In 2018, practical broadcasting of 4K/8K ultra-high-definition television will start with 12-GHz band satellite broadcasting using right-and left-hand circular polarization in Japan. For 4K/8K satellite broadcasting reception, the Association of Radio Industries and Businesses standardized specifications of distribution equipment for home use. Therefore, we fabricated a dual-polarization receiving antenna and optical distribution equipment in accordance with the specifications. We measured the

We also confirmed that the fabricated optical distribution equipment was able to deliver 50 modulated signals with C/N degradation of 0.1 dB.
