In this video we will be having a closer look at popular phone jammer & booster videos you can find on YouTube. Such circuits either block your phones reception or increase it. So I will build 2 very popular ones, show you how they work and whether you should maybe try them out as well. Let's get started!

  • @infra-blue
    expose more of these channels that show fake and misinformative content. Thanks a lot for your work
  • @NathanielGaboni
    the rectifi- wait, wrong channel 😂 kiddin aside, love your videos!
  • @HammaBerlin
    Even the design of an antenna for this purpose is a science for its own.
  • @mrwho30
    "He who knows nothing must believe everything" But now we know, thanks! 👍
  • You are doing a great service by debunking their disservice. I started with electronics when I was 14 (over 40 years ago) and though it is not my occupation I still play around with it as a hobby. What those channels are doing is beyond dishonest because they not only present BS as facts but also discourage people who want to learn. They will try and make one of those circuits work when it doesn't they won't be able to understand why which may frustrate them to the point of giving up. So, yes, keep fighting the good fight :)
  • @steveg5166
    Definitely expose them! I hate these channels that use false information and even AI, combined with click baity titles to get views. This type of content just serves to clutter up the internet and discourage novices that might try to build the circuits and just blame themselves when it doesn't work.
  • Absolutely right!! We can’t block or boost mobile RF signal by simply these things. The mobile RF system use complex modulation technique such as OFDMA and transmission technique such as MIMO will make them more immune to external interferences. The frequency hopping spread spectrum technique will spread the signal over a wide frequency range, making it more resistant to interference and noise. Modern mobile communication systems employ sophisticated error detection and correction algorithms, such as Forward Error Correction (FEC) and Automatic Repeat request (ARQ). These techniques detect errors in the received data and correct them automatically. It also adapt to changing conditions by adjusting parameters like transmission power, modulation schemes, frequency band and data rates based on environmental conditions. From these observations it is very clear that mobile jamming / boosting is not a simple task. It requires more specialized RF IC and well-designed antenna systems along with complex signal processing algorithms.
  • plus 1 for more exposure of this fake electronics. These "creators" are giving electronics a bad reputation while at the same time making a living off the click-bait they are creating. There is too much like this on youtube...
  • @AG3n3ricHuman
    While it's obvious that circuits like these can't work at radio frequencies, it should be noted that the capacitive load of a passive scope probe will affect the circuit and most common oscilloscopes can't measure such high frequencies anyway.
  • @JakEneAS
    It's a good thing the power output is low. Interference around 125MHz is gonna piss off two regulatory authorities simultaneously. Aviation and communications!
  • Probably a good thing that all the people trying to build circuits designed to cause mayhem are distracted by these designs that don't actually work.
  • @mattikra
    I stopped believing that it could possibly work when I saw through hole components for GHz frequencies, but thanks for going all the way, very entertaining...
  • @MD4564
    These along with fake free energy videos are the worst of the worst.
  • @SuperFredAZ
    I designed television front end for several TV manufaturers years ago. You are 100% correct, keep exposing the frauds.
  • Expose more of this crap. Some people think they can tell you anything, so it is good to expose them. And on the other side, its also educative... We all learn from those "mistakes". Thank you Scott!
  • @JaenEngineering
    I'm down with debunking some more of these circuits, or even the opposite, proving some of them useful. A regular series of "Two of these designs are junk, but the third actually works. Can you guess which one" could actually be a good deal of fun.
  • @subaru5015
    Please continue, it will be great to have a reputable YouTube channel debunking all the fake videos on YouTube.
  • @azhanameen940
    I mean they are just everywhere, fake channels, it sucks seeing that majority of the content is this way We are lucky we have guys like you that give out real knowledge 🙌
  • @dustinsmith8341
    The most amazing thing in this video is that your phone can switch between the different networks.
