Key Features and Industrial-Grade Engineering
This antenna is a professional-grade product combining precision RF tuning with rugged physical construction for superior, long-term performance.
Precision RF Performance in the C-Band
Dedicated C-Band Frequency: Precisely tuned to the 3.7 GHz to 4.2 GHz spectrum. This is a critical band used globally for various high-speed applications, including licensed and unlicensed Fixed Wireless Access (FWA) and satellite communications.
High 8dBi Gain: This robust gain figure maximizes the effective radiated power (ERP) of your base station or gateway, significantly extending the coverage footprint and increasing link reliability for remote clients.
Omni-Directional Coverage: Provides a uniform 360-degree horizontal radiation pattern, making it the ideal central antenna for point-to-multipoint (PMP) distribution systems where client devices are located in various directions.
Low VSWR: Built for high efficiency, the antenna maintains an excellent Voltage Standing Wave Ratio (VSWR) , which ensures minimal power is reflected back into the radio, maximizing the available transmission power.
Vertical Polarization: Utilizes vertical polarization, the standard orientation for most terrestrial wireless communication and client CPE (Customer Premise Equipment).
Unmatched Outdoor Durability
Weatherproof Fiberglass Radome: The tough Fiberglass Reinforced Plastic (FRP) casing provides a sealed, impenetrable barrier against the elements. This material offers superior resistance to UV radiation, ice, wind, and corrosive salt spray, guaranteeing a long operational life.
Industrial Temperature Range: Designed to operate flawlessly across a broad range of temperatures (typically $-40^\circ\text{C}$ to $+70^\circ\text{C}$), ensuring reliability in extreme climates.
High-Integrity Connector: Equipped with a standard, weatherproof N-Type Female Connector (or specified connector), which is essential for creating a durable, low-loss connection with high-quality feeder cable.
Robust Mounting Hardware: Includes heavy-duty mounting kits (U-bolts or clamps) engineered to provide secure, stable installation on masts or towers, resisting high wind loads.
Essential Application Scenarios
The specialized frequency and high gain of this antenna make it indispensable for demanding professional applications requiring high-capacity data transmission over long distances.
