PC240.09.0300K Antenna Low-Profile ISM, LoRa 433MHz adhesive/screw mount MMCX(M) RA 30cm for Wireless Alarm Devices, Home Security & Alarm, Home Automation, Metering

This 433MHz embedded omni-directional antenna is designed for reliable ISM-band links in compact devices. Its helical dipole structure helps maintain strong performance in a small footprint, while the integrated LC tank balun helps reduce sensitivity to cable routing and cable length changes.

Ideal for systems that need stable 433MHz performance inside enclosures, including wireless alarm devices, home security & alarm, home automation, metering, remote control, and industrial control.

• Compact embedded form factor: Low-profile PCB-style antenna designed for integration into devices
• Stable in real installations: LC tank balun helps mitigate detuning from cable routing variations
• Flexible mounting options: Can be attached to device housings using adhesive or secured using screw mounting holes
