High gain antennas, sensitive receivers and high power transmitters which are used at the earth stations of space communications systems complicate the problem of sharing frequencies with other surface services. However, because of the dependence of beyond-the-horizon tropospheric propagation on the scattering angle, it is possible to offset the gain of the terminal antenna by elevating the beam. Early studies of frequency-sharing assumed that the beam of the earth station was elevated 'sufficiently' to increase the transmission loss to that which would be obtained if the actual antenna were replaced by an isotropic antenna. This paper studies the question of what constitutes a 'sufficient' elevation angle, as described above, for the particular conditions of a smooth earth, 30-foot antenna heights and several combinations of antenna sizes. Some results are also given when there is an elevated horizon at the earth terminal end of the path.

The treatise summarizes a preliminary study of antenna beam shaping potential and/or limitations, as applied to sharing of available frequency bands between satellite and terrestrial systems. Two different aspects are discussed: Low energy levels outside a certain 'spot' region on the earth, and rapid decay at the boundary of the region. These are performance characteristics generally related to antenna configuration and design. Not discussed is the problem of over and under illumination of oddly shaped geographical areas. (Author).
