Why should antenna loading coils have a high ratio of reactance to resistance?
Pick an answer to check it.
Answer: C. To maximize efficiency
A high ratio of reactance to resistance means a high-Q coil with little loss. Less loss in the coil means better antenna efficiency.
Tip: Low-loss coil = high efficiency.
