Earth stations for Television Receive Only (TVRO) are susceptible to in-band interference from terrestrial common carrier microwave links, out-of-band transmissions such as radar, and spectral noise.
The effects of interference can be minimized or eliminated by proper application of filters in the microwave and/or intermediate frequency signal paths. The proper selection of filters for a system will depend upon the nature of the interference and the effects of the offender on amplifiers and detectors.
