The shell has a connecting section connecting a first lateral surface section and a second lateral surface section. At least a portion of the first lateral surface section extends into the hole. The second lateral surface section extends away from the top surface of the base. The connecting section is disposed between the top surface of the base and a portion of the fastener. The connecting section has a first section and a second section, and the first section has a non-linear cross-section. The apparatus further includes a washer disposed between the portion of the fastener and the connecting section, and a portion of the washer engages the first section of the connecting section.

Abstract: Band rejection filters are protected from the adverse effects of external forces such as stresses, strains and vibrations from external loads and winds by utilizing a protective frame and dampers.

Abstract: Difficulties in grounding a non-integral, deep drawn resonator (DDR) to the filter body of a cavity may be substantially eliminated by preventing the movement of the DDR away from a grounding contact area on the filter body. The addition of a compression plate and stop limiter in the connection of the non-integral DR to the filter body helps insure that any such movement is eliminated or substantially reduced.

Abstract: Multi-conductor cables for telecommunication systems are disclosed. One multi-conductor cable may include a plurality of fiber-optic conductors and/or power conductors extending within an outer jacket in a main body portion of the cable, and extending outside of the outer jacket in a break-out portion of the cable. A break-out boot may be attached to the outer jacket and may surround the conductors in a break-out portion of the cable. Potting material may be provided in the break-out boot within spaces between adjacent conductors to provide innovative sealing of the break-out portion.

Abstract: Orthomode transducers (OMTs) and methods of fabricating OMTs are disclosed. According to disclosed embodiments, an OMT includes a housing defining an internal waveguide. The housing may be composed of a first cast housing member attached to a second cast housing member. The first housing member may include a first side of the waveguide that is cast into the first housing member. The second housing member may include a second side of the waveguide that is cast into the second housing member. A method of fabricating an OMT may include arranging at least one casting insert in at least one mold, casting the housing in the mold and casting a waveguide in the housing using the at least one casting insert. The disclosed devices and methods provide cost effective solutions for fabricating OMTs of various operating frequencies that share a substantially similar outer housing shape and size.

Abstract: Sealing portions of an orthomode transducer or another antenna component is accomplished by forming first and second receptacles or channels in one half or portion of the transducer and inserting first and second type of compressible sealing components into the receptacles. Upon attaching additional portions of the transducer the compressible sealing components may be compressed, but the compression is limited to an amount within a compression range to maintain a seal.

Abstract: An assembly and method relates to stabilizing a radio frequency (RF) filter with respect to a housing. The assembly can include a filter component; a housing having a groove to receive the filter component; a cover mounted to the housing to cover the groove; and an elastomeric element disposed between the cover and the filter. The elastomeric element may be one or more tubular pieces.

Abstract: Various embodiments relate to a base station element and related method of suppressing an alternating-current (AC) portion of a signal. A base station element includes a filter capable of lightning suppression through the use of an LC filter that suppresses an AC portion of a received signal while passing a DC portion of the signal. The LC filter includes a flat inductor disposed in a cavity of the base station. The flat inductor may be connected to other electrical components disposed in the cavity of the base station to complete the electrical circuit. In some embodiments, the flat inductor may be produced from one material through photo-etching and may also include snap in or snap on connectors on one or both ends to enable galvanic contact with other components like a tap pin or a printed circuit board (PCB) without requiring attachment through soldering.

Abstract: A cavity filter has a resonator. The resonator is engaged by a rod having a mounting portion and a thermal dissipation portion. The mounting portion of the rod extends through the floor of the cavity filter to engage an internal surface of the resonator. The thermal dissipation portion dissipates heat from the resonator to the outside of the cavity filter.

Abstract: Various exemplary embodiments relate to a temperature compensation structure for use in a dielectric resonator that permits a support to be thermally efficient in rapidly transferring heat generated by a central puck in the resonator. The temperature compensation structure may have an extension shaped to promote heat from the puck into the support, thereby permitting high power operation of the dielectric resonator without overheating.

Abstract: Communications connectors communicatively and physically join a plurality of network elements. Communications connectors are substantially flangeless so as to provide a substantially continuous surface between the connector and network elements joined thereto. Communications connectors may include or be modified with a grounding surface or a seating member. Communications connectors include a variety of communicative contact surfaces and joining mechanisms, including those compatible with known 7/16 DIN connections. Methods include installing network elements to connection interfaces on connectors without the use of a flange or other exterior part. Methods optionally include applying an adhesive to connection interfaces to provide a breakable, locked connection between network elements and connectors.

Abstract: Various exemplary embodiments include a cavity having a tuning assembly with tunable capacitive coupling. The tuning assembly may have a recess having a specified depth, designed for a default magnitude of coupling into the cavity. A sleeve may be fully inserted within the recess to have the structure operate at that default coupling magnitude. If a different amount of coupling is desired, the sleeve may be inserted to a particular depth that only includes part of the recess, enabling repeatable tuning of a plurality of cavities.
