Plain-language answer: Voltage distribution shows RF potential difference along an antenna and feed system relative to its local reference.
Why it matters in the antenna
High-voltage regions often occur near open ends, traps, capacitors, and loading components, creating arcing, insulation, and public-contact concerns.
What to verify
Preserve clearances, use rated insulation and components, tune at low power, and keep people away during transmission.
The common mistake
Assuming low transmitter voltage means every point on the antenna is touch-safe.
Operating boundary
Use the exact documented component, geometry, frequency, power, duty cycle, clearances, and feed/return system. Begin tests at low power and stop for heating, arcing, damaged insulation, or unstable supports.
