This is a fiberglass omni-directional outdoor 433MHz high gain antenna is designed for appliations such as metering, industrial monitoring, environmental monitoring, remote asset monitoring and mesh network applications.
This antenna operates at 433MHz which is one of the most popular used license-free ISM band with 3dBi high gain. This omni-directional antenna radiates uniformly in the azimuth. The internal collinear characteristic provides one best performance and long-range 360 degree coverage, which can minimize the amount of nodes needed for a mesh networks.
