<P>PROBLEM TO BE SOLVED: To provide a device capable of easily mounting a rod antenna to a support pillar with a simple structure, and capable of retaining a stable mounting condition with less secular change. <P>SOLUTION: The mounting device includes: a mounting frame 3 which projects on a peripheral side of a rod antenna a substantially in a U-shape in a plan view; a support disk 1 which projects on a periphery side of a support pillar p; and a mounting metal fitting 4 interposed between the mounting frame 3 and the support disk 1. The mounting metal fitting 4 is composed of a horizontal surface plate 4a and side plates 4b, 4b erected opposite to both sides of the horizontal surface plate. The side plate 4b is placed on the horizontal surface plate 4a and connected to the mounting frame 3 with a connection bolt 15. An axial hole 13 through which an axial bolt 5 penetrates and an adjustment hole 14 through which an adjustment bolt penetrates are disposed on the horizontal surface plate 4a. An appropriate number of adjustment holes 14 are arranged in a concentric circle around the axial hole 13, and a first through-hole that is matched to the axial hole 13 and lets the axial bolt 5 penetrate and a second through-hole that is matched to any one of the adjustment holes 14 and lets the adjustment bolt 7 penetrate are arranged in a radial direction of the support pillar p on an upper part piece 1b of the support disk 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
