The OMB.433.B06F21 is a 6dBi fiberglass omnidirectional outdoor antenna, operating in 433 MHz ISM band. The antenna is designed for applications such as metering, industrial/environmental monitoring, remote asset monitoring and mesh network applications. The OMB.433 operates at 433MHz, one of the most widely used license-free ISM bands, with a 6dBi peak gain. The omnidirectional antenna radiates uniformly in the azimuth providing coverage over long distances.

Coupled with a very low VSWR, this characteristic provides the best performance because the antenna gives maximum coverage range in the horizontal plane over 360 degrees, thus minimizing the number of nodes needed for a mesh network. The UV resistant fiberglass housing enables the OMB antenna to be utilized in all kinds of harsh environments, making it more robust and safer than traditional whip antennas. It can be connected directly to the access point or telemetry unit or can be mounted on the wall or device surface via the N-type connector. A smaller model, OMB.433.B03F21, with 3dBi peak gain, is also available.
