HOW TO IMPROVE WIFI ROUTER ANTENNA

Send

Turn the antenna of a regular WiFi router into an improved one, which will have a longer range, and all this can be done in 15 minutes without any cost.
Very often, inexpensive WiFi routers use a narrow-band whip antenna. In fact, this is just a piece of wire. In expensive routers, there is already a longer antenna with matching turns. Naturally, such an antenna catches at times better. At home, I use a cheap router model, for which I will make a good antenna, similar to expensive models.
And so, let's get started ...
Remove the top of the plastic from the antenna.

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

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

Measure 7 cm of wire and bend in this place

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

After that, you need to clear 3 mm of insulation or strip 3 mm of bare wire (depending on which one you use).

Cut the wire of the standard antenna, leaving approximately 6 mm
After that, clear 3 mm of insulation.
Solder the new antenna to the rest of the wire.

To do this, lay uninsulated parts of the wires.

Take a large cocktail straw and put it on the antenna.
For example, these are used at McDonald's.
The straw should be ideally suited for the basis of a WiFi antenna.
They won’t even have to stick together. It seems like this was intended.
So that the straw does not stand out, it can be painted with a permanent marker.

Everything is ready.
It 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.
