ADS-B: Build a simple ground plane Antenna
Materials: solid copper wire (12, 14, 18 – whatever you have available!) SO-239 LINK Soldering Iron and solder Tape, Ruler, calipers or anything to measure a wire to a lenght of 75mm then finally the “snip length” of approximate resonance 67mm (technically the resonance is at 65.5mm… but from my experiments, 67mm does the trick!) Let’s get started: Steps: Cut and strip 9 pieces of wire to about 75mm each Take 8 of them and give them a “L” hook…
