摘要： A system for increasing isolation between analog and digital antennas suited for FM IBOC operations is provided, wherein an interleaved combination of dissimilar antennas are arrayed with an offset there between to obtain a desired performance the use of dissimilar antennas and an offset, several additional degrees of freedom are afforded to the broadcaster in obtaining the desired isolation between signals, and also for upgrading an existing analog system to IBOC capability.
