Core Product Features: Dual Breakthroughs in Wideband Compatibility and Compact Design​

1. Electrical Characteristics: Multi-Band Coverage, Stable & Efficient Signal​

• Ultra-Wide Frequency Adaptation：Operating frequency range of 700-2700MHz, precisely covering mainstream global communication bands—including 4G (700/1800/2100/2600MHz), 5G Sub-6G (700/2100/2600MHz), IoT NB-IoT (800/900MHz), and some 2G/3G transition bands. No antenna replacement is needed for different device standards (4G/5G) or operator differences, making it compatible with 4G/5G CPE, IoT gateways, wireless monitoring, and other terminals.​
• 360° Omnidirectional Radiation (No Dead Angles)：Adopts a 360º omnidirectional radiation structure, allowing signals to spread evenly in the horizontal direction. Compared to directional antennas (which require alignment with base stations), it supports simultaneous networking of multiple devices (e.g., 10+ sensors in a workshop, 5+ phones in a home). It is especially suitable for scenarios with scattered devices and complex signal sources (e.g., shopping malls, industrial workshops).​
• Low-Loss Long-Cable Transmission：Equipped with an RG174 low-loss coaxial cable (length: 1000mm/1m)—it not only meets the need to "place the antenna away from device interference sources" (e.g., attaching the antenna to the outside of a cabinet to avoid electromagnetic interference from internal motherboards) but also allows flexible adjustment of installation positions (e.g., extending from the top of the device to a high unobstructed area). The cable has stable impedance (50Ω, standard impedance for communication devices), effectively reducing signal attenuation during 4G/5G high-speed data transmission (e.g., HD monitoring feedback, 5G cloud gaming).​
• Precision Connector for Stable Connection：Comes with an SMA Male Jack (Inner Thread, Inner Pin)—the connector has precise dimensions, perfectly mating with SMA female sockets (outer thread, outer pin) of most communication devices. It enables smooth plugging and tight connection, avoiding 5G signal fluctuations or 4G disconnection caused by loose connectors, which is especially suitable for industrial equipment requiring long-term stable operation.​

2. Mechanical Characteristics: Patch Design, Adaptable to Space-Constrained Scenarios​

• Ultra-Thin & Compact Shape：As an external patch antenna, it has dimensions of only 116mm×21.6mm and a thickness of less than 4mm (about the thickness of 3 stacked credit cards). It can be directly attached to flat carriers (e.g., device casings, cabinet doors, walls) without occupying three-dimensional space—perfectly solving the problem of "large size and difficulty in embedding small devices" of traditional cylindrical antennas, and compatible with space-sensitive devices such as 5G portable routers and small IoT terminals.​
• Dual Installation Methods for Flexibility：Supports two fixing methods: ① Adhesive Pasting (with high-adhesion 3M adhesive), enabling installation in 3 seconds, suitable for temporary deployment (e.g., exhibition equipment, home routers); ② Screw Fixing (with 2 reserved mounting holes), suitable for long-term stable scenarios (e.g., industrial cabinets, outdoor equipment). Both methods do not damage the installation carrier, adapting to different usage needs.​
• Lightweight & No Burden：Weighing only 20g (about the weight of 1 coin), it does not cause a load even when pasted on lightweight carriers (e.g., plastic casings, acrylic boards) and will not deform the carrier. The antenna body is made of FR-4 epoxy glass cloth substrate, which has both insulation and impact resistance—daily collisions or slight vibrations will not affect performance.​

3. Environmental Characteristics: Compliant & Durable, Adaptable to Multi-Working Conditions​

• Dual International Environmental Certifications：Strictly complies with RoHS & REACH regulations, containing no harmful substances such as lead, cadmium, or PBBs—whether for home use (environments with children), commercial use (shopping malls, schools), or industrial use (supporting food and medical equipment), it meets global environmental requirements, avoiding procurement restrictions due to non-compliance.​
• Wide-Temperature & Weather-Resistant Design：With optimized circuit and material technology, it supports an operating temperature range of -30~+70℃—it can work stably in extreme environments such as extreme cold outdoors in northern winters (-25℃), high temperatures inside cars in southern summers (+65℃), or industrial workshops (+60℃). The antenna surface is coated with an anti-UV layer, which does not age or crack after 3 years of outdoor use; the outer layer of the RG174 cable is made of weather-resistant PVC material, which is oil-resistant and rainproof, extending the outdoor service life.​

