The original antenna that came with the walkie-talkies didn't work very well for listening to FM radio indoors. I bought a similar, retractable antenna online, which was very inexpensive – around 3 yuan. And surprisingly, the longer antenna actually improved reception; it gave me the feeling of having a portable sound system, just like in a square dance venue.😄
I was curious about its construction, so I disassembled it. Even though I only made 3 yuan, it's still a good profit. The construction is very simple: the inner core connects to the spring, which then connects to the handle.
