Product Description

Product Description

  The GL900SPD12 is an industrial-grade parabolic wireless bridge antenna engineered to deliver reliable, long-range connectivity for outdoor and challenging environments. Built with a 18 dBi high-gain die-cast aluminum reflector and low VSWR (≤1.5), it amplifies signal strength while minimizing reflection, ensuring efficient, stable transmission over distances of up to 20 km under clear line-of-sight conditions. 
Its rugged design features a UV-stable coating and low wind-load structure, enabling it to withstand harsh weather, corrosion, and high winds without performance degradation. The antenna supports both vertical and horizontal polarization, paired with a tilt-and-swivel bracket for precise alignment—making it flexible for point-to-point backhaul, rural broadband access, industrial IoT data transmission, and critical infrastructure surveillance.
With a standard N Female connector (and customizable options), it is compatible with most wireless bridge and radio devices operating in the 820–960 MHz frequency band. Whether for connecting remote industrial sites, delivering broadband to underserved rural areas, or maintaining resilient emergency communications, the GL900SPD12 combines durability, performance, and versatility to meet the most demanding wireless connectivity needs.

Functional Advantages

High Gain & Low VSWR

It delivers strong signal amplification (high gain) while minimizing signal reflection (low VSWR), ensuring efficient and stable signal transmission.

 

Durable & Weather-Resistant Construction

The die-cast aluminum reflector and UV-stable coating provide excellent resistance to corrosion and UV damage, making it suitable for long-term outdoor use.

Low Wind Load & Flexible Installation

Its low wind load design reduces stress on mounting structures during windy conditions, and it supports both vertical/horizontal polarization, along with a tilt-and-swivel bracket for precise alignment.

Core Applications

Long-Range Point-to-Point (PtP) Wireless Backhaul
It creates stable, high-bandwidth wireless links between remote locations (e.g., industrial parks, mining sites, or rural campuses), eliminating the need for costly fiber optic cabling.

Rural Broadband Access 
Leveraging the 900MHz band's strong diffraction capability, it delivers reliable internet connectivity to rural homes and small businesses where wired infrastructure is unavailable.
 
Industrial IoT (IIoT) Data Transmission 
It supports seamless connectivity for sensors, telemetry devices, and automation systems in harsh outdoor environments like farms, oil fields, and factories, ensuring continuous data flow.
 
Critical Infrastructure Video Surveillance 
It transmits high-definition security camera feeds over long distances for airports, power grids, and railway networks, with its high gain ensuring stable, low-latency video transmission.
 
Public Safety & Emergency Communication 
During natural disasters or network outages, it acts as a resilient emergency communication link, connecting command centers to field teams to maintain operational continuity.

 

FAQ

Q1:How do I adjust the polarization (vertical/horizontal) for maximum signal strength?
 A: This antenna supports both vertical and horizontal polarization. Use the included tilt-and-swivel bracket to align the antenna's polarization with the receiving device's polarization. For optimal results, perform a signal strength test while adjusting the angle, and lock the bracket once the strongest signal is detected.

Q2:Can this antenna withstand strong winds and harsh outdoor conditions?
 A: No, most models are designed for DIY installation with included mounting hardware (roof mounts, pole mounts, and brackets). However, professional installation is recommended if you need to mount the antenna on a tall roof, in hard-to-reach areas, or if you lack experience with electrical wiring—this ensures proper alignment and reduces the risk of injury or antenna damage.
 
Q3:  What is the maximum transmission distance this antenna can achieve?
 A: With its 18 dBi high gain, this antenna typically supports point-to-point transmission distances of 5–20 km under clear line-of-sight conditions. The actual range may vary based on environmental factors such as terrain, interference, and transmitter power.
 
Q4: How often do I need to perform maintenance on this parabolic antenna?
 A:This antenna requires minimal maintenance. We recommend inspecting the mounting bracket for tightness and cleaning the reflector surface 1–2 times per year (or after extreme weather events like storms) to remove dust, debris, or corrosion. No regular calibration or part replacement is needed under normal use.

Q5:  Is this antenna compatible with wireless bridge devices from other brands?
A:Yes. It uses a standard N Female connector (or customized options) and operates in the 820–960 MHz frequency range, so it is compatible with most wireless bridge, router, or radio devices that support the same frequency band and connector type.
