Amplified Wireless Repeater

The KET-RMB-220, together with the nodes with integrated repeater functionality and the Gateway, provides the network infrastructure necessary for the proper transmission of data collected by wireless sensors.

The X-Monitor technology guarantees high reliability and resistance to interference, while the excellent sensibility of the radio module allows to reach distances of more than 1000 m in free air.

Standard antenna connector, supports antennas with 90° joint.

Thanks to the increased power, this device reduces the overall number of nodes in the network.
