Imp in collaboration with antenna

This Delock ISM 433 MHz antenna is designed for receiving and transmitting radio signals in 433 MHz wireless communication applications. The antenna is used for both indoor and outdoor applications where an external antenna with magnetic mounting is desired. The version with an SMA male connector, an omnidirectional radiation pattern, and a gain of 3 dBi is suitable for use within ISM 433 MHz systems. This allows the antenna to be used with wireless sensors, remote controls, and industrial communication systems. The antenna is equipped with a magnetic base and an RG-174 coaxial cable, which allows flexible placement on metal surfaces.
