Spurious Emission Measurements of Common Site Fm Transmitter Installations Using Separate Co-Located Antenna Systems

When two or more FM broadcast transmission systems share a cominon site with co-located antenna systems a degree of cross-coupling can occur between the systems. When this cross-coupling becomes excessive the transmitter final amplifiers can produce out-of-tolerance, non-harmonic related emissions....

Summary:When two or more FM broadcast transmission systems share a cominon site with co-located antenna systems a degree of cross-coupling can occur between the systems. When this cross-coupling becomes excessive the transmitter final amplifiers can produce out-of-tolerance, non-harmonic related emissions. The frequencies, and amplitudes of these emissions are related to the frequency, and amplitudes of the cross-coupled transmission systems.
