Spring antennas stand out in the world of wireless communication due to their unique helical coil design. Unlike rigid antennas, these flexible wonders absorb shocks, vibrations, and impacts, making them ideal for rugged use in vehicles, outdoor equipment, and portable devices. Our spring antennas support 3G, 4G, and 5G frequencies, delivering omnidirectional coverage with high gain (up to 5dBi) and low VSWR for minimal signal loss.
Key advantages include:
Superior Durability: Helical spring structure withstands bends, twists, and harsh weather.
Waterproof Protection: IP67-rated housing resists dust, rain, and submersion.
Wide Frequency Bands: Compatible with GSM, LTE, 5G NR (617-6000MHz range).
Easy Installation: Threaded connectors (SMA, N-type) for quick setup on routers, modems, and hotspots.
Compact Yet Powerful: Small footprint with extended performance.
Engineered in China with premium copper coils and ABS/metal housings, our spring antennas meet international standards like CE and RoHS. Perfect for telecom operators, fleet management, smart agriculture, and surveillance systems.
Our spring antenna lineup combines cutting-edge materials and precision manufacturing for optimal performance. Here's what sets them apart:
Flexible Helical Design: The coiled spring body provides 360-degree flexibility, preventing breakage from movement or accidental drops. Ideal for automotive telematics or handheld scanners.
Broadband Compatibility: Covers 3G (900/1800/2100MHz), 4G LTE (700/850/1700/1900/2100/2600MHz), and 5G (n78/n41 bands up to 6GHz). Achieve seamless multi-band operation without swapping antennas.
High Gain & Efficiency: 2-5dBi gain ensures stronger signals over distance, boosting download speeds by up to 30% in weak coverage areas.
Rugged Build: IP67 waterproof and dustproof rating, operating from -40°C to +85°C. UV-resistant coating for long-term outdoor exposure.
Versatile Connectors: Options like RP-SMA male, N-female, and TS9 for compatibility with Huawei, TP-Link, Ubiquiti, and Cisco devices.
Customization Available: Tailor length (10-30cm), coil diameter, and impedance (50Ω) to your specs.
Compare our models:
Model | Frequency Range | Gain | Connector | Height | IP Rating |
SA-5G-Spring-02 | 698-6000MHz | 5dBi | SMA Male | 15cm | IP67 |
SA-4G-Flex-01 | 698-2700MHz | 3dBi | N-Female | 20cm | IP67 |
SA-3G-Coil-Pro | 800-2500MHz | 4dBi | RP-SMA | 12cm | IP67 |
All spring antennas undergo rigorous testing for PIM, insertion loss, and radiation patterns to guarantee reliability.
Spring antennas excel where traditional antennas fail. Their resilience shines in dynamic scenarios:
Automotive & Fleet Tracking: Mount on trucks, buses, or drones for GPS/4G/5G connectivity amid vibrations.
IoT & Smart Devices: Power sensors in agriculture, logistics, and metering with stable, low-profile signals.
Outdoor WiFi & Hotspots: Enhance coverage for RVs, boats, or construction sites with weatherproof performance.
Industrial & Security: Use in CCTV systems, remote monitoring, and machinery for uninterrupted data transmission.
Portable Gadgets: Ideal for body cams, walkie-talkies, or rugged laptops needing flexible mounting.
Real-world example: A logistics firm in Southeast Asia integrated our 5G spring antennas on delivery vans, reducing signal dropouts by 40% and improving route optimization.
