sp e - 15 - 8 - 011/a /wy page 2 of 15 1. introduction the pc240.09.0300k is a 433mhz embedded omni - d irectional 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 device s . 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 pc2 40.09.0300k uses a lc tank balun circuit. the lc tank balun circuit stabil iz es the electrical characteristics when cable length changes. please refer to application note (s ection 7) for more details. the pc240.09.0300k is designed as a helical dipole structure, which can significantly shorten the length while maintaining high efficiency. users can easily attach the antenna on their device housing via the 3m adhesive, with ou t worrying about their housing detu ning the antenna as it has been tuned on a 2mm thick abs board , which is typical enclosure thickness and material for electronic devices . it also has four thru holes that users can fix the antenna with screws . w ith the b alun circuit and helical dipole design, the pc240.09.0300k is truly a miniature 433 mhz pcb antenna , whic h can provide worry - free cable routing during installation .

sp e - 15 - 8 - 011/a /wy page 14 of 15 8. installation reco mmendations pc240 antenna is a resonant arm meander ed non - standard dipole novel antenna design. however , it still keep s the same radiation characteristics as standard dipole antenna s. it has an omni - directional radiation pattern in the h - plane(2d yz pl ane in the spec ). the installation recommendation of this antenna is mounting the antenna internally on the side walls of the device, with one of the arms of the t pointing downwards for either of the antenna installation s shown above, the anten na will exhibit the radiation pattern as shown below.
sp e - 15 - 8 - 011/a /wy page 15 of 15 orange means much higher antenna gains, green means the weakest antenna gains. so the correct application of this antenn a is to let the antenna edges as below face the sky and earth. t hen the antenna can have omni - directional radiation pattern s that are horizontal to the earth.
