How to improve your WiFi router antenna

Transform your regular WiFi router's antenna into an improved one that will have a longer range, and all this can be done in 15 minutes at no cost.
Very often, inexpensive WiFi routers use a narrow-band whip antenna. Essentially it's just a piece of wire. Expensive routers already have a longer antenna with matching turns. Naturally, such an antenna catches many times better. I use a cheap router model at home, for which I will make a good antenna, similar to the expensive models.
So, let's get started...
Remove the top plastic from the antenna.

A small screwdriver works great for this.
It is necessary to repeat the shape of the improved antenna, as shown in the photo

You will need: small insulated or bare copper wire, wood screw, measuring tape and soldering iron

Measure 7 cm of wire and make a bend in this place

Using the screw as a template, wrap a full seven turns of wire around it, starting from the marked location. To remove the screw, turn it counterclockwise.
Cut the wire 2 cm below the resulting spring.

After this you need to strip 3mm of insulation or strip 3mm of bare wire (depending on which one you are using).

Cut the standard antenna wire, leaving approximately 6mm
After this, remove 3 mm of insulation.
Solder the new antenna to the remaining wire.

To do this, you need to overlap the bare parts of the wires.

Take a large cocktail straw and place it on the antenna.
For example, these are used at McDonald's.
The straw should also be ideal for the base of the WiFi antenna.
You won't even need to glue them together. It looks like it was intended that way.
To prevent the straw from standing out, you can color it with a permanent marker.

All is ready.
Looks pretty good. At the output you get an omnidirectional antenna with a gain of 5 dB. It works great both on the adapter and on the router.

    Antennas are tuned by instruments. And at these frequencies, the thickness and length of the conductor in fractions of a millimeter, and in which housing the antenna is located, is of great importance.

    But what if the router does not have an external antenna?

    Doesn't work. When connected it gives minus 10-15 dB.

    Don't forget that you are increasing the power of the microwave radiation. Which is detrimental to health.

    Igor is absolutely right. You will only worsen the performance of the standard antenna.
