ACASOM ROC-4 10W Dual-Band Signal Booster: The Ultimate Solution for Professional Drone & FPV Long-Range Communication
Pushing the Limits: Solving the Critical Range Challenge in Professional Drone Operations
For professional drone pilots, aerial cinematographers, and industrial UAV operators, the moment the signal bar drops to a single digit is where real challenges begin. Whether you’re capturing a sweeping landscape shot from miles away, inspecting a remote wind turbine, or mapping a vast agricultural field, the inherent range limitation of standard equipment creates a frustrating barrier. This "signal wall" leads to choppy FPV video, laggy control response, and ultimately, aborted missions and lost data.
The core issue lies in the consumer-grade power and sensitivity of standard remote controllers and video transmitters. To reliably perform Beyond Visual Line of Sight (BVLOS) operations or achieve crystal-clear long-range FPV, you need a professional tool that actively manages and strengthens the communication link.
The ACASOM ROC-4 Dual-Band Signal Booster is engineered as that critical tool. It acts as a powerful ground-based communication hub, systematically amplifying both your control commands and live video feed to extend your operational envelope, enhance reliability, and deliver the stable, high-fidelity connection required for mission-critical work.
Product Overview: A Ground Station Powerhouse for the Demanding User
The ROC-4 is built on a simple, powerful principle: provide clean, substantial signal amplification where it matters most—at your ground control station. It integrates high-power RF circuitry, intelligent power management, and robust construction into a single, purpose-built device.
This system is designed for the user who views their drone as a professional tool. Its value proposition is clear: extended operational range, unparalleled signal stability, and all-day field endurance. It is the essential upgrade for commercial drone pilots, industrial inspection teams, serious FPV explorers, and search & rescue units who cannot afford communication failure.
A Triad of Performance: Deconstructing the ROC-4's Core Technologies
1. Dual-Band, High-Power RF Amplification
The ROC-4 employs two independent amplification paths, strategically allocating power across the most critical drone communication bands.
-
The 2.4GHz Band (2400-2500MHz): The Command Backbone.
-
Purpose: Dedicated to robust control and telemetry data. This lower frequency offers better penetration through light obstacles.
-
Performance: With 18dB of transmission gain and a 15dBi antenna, it ensures your pilot commands reach the aircraft with authority, maintaining a rock-solid control link at extreme distances.
-
-
The 5.2/5.8GHz Band (5150-5850MHz): The HD Video Highway.
-
Purpose: Dedicated to high-bandwidth, low-latency digital video transmission.
-
Performance: An impressive 18dBi antenna gain focuses energy, dramatically improving the signal-to-noise ratio for your FPV video feed or HD camera downlink, resulting in a clearer, more stable picture.
-
This frequency isolation prevents control and video signals from interfering with each other, a crucial advantage in congested RF environments.
2. Built for Endurance: Power That Lasts
A booster is useless without power. The ROC-4 integrates an 8000mAh high-capacity lithium battery, enabling multiple hours of continuous operation on a single charge—enough for a full day of demanding fieldwork. A universal Type-C charging port allows for easy replenishment from power banks, solar generators, or car adapters. A clear 4-stage LED battery indicator provides instant status updates for mission planning.
3. Laboratory-Grade Signal Integrity
Professional performance is defined by precision metrics that consumer gear often omits.
-
3% EVM (Error Vector Magnitude): This gold-standard metric for digital signal quality ensures the amplified signal is a near-perfect replica of the original. It translates directly to pristine digital FPV video with minimal artifacting and highly reliable data packet transmission.
-
<2.5 dB Noise Figure: This exceptional receiver sensitivity allows the ROC-4 to "hear" the faintest signals from your distant drone, pulling in clean telemetry and video where other systems see only noise.
-
<1µs TX/RX Switching: This blazing-fast switching speed is vital for seamless bidirectional communication protocols like MAVLink, ensuring instantaneous response between your commands and the aircraft's feedback, which is critical for precise flying and automated missions.

-
Industrial Inspection & Surveying: Reliably pilot inspection drones around critical infrastructure like cell towers, pipelines, and solar farms, far beyond visual range, with a dependable data and video link.
-
Precision Agriculture & Large-Area Mapping: Maintain a strong connection with automated UAVs covering hundreds of acres, ensuring continuous data flow for photogrammetry and crop analysis.
-
FPV Exploration & Long-Range Freestyle: Push the boundaries of your FPV adventures with a robust link that minimizes drop-outs and latency, allowing you to fly farther and more creatively.
-
Public Safety & Search and Rescue: Deploy UAVs for situational awareness over large areas with the assurance of a powerful, reliable communication tether back to the command post.
Installation and Optimization Guide
-
Connection: Connect your remote controller's video output and control signal to the ROC-4's inputs using the provided cables. Connect high-gain, compatible antennas (sold separately or in kits) to the N-type ports.
-
Antenna Positioning: For maximum range, use a directional (patch or panel) antenna on the booster and aim it toward your flight area. Ensure a clear line of sight when possible.
-
Power Management: Monitor the battery LEDs. For all-day events, consider connecting an external USB-C power bank for continuous charging during operation.
Frequently Asked Questions (FAQ)
Q: How much can the ROC-4 actually extend my drone's range?
A: The actual range depends on environment, antennas, and drone model. The ROC-4 significantly improves the "link budget," often effectively doubling or tripling reliable control and video range under ideal line-of-sight conditions compared to stock systems.
Q: Is it compatible with my DJI/Autel/etc. drone?
A: The ROC-4 is generally compatible with systems that have accessible video and control signal outputs (often via the remote controller). It works with standard analog and digital FPV systems, and many prosumer drones. Always check your specific equipment's connectivity.
Q: Does the 10W output require a special license?
A: Regulations vary by country and region. Users are solely responsible for complying with all local laws regarding transmitter power output and frequency use for their specific application (e.g., hobby, commercial, Part 15/Part 90). Always operate within legal limits.
Q: Will it overheat during prolonged use?
A: The rugged aluminum alloy shell acts as an efficient heat sink. For continuous high-power operation in hot environments, ensuring good ventilation is recommended.
