Abstract: An antenna rotator includes a housing having an access port disposed therethrough. Positioned within the housing and proximate to the access port is an interface connector. The interface connector provided by the housing is configured to be removably attached to a module connector provided by a detection module, which may include a sensor for detecting a position of an encoder that is rotated by a motor drive within the housing. As a result, the detection module, which is highly susceptible to electrical damage from lightning, can be conveniently accessed and replaced.

Abstract: A common-mode in-line radio frequency (RF) filter isolator includes one or more modules that incorporate a respective RF filter circuit. The one or more modules are configured to be electrically coupled in-line with a communication link, such as an Ethernet cable for example. Accordingly, the filter isolator device is enabled to reduce or eliminate the presence of common-mode noise that is present on the network communication link.

Abstract: A common-mode current suppression device, such as a balun and line isolator, includes a core formed of nanocrystalline material. The core may be formed in any desired configuration, such as a toroidal core, a sleeve core, a drum core, a rod core, or a binocular core. The use of nanocrystalline material allows the core to achieve increased common-mode impedance (CMI) that exceeds that achievable by cores formed of traditional ferromagnetic materials.

Abstract: A multi-core common-mode current suppression device (CMD), such as a balun and line isolator, includes at a pair of spaced cores. The cores may be separated by a spacer, such that in the case of a pair of toroidal cores, the axial centers of the cores may be arranged parallel to each other or coaxial with each other. Such a configuration allows the multi-core (CMD) to achieve higher levels of overall common-mode impedance (CMI) as compared to that of existing CMDs that utilize a stacked core configuration.

Abstract: Disclosed is a cable gripping device used for manually gripping a coaxial cable to install a coaxial connector on the coaxial cable. According to an exemplary embodiment, the coaxial gripping tool includes a first half portion and a mating and/or hinged second half portion, wherein the mating/hinged portions provide a longitudinal bore configured to grip the coaxial cable.

Abstract: A system is provided which carries cables isolated from each other and isolated from a tower which carries antennas for the cables. The system includes a support plate carried near the top of the tower which carries strain relief devices for gripping each cable. A plurality of guide plates are spaced along the tower and each plate carries inserts which provide apertures of a predetermined size to match the size of the cable passing therethrough. The apertures are spaced from each other and spaced from the tower. An additional plate is attached to the tower near the bottom thereof and is provided with connector assemblies so that the cables may be attached to a send/receive unit.

Abstract: A device is provided to attach a connector having an internally threaded base and external threads to a cable having a casing. The device includes a body having a bore therethrough. At least a portion of the bore is threaded and the external threads on the connector are threaded into the threads of the bore until a stop surface in the bore is engaged by a portion of the connector. The device may then be turned to thread the base onto the casing of the cable.

Abstract: A hybridized connector apparatus is provided for solder connection with a central conductor of an associated coaxial cable and for crimp connection with a conductive braid and foil of the coaxial cable, and includes a hollow, generally cylindrical contact pin member or tip portion operably received into an interior of a generally ring-shaped dielectric spacer disk. The dielectric is received into a connector body, which is received into a shell. An end of the contact pin member defines an interface portion having a substantially constant outer diameter D extending outwardly from the spacer disk beyond an extent of the body member in an insertion direction I. The interface portion defines a semicircular edge portion and may also include a linear edge portion disposed in a plane substantially oblique to the longitudinal axis, and a curvilinear edge portion.

Abstract: An antenna transmission line for feeding multiple items includes a first conductor member, a second conductor member, and a dielectric material positioned between the first and second conductor members, which prevents water from accumulating between the first and second conductive members. Means are provided to connect multiple elements to the transmission line at connection terminals. An insulator may be provided adjacent to each of the connection terminals, the insulator being generally non-conductive. A plurality of holes provided in the insulator on either side of the conductor members allows the elements to be weaved therethrough to provide a more stable connection.

Abstract: The present receive antenna interface for an RF (radio frequency) transceiver includes a transmitting and receiving antenna. The receive antenna interface also includes a relay and an electrically-isolated transmit-ground connector that are configured such that the receiving antenna is not capable of being used by the transceiver unless the transmit-ground connector is connected to a ground-on-transmit connector provided by the transceiver. As a result, damage from the accidental transmission of RF signals into the receiving circuitry of the transceiver is prevented.

Abstract: The mast (11) of an antenna is pivotally carried by a post (12) by a hinge assembly (13). A pedestal (33) is carried by the post (12) and is adapted to carry a winch (40) having a line (46) with a hook (47) at the end thereof. A hook mount (50) is carried by the mast (11) and is adapted to receive the hook (47) of the winch (40). A locking bracket (56) is carried by the mast (11) and is connected to the pedestal (33) when the mast (11) is positioned adjacent to the post (12). An insulator bar (29) is positioned between the mast (11) and the hinge assembly (13) and the locking bracket (56).

Abstract: An antenna includes a feedpoint support plate (10) which is provided with terminal connectors (27, 28) to attach feed wires (25, 26) to dipole lines (31, 32). A balun (33) of one size may be connected to the plate (10) by fastening assemblies (43, 44, 45) received at apertures (29, 30) in the plate (10) and at apertures (41) of the balun (33). Baluns of other sizes may also be connected to the plate (10) by fastening assemblies (64, 65, 66) received at apertures (62, 63) in the plate (10) and at holes (60, 61) provided with the coil (57). The plate (10) can also carry a strain relief bracket (70) which includes grip members (76) which engage the feed line (24) at two spaced locations with a loop (79) formed therebetween to isolate a coupling (34) from any strain.
