Abstract

PURPOSE:To promote the reliability, by reducing the influence of switch when short circutting, by using a short circuit, open type switch in antenna switching device to be used for a satellite loading use, thereby selecting the length of electricity between a distributor and the switch by 1/4 wavelength.
