1.Introduction

The OMB.433.B03F21 is a fiberglass Omni-directional outdoor antenna, operating in

the 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 3dBi peak gain. The omni-directional antenna radiates uniformly in the azimuth.

This collinear design characteristic provides the best performance, giving optimized

coverage and therefore longer range in the horizontal plane over 360 degrees, thus

minimizing the amount 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 wall or device surface via the N-type connector.

Another larger model, the OMB.433.B06F21 with 6dBi peak gain, also working in the

433MHz ISM band, is also available. Gain and connector customizable, subject to

MOQ.
