In Asia, specifically in Bangladesh, we often listen to FM radio. But the signal is not clear everywhere, that means it produces some noise.
From my childhood till today, I have observed that, if I keep the radio in a fixed position and I increase distance between me and it, the signal starts to be more and more noisy.
And sometimes, if I touch the antenna, the signal become more clearer. This is an observation from real life. But I don't know the exact reason behind it.
Would you please describe the exact reason behind it?
This question came in my mind few days before, but I was confused which site best suits for this question. However, I thought this site is the most suitable one to ask the question. If you think it is off-topic here, then don't hesitate to have a migration request to the appropriate site.
I am also sorry for my bad English.
