The article describes the construction of a Lindenblad antenna, which is well-suited for receiving signals from low-orbiting weather satellites. The key points are: The Lindenblad antenna has an omnidirectional horizontal radiation pattern and is optimized for low to medium elevation angles, making it ideal for tracking passing satellites near the horizon. It is designed to receive circular polarization, which is common for weather satellite signals. The antenna is constructed using 4 folded dipole elements arranged on a cross-shaped frame. The necessary materials include a plastic junction box, PVC tubing, and aluminum rods to form the dipole elements. The article provides detailed instructions for preparing the components, assembling the dipoles, and connecting the feed lines to create the complete antenna. The completed antenna can be mounted on a vertical support, with the dipole elements angled at 30 degrees from horizontal, to optimize reception of the passing satellites. The author notes that the design was originally published in a now-defunct magazine, Meteo Satellite Inf", in 1993

This Satellite Antenna Elevation System project involves mounting horizontally polarized Yagi antennas on a fiberglass reinforced polymer (FRP) crossboom. A Yaesu G-800DXA azimuth rotator is in place, requiring only an elevation rotation system. Elevation is controlled by a 12VDC linear actuator connected to a U-bolted arm on the crossboom, rotating within a DIY bearing arrangement. Common handyman tools suffice for assembly. The setup includes FRP crossboom, aluminum tubing, PVC couplers, nylon camshaft bushes, and a K3NG-based controller for azimuth and elevation control. Detailed guides and resources are available online.
