In the olden golden days building the MCI route with full block systems, we would have "bucks" or "bumps" in frequency plans when required, and we learned first hand how important it was to use ultra high performance antennas or better in such situations. With very little free space loss, antenna performance is key and there is very little reliable data on close-coupling antenna performance, so it is extremely difficult to accurately calculate expected interference levels in these situations. With the prevalence of 2&3' antennas these days, antenna isolation will be an even larger challenge.
