상품 특징

• 🔹 3dBi OPTIMIZED GAIN – BALANCED COVERAGE FOR COMPACT DEVICES – Provides stronger signal than basic 1-2dBi stock antennas while maintaining a balanced spherical radiation pattern. Unlike higher-gain antennas (5dBi+) that create vertical “signal blind spots,” 3dBi delivers reliable 360° coverage – ideal for security cameras, NVR systems, and vehicle backup monitors where consistent omnidirectional coverage matters more than extreme range.
• 🔹 TRIPLE BAND COVERAGE – 2.4GHz / 5GHz / 5.8GHz – Supports 2.4GHz (2400-2485MHz) for long-range wall penetration and Bluetooth connectivity, 5GHz/5.8GHz (5150-5850MHz) for high-speed video streaming, FPV drone video transmission, and interference-free wireless surveillance. Fully compatible with WiFi 6, WiFi 5, Bluetooth, and 802.11a/b/g/n/ac standards.
• 🔹 SMA MALE CONNECTOR – UNIVERSAL COMPATIBILITY – Features standard SMA Male（thread inside with pin） connectors. Compatible with: Wireless Security IP Cameras – WiFi surveillance cameras, wireless NVR/DVR recorders Vehicle Backup Cameras – RV, truck, trailer, van rear view reverse cameras and monitors Surveillance Systems – CCTV systems, wireless video recorders FPV Drones & Video Transmitters – 5.8GHz drone racing, FPV goggles, video receivers Routers, PCIe Cards, USB Adapters – WiFi extenders, access points, Bluetooth audio systems
• 🔹 OMNIDIRECTIONAL 360° COVERAGE – NO AIMING REQUIRED – Built with an omnidirectional radiation pattern that captures and transmits signals from all directions. Unlike directional antennas that require precise alignment, our omni-design works perfectly regardless of device orientation – essential for mobile applications like RVs, trucks, and trailer cameras that constantly change direction.
• 🔹 COMPACT 4CM（1.5IN）DESIGN – PERFECT FOR TIGHT SPACES – At just 1.5 inches (4cm) long, these mini antennas fit seamlessly into tight spaces where full-size antennas won‘t work. Ideal for compact NVR systems, wireless cameras, vehicle installations, and space-constrained surveillance setups where minimizing visual impact is important.
• 🔹PREMIUM CONSTRUCTION – DURABLE & RELIABLE – Built with high-quality materials and copper connectors for optimal signal transfer. Operating temperature range: -20°C to +80°C, suitable for both indoor and outdoor use. VSWR < 2.0 ensures efficient power transmission and minimal signal loss.
• 🔹KIT INCLUDES – 2x 3dBi Dual Band Antennas（SMA Male）
