Definitions

  • I have also shown a pair of lines lines and, more particularly, to a means for couadapted to be fed in a push-pull relationship, pling a single line to a push-pull line or a pair one of said lines being composed of an outer of transmission lines operating in a push-pull sheath 8 and an inner conductor 9, and the other a relationship. being composed of an outer sheath ii] and an 5
  • An object of the present invention is to proinner conductor I I.
  • the inner conductor 9 is vide a junction between a single and a pushdirectly connected to inner conductor 1 and is, pull line. therefore, energized in the same relationship as Another object of the present invention is to the conductor 1.
  • Means for coupling a single concentric line having an outer sheath and an inner conductor to a push-pull circuit having a pair of conductors adapted to be energized in an opposing phase relationship comprising a connection from said inner conductor to one of said pair of conductors, a connection from the end of said outer sheath to the other of said pair of conductors and an outer shell surrounding the end of said single line and its junction with said pair of lines, said shell-being connected to said outer sheath at a distance equal to a quarter of the length of the operating Wave from the end of said sheath, and a balancing circuit including an inner conductor having a diameter equal to the diameter of the outer sheath of said single line connected to the inner conductor of said single line and an outer shell having a diameter equal to the diameter of said first outer shell and connected thereto, the inner conductor and outer shell of said balancing circuit being connected together at a distance equal to a quarter of the length of the operating wave from said connections.
