Abstract: A portable satellite dish antenna system for carrying by a user to a remote location. The system includes a base mount having a peripheral edge with a handle formed thereon. A length of cable is stowed in a carrier in the mount. A pivoting mechanism is connected to the dish and to the mount to move the dish between a carrying position and a deployed position. In the carrying position, the dish is held parallel to the mount and the handle. The mount has a formed opening opposite the handle. This enables the feed horn, when in the carrying position, to locate in the formed opening, thereby reducing the space between the dish and the mount during carrying. The user of the system grips the handle and twists the mount in a direction to align the dish with a desired direction based on a compass reading located on the mount. The mount has a formed linear track located between the handle and the formed opening having a plurality of elevation marks.

Abstract: A compact, mechanically-steered antenna especially applicable for mobile terminals for receiving signals broadcast by satellites, is adjustable in azimuth and elevation. The antenna's active element can be rotated in azimuth through 360 degrees. Rotary couplings in the signal path are avoided by means of a flexible coupling.

The active element is mounted upon a first support member and rotatable relative to it about the boresight of the antenna. A second support member is mounted upon a base member and rotatable relative to it in azimuth. The first second support is mounted upon the second support by means of a hinge coupling which permits pivoting of one support member relative to the other to adjust the elevation angle.

Abstract: An improved Global Positioning em antenna adaptor allows fixed antenna height measurements by removably attaching an adaptor plate to a conventional surveyor's tripod. Antenna height is controlled by an antenna boom which is a fixed length rod. The antenna is attached to one end of the boom. The opposite end of the boom tapers to a point sized to fit into a depression at the center of survey markers. The boom passes through the hollow center of a universal ball joint which is mounted at the center of the adaptor plate so that the point of the rod can be fixed in the marker's central depression. The mountains of the ball joint allow the joint to be moved horizontally in any direction relative to the tripod. When the ball joint is moved horizontally, the angle between the boom and the vertical changes because the boom's position is fixed at its lower end. A spirit level attached to the rod allows an operator to determine when the boom is plumb.
