Abstract: The present disclosure is directed to a sub-reflector assembly for a point-to-point antenna. The sub-reflector assembly includes a main body configured to hold an antenna, a sub-reflector supported by a plurality of support members extending axially outwardly from the main body, and an adjustment mechanism coupled to the sub-reflector and at least two of the support members, the adjustment mechanism configured to adjust the position of the sub-reflector relative to the main body to steer an antenna beam from the antenna. Related antenna assemblies are also described herein.

Abstract: A cutting tool includes a cutting head integrated into a handle. The cutting tool can be used to make a window cut in a cable jacket by sliding the cutting tool along the cable jacket. The cutting tool includes guide surfaces to control the cutting depth into the jacket and to maintain the blade edge at a predetermined depth until the end of the stroke. The cutting tool also may direct a scrap portion of the jacket out of the cutting tool away from the cable. The blade of the cutting head is angled relative to a cable guide channel and is easily replaceable.

Abstract: A flat drop cable has notches or other structures for enhancing the stripability of the jacket from a core of the flat drop cable. The notches can have an angled configuration with surfaces that converge as the notches extend into the jacket. Inner edges, or rounded valleys, at the bottoms of the notches can be positioned along a tear path that intersects the core of the flat drop cable at an angle relative to a major axis of the flat drop cable. For example, the notches can be offset from a minor axis of the flat drop cable a sufficient distance such that the notches are positioned outside a central boundary region that extends tangent to sides of the core and parallel to a minor axis of the flat drop cable. The shoulders of the notches, where the notches transition to an outer jacket wall, may also include a radius of curvature.

Abstract: A cable includes an inner core. In one embodiment, the inner core includes at least one optical fiber, plural flaccid strength members, such as aramid yarns, and at least one rigid strength member, such as one or more GRP rods. A jacket surrounds the inner core. The jacket has an undulating thickness which results in plural projections formed on an outer surface of the jacket, extending along the length of the cable. In a first embodiment, the at least one optical fiber is centrally located within the inner core and surrounded by a buffer tube, which is surrounded by plural GRP rods. In other embodiments, the at least one optical fiber is centrally located within the inner core and located within a channel formed in a single GRP rod or located within a buffer tube, which is placed in the channel formed in the single GRP rod.

Abstract: In certain embodiments, a linear adjustment mechanism includes an adjustment plate, an adjustment nut, and a holding plate. The adjustment plate has an exterior-threaded section that engages with the adjustment nut, a mounting-bolt opening, and a clamping-bolt slot. The holding plate has a horizontal section having a clamping-bolt opening, a vertical section connected to the horizontal section, and an adjustment-nut opening. With (i) the adjustment nut engaged with the adjustment-nut opening and the exterior-threaded section of the adjustment plate and (ii) the clamping bolt inserted within (a) the clamping-bolt slot of the adjustment plate and (b) the clamping-bolt opening of the holding plate, (1) rotation of the adjustment nut on the exterior-threaded section of the adjustment adjusts the linear position of the adjustment plate relative to the holding plate and (2) rotation of the clamping bolt secures the linear position of the adjustment plate relative to the holding plate.

Abstract: A method of adjusting the pointing angle of an antenna includes mounting an antenna on a mounting structure with an antenna mount that includes a clamp member fixed to the mounting structure, a first adjustment bracket pivotally attached to the clamp member, and a second adjustment bracket pivotally attached to the first adjustment bracket, the antenna being mounted to the second adjustment bracket. The first and/or second adjustment brackets includes an access hole for receiving a toothed hand tool. One of the clamp member, the first adjustment bracket and the second adjustment bracket includes a toothed section. A toothed hand tool is inserted through the access hole to engage the toothed section; and rotated to pivot the first adjustment bracket relative to the clamp member or the second adjustment bracket relative to the first adjustment bracket. The pivoted bracket is secured to set the azimuth or elevation angle.

Abstract: An electric conductor incorporates at least one optical fibre and has a central axial element with at least one layer of elements helically stranded about it. At least one of the elements, preferably the central axial one, includes at least one optical fibre which is enclosed in a longitudinally extending welded metal tube (typically stainless steel). A second metal tube of greater thickness and higher conductivity than the welded metal tube and having an unwelded longitudinal seam surrounds the welded tube. The second tube is typically of aluminium and served to increase the diameter of the element so that a greater range of useful conductor sizes can be formed by using it in conjunction with appropriately chosen wire diameters.

Abstract: A folding seating unit for a vehicle provides a forward or rearward facing seat with a backrest which is capable of being folded flat and sideways against the side of the vehicle at a low level beneath the window level of the vehicle. The seating unit can be stowed within side trim panels without obscuring windows, or the load carrying area of the vehicle floor, and is particularly suited to multipurpose vehicles or vans. The seating unit includes: an outboard leg coupled to the vehicle side, and an inboard leg engaging with the vehicle floor, a retraction mechanism providing automatic folding of the inboard leg when the seating unit is folded to its stowed position; an extending backrest squab which extends the effective height of the backrest when the seating is in a deployed condition, but retracts when the seating is in the stowage position.
