Abstract: A telecommunications pole is wrapped along substantially its entire length with fabric, polymeric film, or weather-resistant paper, which displays camouflage, such as camouflage simulating bark or camouflage simulating foliage, and which is attached detachably to the pole. The fabric, film, or paper is wrapped around the pole in separate pieces, one above another along the pole, or a single piece. Each piece is attached detachably to itself via a releasable fastener or releasable fasteners, preferably a hook-and-loop fastener and alternatively a series of snap fasteners, or a zipper. Each piece may be suspended from the pole before being attached detachably to itself.

Abstract: A tubular member, which is made of steel and which is useful as an upright, structural member in a pole, pylon, or tower, is filled at least partially with a foamed material protecting said member against internal corrosion and against pest infiltration. The tubular member comprises plural sections, which have end flanges and which are bolted together at the flanges, and comprises gaskets to prevent the foamed material from being extruded between the flanges.

Abstract: A barrier, which is intended to intercept a crashing airplane before it reaches a target, comprises an array of spaced towers. Each tower is several hundred feet tall. Each tower comprises a trusswork including three steel tubes, which are filled with a cementitious material, such as grout, in a triangular array wherein one tube is closer to the target. Guys interconnect the towers to one another and to ground anchors. Each tube comprises plural sections having end flanges, at which those sections are bolted to one another, and gaskets to prevent the cementitious material, as it is being pumped, from being extruded between the flanges before it has cured.

Abstract: An antenna-mounting structure is disclosed for mounting an antenna to a vertical wall or on a sloped, peaked, or horizontal roof. A primary strut, which is tubular, has a straight, upper portion, a straight, intermediate portion, and a straight, lower portion. The upper portion has an outer, cylindrical surface, circular in cross-section, and is bent at an upper juncture between the upper and intermediate portions and at a lower juncture between the intermediate and lower portions. The upper and intermediate portions generally define an obtuse angle and the intermediate and lower portions generally define an acute angle.
