Receiver Circuit Question -- What role does this antenna capacitor play?

AI Thread Summary
The antenna coupling capacitor in a receiver circuit is essential for maintaining proper operation and selectivity. It provides lossless isolation between the antenna and the tuned circuit, allowing for adjustable coupling that enhances sensitivity and prevents oscillation issues. The capacitor transforms the antenna's resistance, enabling optimal energy transfer while minimizing reflections. Without it, the receiver's performance can degrade significantly, making it unusable. Overall, the coupling capacitor is a critical component for ensuring effective signal reception and circuit functionality.

You need to be vaccinated against your BPF mind virus.

Well doctor, what is wrong with it? Wasn't my concern in two last paragraphs of #99 clear enough? I think that such question arise quite naturally at that point. And I would like to appreciate to understand "what is wrong" in my reasonings concretely. We should talk here about science, not mysticism.
