To provide a base which enables an antenna unit to be easily and strongly mounted on a counterweight.SOLUTION: A base is mounted on a counterweight in an upper turning body of a construction machine. The base includes a substrate, a pedestal and a support plate. The substrate is mounted on an end on a vertical upper side of a recess recessed toward a rear side of the upper turning body of the counterweight, and blocks an opening opened toward the vertical upper side in the recess. The pedestal is formed on a surface facing the vertical upper side of the substrate, and is installed with an antenna unit from the vertical upper side. The support plate projects to the vertical lower side from the substrate, and is connected to a bracket projecting to a front side of the upper turning body from the bottom part of the recess in the counterweight in a state of being restrained to the bracket.SELECTED DRAWING: Figure 6

    【課題】アンテナユニットをカウンタウエイトに容易かつ強固に取付け可能にする基台を提供すること。【解決手段】基台は、建設機械の上部旋回体において、カウンタウエイトに取付けられる。基台は、基板、台座及び支持板を備える。基板は、上部旋回体の後方側へ向かって凹むカウンタウエイトの凹部の鉛直上側の端に取付けられ、凹部において鉛直上側に向かって開口する開口を塞ぐ。台座は、基板の鉛直上側を向く表面に形成され、鉛直上側からアンテナユニットが設置される。支持板は、基板から鉛直下側に突出するとともに、カウンタウエイトにおいて凹部の底部から上部旋回体の前方側へ突出するブラケットに対して拘束された状態で、ブラケットに接続される。【選択図】図6
