Abstract: An apparatus for reducing the wind resistance of an antenna is provided. The apparatus includes a radome, an upper end cap and a lower end cap disposed on the upper and lower ends of the radome. The radome includes a windward surface, and at least one of the upper end cap or the lower end cap includes a bottom edge and a front contour surface. The front contour surface is formed by extending and bending from a portion of the bottom edge close to the windward surface in a longitudinal direction toward the center of the upper end cap or the lower end cap.

Abstract: An end cover includes an end cover plane perpendicular to a longitudinal axis of a radome and passes through a connection part of the end cover and the radome. Outlines of a cross section of the end cover includes a first spline curve between a first end point and a first intermediate point having at least one first curvature, and a second spline curve between a second intermediate point and a third intermediate point having at least one second curvature. The first intermediate point and the second intermediate point are not in the end cover plane. A distance between the first intermediate point and the end cover plane and a distance between the second intermediate point and the end cover plane are equal and not less than a distance between any point on the cross section of the end cover and the end cover plane.

Abstract: A facsimile transmission relay apparatus, referred to as an Intelligent Facsimile Relay (IFR) for improving call success rates in long delay environment such as terrestrial cellular, fixed wireless, and geostationary mobile satellite systems and the like. A first bi-directional telecommunications interface is provided for receiving facsimile signals from a transmitting facsimile device via a first network such as a Public Switch Telephone Network (PSTN). A buffer memory is used by the IFR for storing the facsimile signal, and a second bi-directional telecommunications interface retransmits the facsimile signal via the second network.

A buffer memory is used by the IFR for storing the facsimile signal, and a second bi-directional telecommunications interface retransmits the facsimile signal via the second network, e.g., a wireless network, to a receiving facsimile device to avoid signal collisions between the devices.
