The 4G Omni Fiberglass Antenna with an SMA Male connector is engineered to provide robust, always-on cellular connectivity across the full 4G LTE spectrum. Designed for ease of integration with a massive range of commercial and industrial Internet of Things (IoT) devices, gateways, and fixed wireless terminals, this antenna delivers high-performance signal capture in a rugged, weather-proof package. Its omni-directional pattern ensures reliable 360-degree coverage, making it the ideal plug-and-play solution for maintaining mission-critical data links in diverse and challenging environments.
Key Technical Features and Integration
This antenna combines high-efficiency RF performance with the compact, common interface of the SMA connector, making it highly versatile for various electronic systems.
1. Wideband 4G LTE Coverage
The antenna is precisely tuned to cover the major frequency bands globally, spanning from 698 MHz to 2700 MHz. This wideband capability ensures seamless operation across different generations of cellular technology, including 4G LTE, 3G (UMTS/HSPA), and 2G (GSM/GPRS/EDGE). This universal compatibility is essential for devices deployed internationally or those that need to operate across multiple carrier networks without requiring unique antenna hardware.
2. Omni-Directional Radiation Pattern
As an omni-directional antenna, it provides a full 360-degree horizontal beamwidth. This is a significant advantage over directional antennas, as it eliminates the need for precise alignment with a distant base station. For mobile applications, or for stationary deployments where the device's exact location or the optimal cell tower direction is unknown, the 360° coverage guarantees signal capture from any direction, maximizing network uptime.
3. Industrial Fiberglass Durability
The radome is constructed from industrial-grade fiberglass (FRP). This material is chosen for its superior mechanical strength, UV resistance, and excellent electrical isolation properties. The fiberglass shell protects the sensitive internal radiating elements from extreme weather conditions, including heavy rain, snow, wind, and prolonged solar exposure, ensuring consistent performance and a prolonged operational lifespan in harsh outdoor settings.
4. SMA Male Connector Standard
The inclusion of an SMA Male connector ensures maximum compatibility and streamlined integration. The SMA connector is the industry standard for small-to-mid-sized cellular, Wi-Fi, and GPS devices due to its compact size, secure threaded coupling, and high-frequency performance (up to 18 GHz). Its use here simplifies installation, allowing direct connection to the vast majority of IoT modems, routers, and telematics units without the need for adapters, thereby minimizing connection loss and potential points of failure.
5. High-Efficiency Gain
Engineered for efficient energy transfer, the antenna provides a sufficient level of gain (typically 5 dBi to 8 dBi, depending on the model) across its operating spectrum. This increased gain extends the effective range of the cellular signal, dramatically improving reception quality in areas with weak cellular coverage and ensuring the device can connect to distant cell towers for robust data transmission.
