¡Cuidado! ¿Sirven para algo las antenas baratas de Aliexpress? La verdad aquí…
In this video, I analyze several dual-band (VHF and UHF) walkie-talkie antennas, including original models from Baofeng, Quansheng, and other budget brands from AliExpress. Using a calibrated NanoVNA, I test their resonance at different frequencies, their SWR, and whether it's really worth replacing the factory antenna with a low-cost one. If you're thinking about buying a cheap antenna for your walkie-talkie, here you'll see if they actually work or are just for kids to play with. I also show you what to do with antennas that don't resonate at the indicated frequency. 🔧 Equipment used: Calibrated NanoVNA Baofeng, Quansheng, and generic antennas from AliExpress Springs and enamelled copper wire 👍 If you found this analysis helpful, please like and subscribe! #antennas #baofeng #vhf #uhf #aliexpress #nanovna #amateurradio
