Low profile LTE wideband antenna for vehicle mounting

　　Low-Profile LTE Broadband Antenna: Smooth and Stable In-Vehicle Connectivity

　　Our low-profile LTE broadband antenna addresses vehicle connectivity challenges—from bulky antennas impacting aerodynamics to signal dropouts at highway speeds. Designed specifically for automakers, in-vehicle router vendors, logistics fleet managers, and telematics solution providers, this ultra-thin antenna provides reliable LTE connectivity for in-vehicle WiFi, real-time GPS tracking, remote vehicle monitoring, and OBD-II data transmission, while seamlessly blending in with the vehicle's design.

　　Key Advantages of In-Vehicle Installation

　　1. Ultra-Thin Design: Aerodynamic and Discreet

　　With a thickness of ≤8mm and a compact footprint (typical dimensions: 100mm × 80mm × 8mm), this antenna sits virtually flush with the vehicle's surface, eliminating the wind noise, drag, and aesthetic issues associated with traditional protruding antennas. It seamlessly fits on the roof, trunk lid, or side panels of all vehicle types: passenger cars (sedans, SUVs), commercial trucks (vans, trucks), RVs, and even specialty vehicles (ambulances, police cars). The slim profile also reduces the risk of damage from low-hanging obstacles (such as garage doors and tree branches) during everyday use.

　　2. Automotive-Grade Durability: Built to Withstand Extreme Conditions

　　Designed to stringent automotive industry standards, it withstands the rigors of road use: operating stably in temperatures ranging from -40°C to 85°C, with no signal degradation even on cold winter roads and in the scorching summer sun. With an IP68 water and dust resistance rating, it withstands heavy rain, snow, and road dust, even in off-road or coastal environments where typical antennas might corrode. It also passes ISO 16750 vibration testing (withstanding vibration frequencies up to 20G), ensuring no loose connections or performance degradation during bumpy or high-speed driving. 3. Dynamic Signal Stability: Stay Connected Anytime, Anywhere

　　Covering all major LTE bands (700MHz–2700MHz, including Bands 1/2/3/4/5/7/8/12/13/17/20/28), it adapts to global cellular networks—maintaining your vehicle's connection whether driving in Europe (Vodafone, Orange), North America (AT&T, T-Mobile), or Asia (SoftBank, China Unicom). Its optimized gain (5–7dBi) balances signal range and power efficiency, while its dual linear polarization (±45°) design reduces multipath interference from buildings, tunnels, and other vehicles. It maintains stable data transmission even at speeds up to 120 km/h, minimizing dropped calls during video calls, GPS tracking, or in-car streaming. 4. Tool-Free Installation: Damage-Free

　　Designed for easy installation, this antenna supports two flexible mounting options: high-strength 3M adhesive for quick, damage-free attachment to smooth surfaces like vehicle roofs, or bolt-on mounting for permanent installation on commercial trucks or RVs. The adhesive is heat- and vibration-resistant, ensuring the antenna's secure attachment for over five years without the need for drilling or modifying the vehicle's paint or body. Installation takes less than 10 minutes, making it ideal for both factory installation (in partnership with automakers) and aftermarket upgrades (for fleet retrofits).

　　5. Wide Compatibility with In-Vehicle Devices

　　It works seamlessly with all common in-vehicle LTE devices: in-vehicle WiFi routers (in-vehicle WiFi hotspots), telematics control units (TCUs), OBD-II diagnostic tools, GPS trackers, and smart dashcams. Compatibility with major automotive chip brands (Qualcomm, MediaTek) and device manufacturers (Cisco, Sierra Wireless) reduces integration costs for in-vehicle device vendors (Vehicle Equipment Suppliers). Standard SMA/RP-SMA connectors ensure plug-and-play integration, eliminating the need for custom adapters. Key Technical Specifications

　　This low-profile LTE antenna operates in the 700MHz to 2700MHz frequency range, supporting global LTE networks and ensuring connectivity during intercontinental travel. It offers a gain of 5-7dBi, optimized for signal strength and power efficiency in mobile scenarios, and features dual linear polarization (±45°) to minimize interference in dynamic environments. It supports a maximum input power of 30W, matching the transmit power of most automotive LTE modules, and features compact SMA or RP-SMA connectors for easy integration. Measuring 100mm × 80mm × 8mm (L × W × D) and weighing 60g, it maintains an ultra-slim profile. Its housing (made of UV-resistant, flame-retardant PC/ABS plastic) meets IP68 protection standards, ISO 16750 vibration resistance standards, and UL94 V-0 fire safety requirements. It is CE, FCC, RoHS, and REACH certified, ensuring compliance with global automotive regulations. Ideal Application Scenarios: Passenger Cars: Provide in-car Wi-Fi for families, enabling rear-seat streaming (movies, games) and real-time navigation updates—without bulky external equipment.
