A cable coupler between a trunk cable having a first center conductor and a first outer conductor and a second cable having a second center conductor and a second outer conductor. An aperture is formed in the first outer conductor; a probe having a capacitive element on a first end is inserted into the aperture to contact the first center conductor. A second end of the probe is coupled to the second center conductor. The first outer conductor and the second outer conductor may be coupled together directly or via a second capacitor. A cover may be added to secure the different components and or to provide environmental protection for the cable coupler. The capacitive element may be mounted on an insulating substrate. A range of capacitive elements may be used to achieve a desired coupling between the trunk cable and the second cable.

Low loss cable coupler

A method and apparatus for forming a cable tap for coupling a co-axial trunk cable having a trunk outer conductor, to a tap cable. A channel is formed in the trunk outer conductor; a first tap conductor is coupled to a first side of the channel; and a second tap conductor is coupled to a second side of the channel. Alternatively, a trough may be formed and a conductor coupled with one end of the trough inserted. A fixture with an aperture for guiding a cutting tool to form a desired channel or trough may be supplied in a kit.

Shield slot tap

A method and apparatus for forming a cable coupler for coupling a co-axial trunk cable having a trunk outer conductor, to a coupler cable. A channel is formed in the trunk outer conductor; a first coupler conductor is coupled to a first side of the channel; and a second coupler conductor is coupled to a second side of the channel. Alternatively, a trough may be formed and a conductor coupled with one end of a conductor inserted in the trough. Channels or troughs may be pre-formed in a trunk cable creating coupler connection points that may be quickly adapted to form a coupler with minimal field installation requirements. The coupler coupling factor may be varied by electrically shortening the channel or trough with, for example, a conductive ring, conductive foil or a conductive collar.

Method and apparatus for shield slot signal coupler

An omnidirectional microwave antenna comprises a paraboloidal reflector disposed above the ground and facing downwardly with a substantially horizontal aperture and a substantially vertical axis. A vertically oriented feed horn is located below the paraboloidal reflector on the axis of the paraboloidal reflector and has a phase center located near the focal point of the paraboloidal reflector. A conical reflector having a shaped reflecting surface defined by the parameters of a mathematical equation extends downwardly away from the periphery of the feed horn for reflecting radiation received vertically from the paraboloidal reflector in a horizontal direction away from the conical reflector, and for reflecting horizontally received radiation vertically to the paraboloidal reflector. A radome extends downwardly from the outer periphery of the paraboloidal reflector and includes an absorber material for absorbing radiation propagated laterally from the feed horn and the conical reflector above the aperture of the feed horn.
