## 1. Introduction 

The Barracuda OMB.915.B05F21 is a fiberglass omnidirectional outdoor antenna, operating in the 915MHz ISM band and is designed to offer long distance coverage. The antenna is designed for applications such as metering, industrial & environmental monitoring, remote asset monitoring and mesh network applications. The 915MHz band is one of the most widely used license free ISM bands. Typical applications are in SigFox, Helium, LoRa and LPWA networks. 

With a 5.9dBi peak gain, the OMB.915.B05F21omnidirectional 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 and a pole-mount and wall-mount bracket is included. This antenna is an ideal product for developing your own Helium Network on the 915MHz spectrum. 

Custom antenna modifications are subject to possible NRE and minimum order quantity. For further information please contact your regional Taoglas customer support team.
