receptacle to the coaxial cable 6 of FIG. FIG. 5 is a side view showing the coaxial cable mounting
device of FIG. In FIG. 1, 11 is a cover for covering the coaxial cable attachment mechanism
described later, 12 is a chassis to which the coaxial cable attachment mechanism is attached, and
the cover 11 is attached to the chassis chassis 12 by a screw lla. Also, the chassis 12 is formed
with an opening 12a for inserting a coaxial cable or a BNC receptacle. As shown in detail in FIG. 2
and FIG. 4, the reference numeral 13 is a mounting bracket which is roughly composed of two
horizontal portions and a vertical portion connecting the two horizontal portions, and is a
mounting bracket having a stepped cross section. At the center of the vertical part of the
mounting bracket 13 and the horizontal part of the upper stage, the braided wire 20b of the
