Engineered for diverse 433MHz receiving devices, this high-performance antenna ensures full compatibility with all 433MHz receivers, significantly improving signal reception sensitivity and transmission range. The system includes a 3-meter (9.8ft) coaxial cable with an SMA male connector, featuring a pure copper core for optimal transmission efficiency. Its compact design enables tool-free installation and direct device connectivity without adapters. Operating at 433MHz with 50-ohm impedance, the vertically polarized omnidirectional antenna excels in low-power applications such as garage door openers, garage door opener range extender, garage door opener signal booster, baby monitors, and smart home sensors. Designed for indoor/outdoor flexibility, the wall-mount bracket withstands extreme temperatures (-50°C to 70°C) while maintaining stable performance in all orientations.
