Plain-language answer: Distributed capacitance is the many small capacitances between turns, conductors, layers, hardware, and surroundings in a real RF component.
Why it changes the path
It combines with inductance to create self-resonance and changes impedance, balance, bandwidth, and voltage distribution.
What to observe
Keep winding and lead geometry consistent, measure across frequency, and include the installed enclosure and nearby conductors.
The common mistake
Treating a coil or transformer as pure inductance.
Planning boundary
Propagation models and field regions depend on frequency, geometry, terrain, atmosphere, polarization, antenna pattern, and measurement distance. Use them to plan and compare—not to guarantee a contact or installed range.
