<p>PROBLEM TO BE SOLVED: To hold a feeder line stably and protect it from the influence of the weather by inserting the feeder line in a pipe through a hole formed in part of the pipe and then passing it through the pipe. SOLUTION: In a pipe 1 for TV antenna, holes 3 large enough to allow a feeder line 2 to pass through are formed in parts of the pipe 1. The feeder line 2 is inserted into the pipe 1 through one of the holes 3 and then is passed through the pipe 1 and then is taken out through another hole 3 formed in a lower part of the pipe 1 to be connected to a TV. At that time, each hole is provided with a packing 4 and caps are mounted on the upper and the lower end of the pipe 1 respectively to prevent the intrusion of rain water or other matters into the pipe 1. By this method, the feeder line can be held stably and is protected from the influence of the weather and thereby unexpected accidents caused by strong wind or other troubles can be prevented.</p> |
