Product Description

SZ Vodasafe CKJ-ROC4 Drone Signal BoosterIntroducing the VS-ROC4 Drone Signal Booster from SZ Vodasafe--an innovative solution designed to redefine the performance of your FPV systems and drones. Engineered with cutting-edge technology and premium craftsmanship, this tri-band signal booster eliminates signal dropouts, extends transmission range, and ensures stable connectivity, making it the ultimate companion for professional drone pilots, hobbyists, and security enthusiasts alike. Whether you're navigating complex terrains, capturing aerial footage, or conducting long-range missions, the CKJ-ROC4 delivers unparalleled signal enhancement to keep you in control at all times.

Features
Tri-Band Dual-Port Concurrent Operation
The CKJ-ROC4 supports three critical frequency bands-2.4G (2400-2500MHz), 5.2G (5150-5850MHz), and 5.8G (5150-5850MHz)-with dual-port design that enables simultaneous operation across all bands. No more manual switching between frequencies; the booster seamlessly adapts to your drone's communication needs, ensuring compatibility with most mainstream drones and FPV systems on the market. Whether your device relies on 2.4G for long-range stability, 5.2G for interference-free transmission, or 5.8G for high-definition video streaming, the VS-ROC4 has you covered.
Powerful 10W Output for Extended Range
Boasting a maximum output power of 40dBm (10W), this signal booster significantly amplifies your drone's signal strength, extending its operating radius far beyond the original limits. Say goodbye to short-range restrictions and signal fades-explore vast landscapes, reach greater heights, and maintain crystal-clear connectivity even in remote areas. The high-power performance is optimized for both transmission and reception, ensuring bidirectional signal enhancement.
Ultra-Large 8000mAh Rechargeable Battery
Equipped with an 8000mAh high-capacity lithium-ion battery, the CKJ-ROC4 offers long-lasting operation for extended missions. Whether you're on a full-day aerial shoot or a multi-hour security patrol, the battery provides reliable power without frequent recharging. The booster supports 5V/2A fast charging via the Type-C port, allowing you to quickly replenish power between flights. The 4 blue LED indicators keep you informed of the battery level and working status at a glance.
Premium Aluminum Housing for Superior Cooling
Crafted with a full-aluminum shell, the CKJ-ROC4 combines durability with exceptional heat dissipation. High-power signal boosters generate significant heat during operation, and the all-aluminum construction efficiently dissipates heat to prevent overheating, ensuring stable performance even during prolonged use. The robust housing also offers excellent protection against impact, dust, and moisture, making the booster suitable for harsh outdoor environments.

High-Gain Antenna & Low Noise Figure
The CKJ-ROC4 features a high-performance antenna system with impressive gain specifications: 15dB±1 for 2.4G band and 18dB±1 for 5.2G/5.8G bands. This high gain enhances signal reception and transmission, cutting through interference and improving signal clarity. With a noise figure of less than 2.5dB, the booster minimizes background noise, ensuring that the amplified signal remains clean and reliable-critical for high-quality FPV video and precise drone control.
Exceptional Signal Quality & Fast Switching
Engineered for precision, the CKJ-ROC4 delivers outstanding signal quality with an EVM (Error Vector Magnitude) of just 3%@33dBm (compatible with 802.11g 54Mbps OFDM 64QAM BW 20MHz and 802.11a 54Mbps OFDM 64QAM BW 20MHz). This low EVM ensures minimal signal distortion, resulting in smooth video streaming and responsive drone control. Additionally, the TX/RX switch time delay is less than 1μs, enabling instant switching between transmission and reception modes for seamless communication.

Applications
FPV Signal Booster: Enhance signal strength for FPV racing drones, ensuring low-latency, high-definition video transmission for an immersive flying experience.
Drone Signal Extender: Extend the operating range of consumer and professional drones (such as DJI, Parrot, and custom-built models) for aerial photography, surveying, mapping, and inspection tasks.
Security & Surveillance: Ideal for security drones used in perimeter patrols, search and rescue missions, and industrial inspections, where stable long-range connectivity is critical.
Outdoor Adventure: Perfect for drone pilots exploring remote areas, mountainous regions, or large open spaces, where signal coverage is limited.
Customization & Order Information
Customization: Available for logos, packaging, and specific technical requirements to meet your brand or project needs.
Minimum Order Quantity (MOQ): 1 Piece
