What is the function of a loading coil in an electrically short antenna?
Pick an answer to check it.
Answer: D. To resonate the antenna by cancelling the capacitive reactance
A short antenna looks capacitive. A loading coil adds inductive reactance that cancels it, making the antenna resonant.
Tip: Coil cancels capacitive reactance.
