G industrial gateways and telecommunications infrastructure.
Series Specification Comparison
Select the optimal 4G LTE variant based on your required gain and physical installation constraints:
| Model | Gain (dBi) | Height (mm) | Frequency Range | VSWR | Connector |
|---|---|---|---|---|---|
| TX4G-BLG-25/25L | 2.5 dBi | 250 mm | 700–2700 MHz | ≤ 2.0 | N-Type Male |
| TX4G-BLG-30 | 3.0 dBi | 300 mm | 700–2700 MHz | ≤ 2.0 | N-Type Male |
| TX4G-BLG-55 | 5.5 dBi | 550 mm | 700–2700 MHz | ≤ 1.5 | N-Type Male |
| TX4G-BLG-85 | 8.5 dBi | 850 mm | 700–2700 MHz | ≤ 1.5 | N-Type Male |
| TX4G-BLG-120 | 12.0 dBi | 1200 mm | 700–2700 MHz | ≤ 1.5 | N-Type Male |
*Note: All models feature 50Ω impedance, vertical polarization, and fiberglass radome.

Key Technical Features
① Full-Band Cellular Optimization
The TX4G-BLG series is "future-proof," covering all global 4G LTE bands, including the critical 700MHz low-band for deep indoor penetration and the 2600MHz high-band for high-speed data. The 12.0 dBi flagship model (1200mm) is specifically designed to maintain signal stability in fringe areas where cellular towers are miles away.
② Extreme Weather Resilience
The sealed fiberglass construction is designed to withstand 120km/h wind loads and temperature fluctuations from -40°C to +85°C. The N-Type interface is corrosion-resistant, making it suitable for coastal deployments and harsh industrial environments where plastic enclosures would degrade or crack.
Which gain should you choose?
- Urban Environments: 2.5dBi to 3.0dBi. The wider vertical beam captures signals bouncing off buildings.
- Industrial/Suburban: 5.5dBi. The perfect all-rounder for factory gateways and outdoor clusters.
- Remote/Rural: 8.5dBi to 12.0dBi. High-gain models flatten the signal into a long-distance plane to reach far-off towers.
Ideal Applications
🌐 Industrial 4G Gateways
Primary or failover outdoor antenna for industrial cellular routers (LTE-M/NB-IoT) in remote monitoring stations.
📡 Telemetry & SCADA
Reliable data backhaul for water, gas, and electricity utility meters in rural or obstructed environments.
🎥 Remote Surveillance
Ensures high-speed 4G data links for outdoor security cameras where wired internet is unavailable.
🏙️ Smart Infrastructure
Connectivity for environmental sensors, traffic control systems, and municipal IoT grids requiring durable outdoor antennas.
Frequently Asked Questions
1. Will this antenna improve my 4G signal in a weak area?
Yes. By mounting the TX4G-BLG outdoors on a mast, you bypass building interference. The 8.5dBi and 12dBi models are specifically engineered to amplify weak signals in rural areas to improve data speeds and stability.
2. Is it compatible with 5G networks?
The TX4G-BLG covers frequencies up to 2700MHz, which includes several sub-6GHz 5G bands (like n41). However, for full 5G coverage (up to 6GHz), we recommend our dedicated 5G series antennas.
3. What mounting hardware is required?
All TX4G-BLG series antennas come with industrial U-bolt mounting kits, allowing you to easily attach the antenna to a standard vertical mast or pole (30mm-50mm diameter).
