The FW.81 (Meteor) is a 0dBi, 135 MHz ISM band 1/4 wavelength monopole flexible whip antenna with omnidirectional pattern optimized in the azimuth for wide coverage range in typical 135 MHz applications such as Wireless M-Bus metering. Other uses include remote asset monitoring applications, alarms, paging systems, and private mobile radio services. This antenna, like all low-frequency monopole antennas, needs to be mounted to a metal plate to radiate. For a waterproof integration to a metal box a waterproof panel-mount SMA connector or cable assembly can be provided. This whip is made up of a flexible inner steel core covered by TPU so extremely resistant to collisions and maintaining its original shape and RF performance.
