Lindenblad Antenna Construction for Satellite Reception
Find schematics and guides for building Lindenblad antennas, ideal for receiving signals from LEO satellites and other applications.
The Lindenblad antenna is a popular choice for hams interested in satellite operation, especially for receiving signals from low-earth orbit (LEO) satellites. Its design provides a nearly omnidirectional radiation pattern with circular polarization, which helps mitigate signal fading and polarization shifts often encountered with satellite QSOs. Operators frequently build these antennas for VHF and UHF bands, where most amateur radio and weather satellites transmit.
Many hams enjoy building Lindenblad antennas as homebrew projects, often using common materials like twin-lead or fencing wire. Resources in this category provide detailed construction guides for various bands, including 2 meters and 70 cm, and for specific applications like NOAA weather satellite reception. You can find plans for both simple dipole-based designs and more complex parasitic Lindenblad antennas, with some projects even incorporating 3D-printed parts for easier assembly.

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 -
