Abstract
An antenna housing functions as a radome for a satellite antenna device for mounting on a moving body. The housing includes a lower portion on which the antenna device, having an antenna body and an automatic tracking mechanism, is fixedly mounted and an upper portion releasably connected to the lower portion in a watertight manner. The upper portion is made of a dielectric material and composed of a single layer of a resin having a relative dielectric constant of no more than 2. The upper portion is spaced from a surface of the antenna body by a distance except for values close to an integral multiple of a half-wave length.
