Plain-language answer: Linear loading folds or routes additional conductor alongside a shortened radiator to increase electrical length without a concentrated coil.
Why it matters in the antenna
It can spread stored energy and loss, but close conductor spacing creates coupling and capacitance that make geometry critical.
What to verify
Maintain documented spacing, routing, symmetry, insulation, and endpoints; measure after installation.
The common mistake
Calling folded wire equivalent to the same length stretched straight.
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.
