Potential Interference from Terrestrial Sources into Direct Broadcast Satellite Home Receiving Systems

Potential interference sources into direct broadcast satellite (DBS) home receiving equipment and the means of reducing the effects are discussed in this paper. Interference sources are divided into two categories: those that enter at the receiving antenna microwave equipment, and those that enter at the indoor unit or at the coaxial cable connecting the antenna to indoor equipment. The results of the analysis show that good design practice will control this kind of interference to an acceptable degree. Recommendations to reduce the interference are given.
