4PCS, 433MHz 18cm antenna

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
18 cm antenna designed for wireless systems and radio modules operating at 433 MHz. The antenna is suitable for use with 433 MHz transmitter and receiver modules using ASK or OOK.

The 18 cm length is close to a quarter wavelength antenna for 433 MHz, making it suitable for use in the 433 MHz ISM band. It can for example be used with radio modules such as SYN115, SYN480R, SYN470R and similar 433 MHz modules.

The antenna can be used as a simple wire antenna and connected directly to a suitable antenna connection on the radio module. For best range, the antenna should be positioned as freely as possible away from the ground plane, circuit board and other conductive objects.

Suitable for hobby electronics, remote controls, sensors, alarms, wireless switches and other projects using 433 MHz radio communication.