Core Advantages: Solving Four Pain Points of Multi-Scenario Communication​

• "One Antenna for Multiple Networks"：The 700-2700MHz range covers all 4G/5G/NB-IoT bands, eliminating the need to purchase separate antennas for different standard devices (e.g., 4G sensors, 5G gateways), reducing inventory and procurement costs—especially suitable for industrial or smart city projects with multi-device networking.​
• "Great Performance in Small Space"：The 116×21.6mm ultra-thin patch design can be embedded in areas where traditional antennas cannot be installed (e.g., inside equipment cabinets, on the side of small terminals), without affecting the overall appearance and layout of the device, adapting to the miniaturization trend of consumer electronics and industrial terminals.​
• "Double Guarantee of Omnidirectional & Low-Loss"：360° omnidirectional radiation eliminates signal dead angles, and the 1m RG174 low-loss cable reduces transmission attenuation. The combination of the two ensures stable 4G/5G signal transmission in complex environments (e.g., buildings with multiple walls, workshops with multiple device interferences), avoiding HD video freezes and IoT data loss.​
• "Plug-and-Play & Long-Term Durability"：Dual installation methods (adhesive/screw) lower the deployment threshold; wide-temperature weather resistance and environmental compliance extend the service life, reducing later maintenance costs—adapting to both short-term temporary projects and long-term stable operation scenarios.​

Multi-Industry Application Scenarios: Covering Communication and IoT Fields​

1. 4G/5G Terminal Scenarios: Outdoor CPE & Portable Routers​

• Compatible with outdoor 5G CPE (Customer Premises Equipment) and vehicle-mounted 4G routers—the antenna is pasted on the device casing or vehicle-mounted metal bracket via adhesive. The 700-2700MHz wide band covers 4G/5G signals of the three major operators, ensuring stable signal reception even in suburban or weak-signal areas; the 1m cable can extend the antenna to the roof or high places, avoiding metal shielding from the vehicle body and improving 5G download speeds (e.g., from 300Mbps to 500Mbps).​

2.Industrial IoT (IIoT): NB-IoT Gateways & Sensors​

• Installed on NB-IoT gateways and wireless sensors (e.g., temperature-humidity, pressure sensors) in industrial workshops, fixed on cabinet doors or device metal surfaces via screws. The wide band adapts to the 800/900MHz bands of NB-IoT; 360° omnidirectional radiation ensures simultaneous networking of multiple sensors in the workshop; the -30~+70℃ temperature resistance adapts to high-temperature workshop environments, and the oil-resistant cable avoids oil erosion, ensuring 24/7 stable upload of industrial data.​

3.Smart City: Smart Terminals & Monitoring Equipment​

• Used for 5G/NB-IoT modules of smart street lights and outdoor surveillance cameras—the antenna is patch-mounted on street light poles or camera casings. The anti-UV coating resists outdoor sun and rain; the 700-2700MHz band supports 5G HD monitoring feedback and NB-IoT street light control signal transmission; omnidirectional radiation ensures no signal dead angles for the camera within a 360° range, avoiding monitoring picture freezes due to angle issues.​

4.Home/Commercial Use: Signal Enhancement & Network Coverage​

• Paired with home 5G routers and mall 4G signal amplifiers, pasted on balcony walls or ceilings via adhesive. The ultra-thin design does not affect home/mall aesthetics; the 1m cable can be far from electromagnetic interference inside the router; the wide band ensures simultaneous connection of phones and tablets from different operators; 360° radiation eliminates signal blind spots in home corners (e.g., bathrooms, bedrooms) or mall corridors, improving the internet experience.​

5.Portable Devices: Mobile Communication Terminals​

• Compatible with portable satellite phones and outdoor emergency communication terminals—the antenna is pasted on the back of the device. The lightweight (20g) and ultra-thin design do not increase the device’s carrying burden; the 700-2700MHz band supports 4G/5G signal reception in emergency scenarios, enabling weak signal capture in remote areas to ensure smooth emergency communication.
