We will need:
Box of CDs.
Copper wire with a diameter of 2.5-3 mm.
Compact disk (plays the role of a reflector). You can also cut the circle of copper yourself.
Antenna cable.
We assemble the antenna itself, observing the dimensions.
Then we drill in the center of the box a hole with a diameter for the TV cable.
And saw two slots, at 90 degrees to one another (slots are needed to fix the antenna).
The main thing is to observe the distance between the reflector and the antenna, this is exactly 15 mm.
We also make four holes in the box (we will hold clamps in them for further fastening to the mast).
Now glue the reflector to the bottom of the box.
We pass the cable through the back and solder the antenna (there is no difference between where to solder the central or shield wire).
We insert the antenna into the slots and fix it with hot glue on both sides.
Now connect the WIFI adapter.
We clean the cable so that the screen braid is longer than the center wire.
From the central cable, leave about 5 mm. Of wire in isolation.
With an awl or a sewing needle in the center of the central braid (next to the wire), we puncture the central antenna wire of the adapter.
We unscrew the antenna from the adapter.
From the old marker, I cut a small piece of the tube (this will be an adapter and a clamp between the adapter and the cable).
We press the cable to the adapter (the central cable should enter a little into the adapter. So the center wires connect).
Now we wrap the screen of the adapter with the screen braid of the cable. We pull the tube from the marker over the screen braid.
That's all.
