Abstract (in Japanese) (See Japanese page) 
(in English) Test UHDTV satellite broadcasting was started on August 1st, 2016. In 2018, practical UHDTV satellite broadcasting will be provided by using the right- and left-hand circular polarization in the 12-GHz band. For satellite broadcasting reception, a low noise block converter of a receiving antenna converts the 12-GHz band receiving signals to the intermediate frequency (IF) and the IF signals are transmitted with coaxial cables or optical fibers. Therefore, ARIB STD-B63 standardized the left-hand circular polarization IF (2224.41 to 3223.25 MHz), whose frequency is higher than that of the currently used IF (1032.23 to 2070.25 MHz). Because the left-hand circular polarization IF band overlaps with the 2.4-GHz band wireless LAN system, it is important to evaluate the shielding effectiveness of coaxial cables when we transmit the IF signals on a coaxial cable. Hence, we measured the coaxial cables and obtained the shielding effectiveness of 90 to 110 dB in 2 to 3 GHz. From this result, we showed the possibility of the frequency sharing of the IF system and the wireless LAN system.
