    Abstract: The present application is directed to a mounting system for a base station antenna. The system includes a passive antenna and an active antenna module and a mounting kit. The mounting kit includes an upper radio mounting bracket assembly and a lower radio mounting bracket assembly, and is configured to mount and secure an upper portion of the passive antenna to a mounting structure and mount and secure the active antenna module to the mounting structure behind the passive antenna. The system further includes a middle antenna mounting bracket assembly configured to pivotably mount a middle portion of the passive antenna to the mounting structure and a lower antenna mounting bracket assembly configured to slidably and/or pivotably mount a lower portion of the passive antenna to the mounting structure. The mounting system is configured to adjust the base station antenna downwardly or upwardly to a desired angle of tilt. Mounting kits and methods of operating same are also described herein.

    Abstract: According to methods of performing measurements to determine a distance to a passive-intermodulation (“PIM”) source, a first RF signal comprising a first frequency and a second RF signal comprising a second frequency may be applied to a device under test. A reference signal comprising a higher-order intermodulation-product of the first frequency and the second frequency may also be generated. An output signal from the device under test and the reference signal may be digitized and a calibration measurement may be applied. A phase difference between the device under test output and the reference signal may be determined. A plurality of phase differences may be determined for multiple first frequencies, and from the plurality of phase differences, a delay may be calculated, which may be multiplied by the velocity of propagation on the medium connecting the device under test to the test equipment to determine a distance to the PIM source.
