Coil Loaded Antenna 433Mhz helical antenna applications
The 433 wireless module has low power consumption and powerful functions. It is widely used in robot control, smart homes, wireless meter reading, and other fields. The product is an industrial-grade design and is suitable for outdoor harsh environments.
When the module finds that the distance is not enough during use, it is usually recommended to select a suitable antenna to achieve the purpose of increasing the communication distance.
Which antenna is used for the 433 MHz wireless modules?
What kind of antenna is good for 433 MHz wireless modules and what matters should be paid attention to when installing the antenna?
The antenna is an important part of the communication system. Its performance directly affects the indicators of the communication system. When choosing an antenna, you must pay attention to its performance.
In addition, the antenna gain is one of the important indicators of the antenna, which is the directivity and efficiency. The product is the performance of the size of the antenna radiated or received.
Generally, the commonly used wireless module requires an antenna impedance of 50 ohms. The 433MHz wireless modules can use a general 433MHz spring antenna, folded/straight rubber duck antenna, suction cup sucker antenna, etc.
These antennas are dedicated antennas designed for 433MHz wireless communication systems. The antennas have good standing wave ratio performance.
Besides the Coil Loaded Antenna RF 433MHz Spring Antenna, C&T RF Antennas Inc supplies the spring helical antenna with other frequency bands such as 315 Mhz, 433 Mhz, 868 Mhz, 915 Mhz, Wifi, GSM, etc.
