433MHz 9dBi Spring Magnetic Antenna with RG174 (L-3Mtr) Cable + SMA Male Connector

A 433MHz 9dBi spring magnetic antenna with an RG174 (L-3Mtr) cable and SMA male connector is designed for high-performance RF applications in the 433 MHz band. Here’s a detailed look at its components and features:

1. 433MHz Frequency:

   • This antenna is tuned for operation at 433 MHz, which is commonly used for various RF communications such as remote controls, certain types of IoT devices, and some wireless sensors.

2. 9dBi Gain:

   • Gain: The 9 dBi gain indicates a relatively high gain, meaning the antenna focuses the signal more effectively in a specific direction compared to an isotropic antenna. This provides better signal strength and extended range.
   • Directional Pattern: While the antenna is designed to provide a higher gain, it may have a more focused signal pattern, making it suitable for applications where increased range in a specific direction is required.

3. Spring Design:

   • Flexibility: The spring design allows the antenna to be flexible and resilient. This is useful for applications where the antenna might be subject to physical movement or where it needs to be adjusted to different angles.
   • Durability: The spring mechanism helps absorb physical shocks and prevents damage to the antenna.

4. Magnetic Base:

   • Mounting: The magnetic base allows for easy attachment to metal surfaces, providing a stable and secure mounting solution. This also makes it easy to reposition the antenna as needed.
   • Convenience: This feature is particularly useful in temporary or portable setups where flexibility in placement is important.

5. RG174 (L-3Mtr) Cable:

   • Cable Type: RG174 is a flexible, low-loss coaxial cable commonly used in RF applications. It is suitable for connecting antennas to devices over moderate distances.
   • Length: The "L-3Mtr" specifies that the cable is 3 meters long, providing flexibility in positioning the antenna away from the device.

6. SMA Male Connector:

   • Connector Type: The SMA male connector is a standard RF connector used in many applications. It provides a secure connection to the antenna port of your device.
   • Compatibility: Ensure that the SMA male connector matches the antenna port on your device for a proper fit and to prevent signal loss.

• Remote Controls: Suitable for applications requiring reliable communication over moderate distances, such as remote control systems.

• IoT Devices: Ideal for Internet of Things devices operating in the 433 MHz band that require enhanced signal range.

• Wireless Sensors: Useful for wireless sensor networks where improved range and signal strength are beneficial.

• Temporary or Portable Installations: The magnetic base and flexible spring design make it ideal for setups where the antenna needs to be moved or repositioned frequently.

• Placement: Ensure the magnetic base is attached to a clean, flat metal surface for optimal performance. The flexible spring design allows you to adjust the antenna's position to achieve the best signal reception.

• Cable Management: With a 3-meter RG174 cable, manage the cable to avoid physical stress on the connectors and ensure it does not create interference or signal loss.

• Connector Compatibility: Verify that the SMA male connector is compatible with your device's antenna port to ensure a secure connection.
