  • Patent number: 10429423
    Abstract: A PIM probe that includes a PIM antenna carried on a wand sized for positioning by hand. The PIM antenna is tuned by loop size to receive PIM corresponding to uplink reception channels of a site antenna generated by downlink broadcast frequencies F1 and F2 of the duplex antenna. The PIM antenna vanes may include conductors printed on a PC boards or wire loops. A PIM probe system includes a signal analyzer that displays a representation of PIM received by the PIM antenna. The PIM probe system further includes an RF filter for passing the PIM frequencies of interest and suppressing the test frequencies transmitted by the site antenna, such as a cellular base station antenna. When the site antenna is broadcasting the test frequencies, the technician places the PIM antenna in various locations to detect the presence of PIM in those locations.

  • Patent number: 5844529
    Abstract: An enclosed antenna assembly having a non-rigid, floating connection between an aluminum tray and a radome along the length of the assembly. The non-rigid, floating connection along the length of the antenna assembly provides a seal that is not damaged or degraded as a result of thermal expansion and contraction of the dissimilar materials. The tray and radome are joined along their length by a tongue and groove type connection, which allows free movement along the major axis. A top end cap provides the only rigid connection between the tray and the radome. A bottom end cap is fastened only to the radome. The design of the keyway and the top end cap prevent direct water intrusion. The bottom end cap includes weep holes to allow condensation to escape from the interior of the antenna assembly.
