1. A method of locating antenna problems in a radio frequency communications network including a plurality of cell sites, each of said cell sites comprising at least one sector having an antenna associated therewith and further having associated therewith a base station (“

  • BS”

    ) comprising a site test mobile (“

    STM”

    ) connectable to said antenna, all of said base stations being interconnected by a base station controller (“

    BSC”

    ), the method comprising;

    selecting one of said cell sites;

    selecting a sector of said selected one of said cell sites;

    identifying a neighbor cell site and sector for said selected cell site and sector;

    determining whether said communications network has been calibrated;

    if said communications network has not been calibrated, calibrating said communications network;

    if said communications network has been calibrated, automatically taking a plurality of measurements with respect to said selected cell site and sector and said neighbor cell site and sector, said measurements being stored in a second lookup table in a centrally located database of said communications network and updated in real time;

    automatically comparing said plurality of measurements with calibration data for said selected cell site and sector and said neighbor cell site and sector, said calibration data being stored in a first lookup table in the centrally located database of said communications network; and

    automatically determining from said comparison whether said antenna suffers from at least one predefined problem.
