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

The 433MHz 3dBi Spring Magnetic Antenna is a more modestly powered antenna suitable for various wireless applications. Here’s an overview of its features and typical uses:

1. Frequency Range: Operates at 433 MHz, which is common for short-range wireless communication, such as remote controls and some IoT devices.

2. Gain: The 3dBi gain provides a basic level of signal enhancement compared to standard antennas. This moderate gain helps improve signal reception and transmission within a relatively short to moderate range.

3. Spring Design: The spring construction allows the antenna to be flexible and durable. It can bend and absorb some physical stress without breaking, which is beneficial in environments where the antenna might be subject to movement or vibration.

4. Magnetic Base: Equipped with a magnetic base for easy attachment to metal surfaces. This is useful for temporary setups or where permanent mounting is not practical. The magnetic base allows for simple repositioning.

5. Omnidirectional Pattern: Generally, this type of antenna has an omnidirectional radiation pattern, meaning it transmits and receives signals in all directions. This characteristic is useful when the orientation of the antenna might vary.

• Remote Controls: Ideal for devices such as garage door openers or key fobs, where a moderate range and reliable connection are needed.

• Wireless Sensors: Suitable for short to moderate-range sensor networks used in home automation or small-scale industrial applications.

• IoT Devices: Works well for Internet of Things (IoT) applications where devices are close to each other and don’t require long-range communication.

• Amateur Radio: Can be used by amateur radio operators for applications where high gain is not crucial but flexibility and ease of installation are beneficial.

• Telemetry Systems: Useful in scenarios where you need basic signal enhancement without the need for high gain.
