You can build a highly effective rectangular horn antenna using stiff cardboard sheets lined smoothly with aluminum foil, or sheets of lightweight galvanized sheet metal. Online calculators (like the Kraus Horn Antenna Calculator ) provide exact dimensions based on your target frequency of 1420 MHz.

The universe is filled with neutral hydrogen gas. When the electron in a hydrogen atom flips its spin state, it emits a specific radio photon at a wavelength of 21 centimetres, or a frequency of 1420.4 MHz. By tuning your telescope to this exact frequency, you can trace the spiral arms of our own galaxy. 1420.4 MHz.
For absolute beginners, passive radio astronomy is the safest starting point. Radar requires amateur radio licenses (e.g., FCC Ham License) to transmit legally. Grab a basic RTL-SDR kit with bundled general-purpose
