Antenna for 433 MHz ISM band

16 May 2018 Telecoms, Datacoms, Wireless, IoT

The OMB.433.B03F21 antenna for metering, industrial and environmental monitoring operates in the 433 MHz ISM band, one of the most widely used licence-free ISM bands, with a 3 dBi peak gain. Made by Taoglas, the fibreglass outdoor antenna is omnidirectional and radiates uniformly in the azimuth, and is suitable for remote asset monitoring and mesh network applications.

The collinear design characteristic provides enhanced performance, giving optimised coverage and therefore longer range in the horizontal plane over 360 degrees, thus minimising the number of nodes needed for a mesh network. The UV resistant fibreglass housing enables the OMB antenna to be utilised in all kinds of harsh environments, making it more robust and safer than traditional whip antennas. It can be connected directly to an access point or telemetry unit, or can be mounted on a wall or device surface via the N-type connector.

Another larger model, the OMB.433.B06F21 with 6 dBi peak gain, also working in the 433 MHz ISM band, is also available. Gain and connector are customisable, subject to minimum order quantity.
