Systems and related methods for reducing passive intermodulation (PIM) include a combination of an antenna control unit (ACU) and a remote electrical tilt (RET) system. The ACU may be used to generate rotational motion of an output drive shaft in response to an input tilt control signal. The RET system couples to the output drive shaft of the ACU and may be used to convert the rotational motion into translational motion for modifying a phase shift of an antenna beam. PIM may be substantially eliminated by providing electrical isolation between the ACU and RET system in the form of a non-conductive connector that engages the draft shaft of the ACU.

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.

A cavity filter includes a threaded resonator and a threaded filter body to improve the coupling of radio frequency signals.

Methods and devices for connecting a resonator to a filter body

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.

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.

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.

Various exemplary embodiments relate to an improved coupler for resonant cavities and dielectric resonators. The coupler may permit accurate tuning of electromagnetic signals within desired frequency ranges. The coupler may be secured to a movable tuning device by a plurality of securing members. Each securing member may be separate, having no contact with any other securing member.

A tray for use with a barbecue having one or more griddles partly or wholly outlying or able to outlie the base of the barbecue wherein the tray is locatable beneath the griddles or the parts of griddles outlying the base to direct fat falling therefrom to the base is described. The tray is particularly suitable for use with multi-level hooded barbecues.
