A high frequency coaxial line coupling device which is insertable along the length of a coaxial line such as that which connects a rotary antenna carried on a moving body such as vehicle or vessel to receive a signal from a communication or broadcast satellite, with a receiver component such as tuner fixed to the moving body, for the purpose of allowing free relative rotation of the two segments of the coaxial line separated by the coupling device and preventing twist or entanglement of the coaxial line caused by rotation of the antenna with turning movement of the moving body. The device structure provides for a low transmission loss characteristic over a wide frequency range.
