How to increase antenna power

Hello friends! Today I will show you a way to increase the range of your Wi-Fi or 3G whip antenna. This method cannot be called standard or classic; it is a discharge design - crazy hands. Yes, to be honest, I don’t even know how exactly my device works... But it works!

What do you need for homemade?


  • The whip antenna itself, possibly with an extension cord.
  • A plastic jar for cotton swabs or another.
  • Aluminium foil.
  • Moment type glue.
  • Hot glue gun.
  • Yardstick.
  • Scissors.

Making a device to increase antenna power


First of all, we measure the diameter of the antenna, with a ruler or, as in my case, with a caliper.

We make a hole in the center of the chopstick jar for this diameter.

I picked out the hole with scissors, but it didn't work out very neatly. I hope it turns out better for you if you suddenly want to repeat my craft.
Then we take aluminum foil and cut a strip the width of the plastic jar.

And insert this segment inside.

In order for the foil to stick, it needs to be placed on glue.

We put the resulting structure on the antenna. See photo.

And so that everything doesn’t fly off, we fix it with hot glue.

Testing and result


Naturally, you shouldn’t expect cosmic results. But if you have reception sites with a very weak signal, then they will now become more accessible. My antenna level stash consists of five divisions; on average, one stick was added to each receiving point. And I think this is an excellent result.
I thought for a long time about why the signal was being amplified. And it seems to me that this happens due to the fact that the foil forms a closed circuit - a vibrator. And due to its large area, it increases the area for signal reception and transmission.
If you have thoughts on this matter, write in the comments, I will be very interested to know your opinion! Thanks to all!

    You got the simplest one horn antenna .
    I-NET has a lot of information about them. I did something similar myself
    but used the antenna built into the whistle.
    Experiment!!! This is very interesting and educational!!!

    I'll add. This antenna goes on the NETWORK as Can antenna
    However
    If you calculate the dimensions correctly megaphoneand according to the formulas,
    you can achieve a significant increase in signal level and transmission and reception speed

    If you remove the plastic shell from the original antenna, you will see a tube at the bottom that acts as a counterweight to the whip antenna. And this design seems to increase the size of the counterweight (artificial grounding) and increases the antenna gain slightly

    Excellent homemade product. Thank you. But is it possible to strengthen the signal for a modem on a laptop? This is a big problem for me. I heard that they are making something like this Horn Antenna. I think many would be interested. Alexey Vidyakin.

    Isn’t it easier to take a 0.33 or 0.5 beer can? At least beer will be beneficial.

    Does this rupantenna only amplify the signal? Is there anything that increases the speed of transmission and reception?

      Of course have! Change your provider and it will fly!
      But seriously, the speed is directly related to the signal level.
