Product Description

  The GL-DYS120AM4P is a high-performance, 4-sector divided panel dual-band antenna designed for reliable C-band (4GHz) and Ku-band (12.5GHz) communication, delivering exceptional signal performance and durability for professional satellite communication applications.
 
Core Performance Advantages
 
High-Gain Dual-Band Operation
 
Delivers a robust 34.2dB gain at 4GHz (C-band) with optimized performance at 12.5GHz (Ku-band), ensuring strong signal capture and transmission efficiency for long-range satellite links.
Features a 120cm aperture diameter, 45.6cm focus length, and a precise 0.38 F/D ratio, engineered to maximize signal focus and minimize interference for stable, high-integrity communication.
 
Lightweight & Corrosion-Resistant Construction
 
Constructed from high-strength aluminium mesh, the antenna balances lightweight design with structural rigidity, reducing wind load during installation and operation.
Finished with industrial-grade polyester powder coating, offering long-term protection against corrosion, oxidation, and harsh weather conditions, extending service life in outdoor and coastal environments.
 
 
Flexible Installation & Alignment
 
Mounting Type: Pole-mount compatible, suitable for a wide range of fixed installation scenarios.
Precision Alignment: Supports 0–90° elevation adjustment for vertical angle fine-tuning and 0–360° azimuth rotation for full horizontal positioning, enabling accurate satellite signal targeting in any location.
 
Extreme Environmental Resilience
 
Wind Resistance: Maintains stable signal reception at wind speeds up to 25m/sec, can be reset to normal operation after 40m/sec winds, and remains structurally intact without detachment even at extreme wind speeds of 60m/sec.
Climatic Adaptability: Operates reliably across a temperature range of -40°C to +60°C and 0–100% relative humidity, ensuring uninterrupted communication in polar, desert, tropical, and high-humidity outdoor environments.
 
Application Scope
 
Ideal for professional satellite communication stations, remote data transmission, maritime communication, and emergency backup networks, the GL-DYS120AM4P sets a benchmark for reliability and performance in mid-to-large scale satellite communication infrastructure.

Specification

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 and 900 MHz frequency band, 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.
