What do we need
From materials for nozzles:
- The foam backing is food packaging. You can use any other material or sheet of cardboard.
- Thick copper wire. A small segment.
Tool:
- Scissors.
- Ballpoint pen or pencil.
- Vernier caliper or regular ruler.
- Nippers.
Antenna nozzle drawing
All dimensions are in millimeters. The idea is this: a long section of a foam substrate is inserted onto the antenna, into which copper segments are inserted. This creates the directivity of the antenna and the concentration of the signal in one direction.
Above are the distances between the copper segments. And below is the length of each copper section.
I took here a pallet in which dates or greens are often sold.
A piece of thick copper wire 0.8-0.9 mm in diameter. You can try with a thicker one.
We mark the lining with a caliper and put the points with the handle where the antenna from the router will be inserted.
Draw the cut lines.
Cut the guide with ordinary scissors.
We look at the drawing and determine where and how long the segment will be inserted.
We cut the wire with the appropriate length using wire cutters.
Insert the pieces of wire into the guide. If desired, they can be fixed with hot glue so that they do not fly out.
Our nozzle - amplifier is ready for testing.
Signal Level Check
We turn on the laptop, start the program, scanning the level of signal reception. Let's wait a bit to notice the level of initial intake. Then we put the nozzle on the Wi-Fi antenna, direct it to the router and then we see an increase in power and signal level.
To check, remove the nozzle from the antenna and immediately see the signal drop to the initial level.
Again we dress and again see an increase. Everything works great.
I put a nozzle on the Wi-Fi adapter module connected to the laptop. If you want to significantly increase the reception distance, then you need to put such a nozzle on the antenna of your distributing router. Two Wi-Fi antennas pointing at each other will work just fine.
Here is such a simple and effective way to make life easier in a few minutes. Now in my garden gazebo there are no problems with the Internet, and most importantly, I didn’t have to buy anything. And we all know how much expensive antennas or routers for remote points and objects cost now. Until we meet again.
