Abstract:
A satellite broadcast receiving outdoor converter comprising:a waveguide in which the broadcast electric wave travelling therein travels as a first TE11 mode linearly polarized wave and as a second TE mode linearly polarized wave intersecting at a right angle with each other;a first probe for detecting said first linearly polarized wave, disposed at a predetermined position within said waveguide;a first reflecting conductor for reflecting said first polarized wave, disposed approximately 1/4 of the wavelength of said broadcast electric wave from said first probe in the direction in which the electric wave travels;a second probe for detecting said second linearly polarized wave, disposed in the neighborhood of said first reflecting conductor; anda second reflecting conductor for reflecting said second polarized wave, disposed approximately 1/4 of the wavelength of said broadcast electric wave from said second probe in the direction in which the electric wave travels;an electrically conductive columnar portion erected on said second reflecting conductor so that said electrically conductive columnar portion lies in the neighborhood of the inner peripheral surface of said waveguide in parallel to the axial line thereof.
