Plain-language answer: Conductor diameter changes RF resistance, inductance, capacitance, corona threshold, mechanical strength, wind area, and antenna bandwidth.
Why it matters in the antenna
A thicker conductor often broadens impedance bandwidth and lowers loss, but it also changes the electrical length and mechanical design.
What to verify
Use the specified material and diameter or re-model and remeasure the complete antenna.
The common mistake
Substituting any wire gauge while expecting unchanged tuning and ratings.
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.
