Build a Simple Dipole
Use the STEMulation for a starting length, build it a little long, then measure and trim.
Projects & Experiments
Take it off the screen.
Build something, measure something, compare the result with the lesson, and find out what the real world does to the simple formula.
Measure with an Antenna Analyzer
Learn what the analyzer is showing before chasing the lowest number on the screen.
Receive-Only Experiments
Use a radio or web SDR to explore signals without needing to transmit.
Project pattern
Predict → Build → Measure → Compare
The goal is to understand why a real measurement may differ from the simple model.
