1. Core Features & Advantages

This 433MHz screw-on mount antenna is a high-performance antenna tailored for 433MHz wireless communication. It integrates excellent electrical performance, flexible mechanical design, and reliable environmental adaptability to provide stable support for signal transmission in multiple scenarios.

1. Electrical Performance: Efficient & Stable Signal Transmission

• Precise Frequency Adaptation: Operates at the 433MHz frequency band, perfectly matching devices like IoT terminals, industrial control modules, and wireless meter reading devices in this band, ensuring targeted and stable signal transmission.
• Low Loss & High Gain: With an input impedance of 50Ω, it highly matches mainstream RF systems; the Voltage Standing Wave Ratio (V.S.W.R) is <1.7, greatly reducing signal reflection and improving energy transmission efficiency; the gain reaches 1.6 dBi, enhancing signal reception/transmission capability and expanding the effective communication range.
• Vertical Polarization & High Power Capacity: Adopts vertical polarization design, performing excellently in scenarios requiring directional vertical signal coverage (such as inter-building, long-distance point-to-point transmission); the power capacity reaches 50W, meeting medium/high-power signal transmission needs and providing strong power support for devices.

2. Mechanical Design: Flexible & Easy to Use, Adapt to Diverse Scenarios

• Stable Screw Mounting: Uses screw-on mounting method, which is more structurally stable than magnetic mounting, and can be firmly fixed on device casings, brackets, etc., suitable for long-term stable operation scenarios.
• Customizable Connector & Cable: Equipped with SMA-J male connector (customizable), adapting to interface requirements of different devices; paired with RG174 low-loss cable with a length of 1000mm (1m), the distance between the antenna and device can be flexibly adjusted to fit complex installation layouts.
• Compact & Lightweight Design: With dimensions of 150×30 mm, it is compact and space-saving; weighing only 26g, it won’t add extra burden even when installed on weight-sensitive devices (such as small drones, portable monitoring devices); the black appearance combines practicality with a concise industrial style.

3. Environmental Adaptability: A Reliable Choice in Harsh Scenarios

• Eco-Compliant: Strictly complies with ROHS standards, containing no harmful substances like lead or mercury, balancing performance and environmental friendliness, suitable for civil, industrial, and commercial scenarios with high environmental requirements.
• Stable Operation in Wide Temperature Range: Both operating and storage temperature ranges are -45~+85℃, enabling stable work in extreme conditions such as extreme cold (outdoor in northern winter) and extreme heat (desert areas, industrial high-temperature environments), adapting to multi-regional and multi-working-condition use.

2. Multi-Industry Application Scenarios

• Industrial IoT (IIoT): Used for signal transmission between sensors (pressure, vibration sensors, etc.) and control terminals in factory workshops. Screw mounting can be firmly fixed on machine tools and production line brackets; the 1m RG174 cable adapts to equipment layout; 1.6dBi gain and vertical polarization ensure stable signal intercommunication between production line devices, facilitating industrial automation data collection and control.
• Smart Metering & Energy Management: Paired with wireless transmission modules of smart electricity/gas meters, fixed on meter boxes or outdoor metering devices with screws. The 433MHz band complies with meter reading communication specifications; low VSWR and high gain ensure stable upload of meter reading data (electricity/gas consumption, etc.) to the management platform, even in complex building environments.
• Smart Agriculture: Installed on agricultural monitoring equipment (soil moisture monitoring stations, weather stations, etc.), fixed on field brackets or greenhouse frames with screws. Vertical polarization adapts to "ground-air" signal transmission needs (such as communication between drone inspection and ground stations); wide temperature characteristics ensure long-term stable operation in winter and summer, providing data transmission support for precision agriculture.
• Urban Infrastructure Monitoring: Used for stress/displacement sensors of bridges, tunnels and other municipal facilities, fixed on metal structure surfaces with screws. The 433MHz signal can penetrate some obstructions; 1.6dBi gain expands the monitoring range; -45~+85℃ temperature resistance adapts to large outdoor temperature differences and extreme weather, ensuring real-time transmission of monitoring data to the management center.
• Security & Emergency Communication: Adapted to small security cameras and emergency broadcast terminals, fixed on monitoring poles and emergency equipment boxes with screws. Vertical polarization enhances signal directivity in the vertical direction (such as from ground devices to high-altitude monitoring centers); 50W power capacity supports high-power signal transmission in emergency scenarios, ensuring stable transmission of security images or emergency commands.
