2. Description of the Related Art A feeder line is a cable for transmitting a signal received by an antenna (antenna) to a receiver or a signal sent from a transmitter to the antenna. The feeder line is a parallel two-wire cable or a coaxial cable. , A waveguide, etc., which are known to be used by being distinguished by the frequency of a signal.

Since the work for laying and wiring the power supply line is carried out at a high place, for example, at a high place such as a steel tower, or in an unstable working environment, the work can be performed while being restricted in workability and safety. It has to be advanced.

The power supply line is supported and fixed by a support fastening structure so that the power supply line is supported and fixed by inserting and inserting synthetic rubber having oil resistance, for example, a collar made of Neoprene under the trade name, at a preset location. It is well known that what is supported and fixed is called a supporting metal on the spot, and there is a type adapted to the type of the feeder line to be supported. In the present specification, this support metal piece is referred to as a support fastening member.
