Reinforce WLAN signal with satellite dish from CD and satellite dish.

Finally everything at a glance: The 82 best “brilliant tricks”, summarized in a high-quality book. Here you can order it.

“I do not have a net!”, One unfortunately hears too often when surfing the internet on the go. And even if you have network, the connection is sometimes so bad that it takes half an eternity for the websites to build on the phone.

If you are already confronted with this problem in the big city, it is only worse in the countryside. But a resourceful hobbyist from the United States has got away with a satellite dish and a CD.

He has made a parabolic antenna with which he could amplify the incoming signal and increase the range. For that he needed:

a satellite dish
a CD
a USB Wifi adapter
a tin can
two wooden slats for the base
a cooking pot lid


He also needed different screws and tools to drill, cut and glue.

And this is how you can imitate it:

First, the CD is curved by heating in the oven. It is placed for this purpose in a small saucepan lid, the handle was unscrewed so that it can be placed upside down on the baking sheet.

The oven is not preheated, otherwise the CD would splinter and the film would peel off. The CD is “baked” for about one hour at about 150 ° C.

Immediately after taking the CD out of the oven, you must press down on its center with something heat-resistant, such as a spoon, to take on the parabolic shape.

Then the CD has to cool down.

The tin can be cut in half vertically, leaving the soil intact.

Near the top edge, at the level of incipient corrugation, a hole is cut into the wall of the can, through which later the USB plug must fit. In addition, as shown, a hole is drilled in the bottom of the can.

The slot in the middle of the bottom of the can, which can be seen in the picture, is irrelevant.

The parabolic CD is glued to the inside of the can wall with hot glue. The hole of the CD must be at the same height as the hole in the wall of the can.

The can is screwed onto the multifeed rail of the satellite dish.

The plug of the Wifi adapter is pushed through the hole of the CD, the plug of the USB cable through the hole in the socket wall, so that both can be connected to each other.

Two wooden slats are also used to build a base on which the satellite dish is mounted.

The USB cable is connected to the laptop. Now weak Wi-Fi signals can be received much stronger – with this construction alone from a distance of 400 meters, but with the right equipment but distances of up to four kilometers are possible, the hobbyist.
