PROBLEM TO BE SOLVED: To provide the satellite signal distributer by which a reception signal of a desired polarized wave is transmitted through one cable to each terminal in the case of sending a reception signal from a satellite reception antenna that outputs the reception signal of vertically and horizontally polarized waves to a plurality of the terminals. SOLUTION: Reception signals of vertically and horizontally polarized waves received at input terminals 22V, 22H are distributed into four by distribution circuits 26V, 26H respectively and each of the 4-distributed signals is given to changeover circuits 28a-28d. Then each of the changeover circuits 28a-28d selects a vertically or a horizontally polarized wave signal depending on a voltage level (11V or 15V) of a polarized wave switching signal received from a terminal equipment connecting to output terminals 24a-24d and provides an output of the selected signal from the output terminals 24a-24d. Furthermore, the polarized wave switching signal (11V or 15V) is outputted to a reception section corresponding to the reception antenna from the input terminals 22V, 22H via a voltage synthesis section 30 and choke coils LV, LH, etc. |
