The PC240.09.0300K is a 433MHz embedded omni-directional adhesive / screw mounted, linear polarised, dipole antenna with high efficiency at only 96mm in length. The antenna was specifically designed for use in wireless alarm devices. It operates in license-free ISM band, making the PC240.09.0300K a suitable antenna in systems such as home security & alarm, home automation, metering, remote control, industrial control, and other 433MHz applications. Most low frequency antennas detune inside enclosures when the cable is moved to new orientations. In order to mitigate the influence of cable routing direction while installing, the PC240.09.0300K uses a LC tank balun circuit. The LC tank balun circuit stabilizes the electrical characteristics when cable length changes. Please refer to Application Note (Section 7) for more details.
