1. Introduction The Meteor FW.81 is a 0dBi 135MHz ISM band 1/4 wavelength monopole flexible whip antenna with omni-directional pattern optimized in the azimuth for wide coverage range in typical 135MHz applications such as Wireless M-Bus metering. It is also used in remote asset monitoring applications, alarms, paging systems and private mobile radio services. The Meteor has a IP67 housing. The 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. TNC and N-type antenna versions are also available. 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. Customized frequency and gain versions can be supplied. SPE-12-8-034/C/PK Page 2 of 6
