An antenna protector includes a top wall, a first side wall, a second side wall, and an end wall. The top wall includes a center reinforcement that includes a plurality of lateral ribs and longitudinal ribs protruding from the top wall and arranged in a grid formation. Each of the first side wall, the second side wall, and the end wall include a perimeter reinforcement that includes a plurality of vertical ribs protruding from the wall. In an exemplary embodiment the antenna protector may include an open end portion, a closed end portion, and a center section, wherein the center section is narrower in width than each of the open end portion and the closed end portion.

A method is disclosed for alternately covering and exposing feed cables to a wireless telecommunications antenna from a pole-mounted RF source. The method deploys a resiliently stretchable tubular shroud, which has a proximal opening attached near the top of the pole and a distal opening alternately attachable to a section of the antenna proximate to the cable connections or to a section of the pole below the proximal shroud opening. In the former configuration, the shroud covers and protects the feed cables, while in the latter configuration, the retracted shroud exposes the cables for repair, maintenance, replacement and/or inspection operations.

Techniques for tuning a crossed-field antenna are provided. An example of an antenna system includes a D-plate with a D-plate feed conductor, such that the D-plate is a horizontal conductor raised above and insulated from a ground plane, an E-cylinder with an E-cylinder feed conductor, such that the E-cylinder is a vertical hollow conductive cylinder of smaller diameter than the D-plate, which is mounted concentrically above and insulated from the D-plate, a transmitter tuning circuit configured to receive a signal from a transmitter, an E-cylinder tuning circuit operably coupled to the transmitter tuning circuit and the E-cylinder feed conductor, and a D-plate tuning circuit operably coupled to the transmitter tuning circuit and the D-plate feed conductor.

To reduce a dielectric loss while determining a direction of an antenna formed on a flexible board.

An antenna device includes: a flexible board including an antenna and a signal line coupled to the antenna, the antenna and the signal line being formed on a front surface side of the flexible board; and a support that puts the flexible board in a predetermined shape, the support having a shape that does not cover at least a part of a second region of a back surface of the flexible board, the second region corresponding to a first region in which the antenna and the signal line are formed.

Systems and methods for receiving GNSS and corrections signals by a GNSS rover. The GNSS rover may include a radome enclosing a GNSS antenna and a GNSS front end. The GNSS rover may also include a corrections antenna attached to a connection housing and configured to receive corrections signals from a base station. The connection housing may be configured to removably attach to the radome. The GNSS rover may further include a corrections front end enclosed within the radome and electrically coupled to the corrections antenna via capacitive coupling when the connection housing is removably attached to the radome. The GNSS rover may further include a first capacitor plate enclosed within the radome and positioned substantially parallel to an outer wall of the radome and a second capacitor plate enclosed within the connection housing and positioned substantially parallel to an outer wall of the connection housing.
