SHARING THE UHF BETWEEN SPACE AND TERRESTRIAL SERVICES

Abstract

The UHF is the choice portion of the spectrum for these satellite relay services from the standpoints of both the satellite relay performance and the total systems costs (the latter being dominated by the total costs of the many small earth terminals). It appears to be entirely feasible for the UHF to provide double duty with its complete sharing reuse for the new highest quality space services, without hindering the current terrestrial services or limiting their future development. The most difficult case of the sharing between the two types of TV broadcast service was examined in detail, and although there are many unknowns remaining, it appears that sharing will be feasible with adequate margins using earth terminals with as small receiving antennas as 1-sqm effective area.
