Step By Step: Build A Tin Can WiFi Booster. Save Money And Boost Your Signal.

Some houses are not very WiFi friendly! In certain rooms you may notice that your signal strength drops significantly, or is not present at all. In these cases, either you could go to your local electronics store and spend a king’s ransom on a WiFi booster, or try to make one.

You can build your own out of a tin can! This article will show you how to re-use a tin can to help boost your wireless router’s signal and get reception in places you couldn’t before!

    Still wondering about the two coins, a piece of paper, and USB connector using body electricity to charge a phone.

    Believe it…they do work but the only drawback is the narrow beam width. I was a microwave & troposcatter tech in the ARMY. WE used some odd looking Antennaes to do specific jobs. We had everything from 120 foot movie screen like down to the blow up parabolic antennae. I worked on a system with 8 foot dishes and we also had 32 foot dishes on 2 of our other systems. To help aid in getting good signals we used frequency and path diversity to help out. You transmitted on two frees separated by a few mega hertz and spaced the dishes a distance apart. Problems with frequency shift affected usually one freq more than the other. The space ingredients took care of any path shifts between the two systems. I don’t remember if the also changed the polarization between the 2 but that would also help in cases where the polarization shifted after bouncing off of a mountain and echoing back into the area.

    Usually 2 receivers were attached to each dish. And a single 1kw watt klystron amp feeding each dish. This was for the shorter paths. For long lines they used the 60 to 120 foot screens fed with 10 kw amps. Same idea except they were aimed at the Troposphere level and picked up reflections at the distant location. They were used from Vietnam to Hawaii and into Thailand and from North to south Nam.
    Down at the uhf and vhf there were multiple types of directional Antennaes used. It mainly mattered who and where you had to communicate with. My shot to Ving Chau had to shoot between mountains. During the monsoon season the rains in the mountains played havoc with our receive levels. What the engineers decided to try was a bank shot off the face of one of the taller mountains. We moved the van and dishes about 200 feet north I believe then sighted the dishes for the mountain. After the final alignment the system quieted down. Except on the worse rainfall between us. It didn’t last long compared to what it use to be.
    So 1kw with a dish with say 20 dbi gain finally did the trick. They ended up moving one of the other systems with the 32 ft dishes for the same reasons.

      Thank you for this wonderful education.
