8dBi 868MHz Omnidirectional Fiberglass Helium Antenna is a high-performance antenna designed for long-range, reliable wireless communication. Operating at 868MHz, it provides superior signal coverage with an 8dBi gain, ideal for Helium network applications and IoT deployments. Its rugged fiberglass construction ensures durability in outdoor environments, offering enhanced reliability for various industrial and urban applications.
Gain: The antenna has a gain of 8dBi, which indicates its ability to direct and amplify the radio frequency signal. A higher gain means the antenna can transmit and receive signals over a longer distance.
Frequency Range: It operates at a frequency of 868MHz, which is a common frequency band for low-power wide-area networks (LPWAN) such as the Helium network. This frequency band offers good penetration and coverage characteristics.
Polarization: It is vertically polarized, which is a common polarization method for outdoor antennas. Vertical polarization helps reduce signal interference and improve signal quality in some environments.
Voltage Standing Wave Ratio (VSWR): The VSWR is ≤2.0, which means the antenna has a good impedance match with the transmission line. This helps minimize signal reflections and power losses.
Impedance: The characteristic impedance of the antenna is usually 50Ω, which is a standard value for most radio frequency devices, ensuring compatibility with common radio frequency cables and equipment.
Material: The antenna is made of fiberglass, which is a lightweight, durable, and weather-resistant material. This makes it suitable for outdoor use in various environmental conditions.
Shape and Size: It is typically a cylindrical rod-shaped antenna. The diameter is about 20mm, and the length may vary depending on the specific model, generally ranging from 350mm to 1000mm.
Connector: Common connector types include N male or N female, SMA male or female, etc., which facilitate connection to the radio frequency cable and the Helium hotspot device.
It can be installed on a pole, wall, or roof using U-bolts or other mounting brackets. The omnidirectional characteristic means it can radiate signals in all directions horizontally, so it should be installed in a relatively high and unobstructed location to ensure the best coverage.

Ideal for Helium hotspot operators in urban, suburban, or semi-rural areas, the antenna’s omnidirectional pattern delivers 360° signal distribution to eliminate blind spots in dense neighborhoods or commercial districts. Its 8dBi gain extends coverage across wider spaces, penetrating trees, low-rise buildings, and terrain variations to connect more IoT devices (e.g., smart meters, asset trackers), boosting hotspot efficiency and HNT token rewards.
Suited for smart factories and warehouses, it connects sensors monitoring machinery, temperature, humidity, and inventory—even in large facilities with metal structures or thick walls. The weatherproof design enables indoor/outdoor installation (factory floors, loading docks), supporting automated guided vehicles (AGVs) and real-time inventory management, while withstanding dust, moisture, and extreme temperatures (-40°C to +85°C).
A key component for smart city initiatives, it powers public services like smart streetlights, waste management sensors, air quality monitors, and transit hub devices (passenger displays, security cameras). Its signal penetration through urban clutter (concrete buildings, traffic) ensures seamless data transmission for traffic optimization, public safety, and environmental sustainability.
Perfect for large farms, orchards, and rural areas, the antenna’s high gain and 868MHz frequency propagate signals through foliage and vast distances, connecting soil moisture sensors, crop health trackers, and livestock collars. It enables real-time data access for irrigation optimization, fertilizer use, and livestock monitoring, with a durable design that resists rain, wind, and UV radiation.
Enhances connectivity for smart homes, apartments, offices, and hotels, supporting devices like thermostats, lighting systems, security cameras, and occupancy sensors. The omnidirectional pattern ensures coverage across multiple floors and outdoor areas (parking lots, gardens), enabling remote control, energy efficiency, and personalized customer experiences (hotel room controls, retail marketing).
Reliable for harsh/remote environments (oil/gas fields, mining sites, solar/wind farms), it connects critical sensors for pipeline pressure, leak detection, equipment performance, and personnel/asset tracking. Its durability and high gain ensure continuous connectivity in areas with limited infrastructure, reducing downtime and enhancing safety.
Optimizes shipping and warehousing operations by connecting GPS trackers, temperature sensors (for perishables), and asset tags. It provides end-to-end shipment visibility, streamlines inventory management in distribution centers, and ensures signal strength for long-haul trucking or maritime shipping in remote areas with limited cellular coverage.
