Antennas: The Physics Rabbit Hole Hidden Inside a Piece of Wire

Recently I Fell Into The RF Rabbit Hole And Realized Antennas Are Basically Physics Speedrunning Recently I met some experts in the radio frequency space and accidentally fell into one of the deepest engineering rabbit holes I’ve hit in years. These guys were sitting there with SDRs — software-defined radios — casually dragging sliders around while entire invisible worlds appeared on screen. Airplanes. Weather satellites. Garage door openers. Random telemetry bursts. Digital chirps from devices
