https://www.youtube.com/watch?v=GWq6L94ImX8 https://www.youtube.com/watch?v=GWq6L94ImX8 This is English dubbed Russian video of extending WiFi with proper antenna. There are series of these videos by Kreosan. They improve antennas over time. I believe they achieved range of a few kilometers. Wi-Fi frequency and chip are standard, antenna is the only component improved.

With a directional/high-gain antenna you're increasing the ERP (effective radiated power) which may well put you above the legal limits in your jurisdiction. So be careful. Aside from that, a much simpler antenna is this one, which can be built from a metal can + connector + wire stub. Directionality is likely a bit worse but I've used it successfully over a distance a bit lower than a kilometer. https://web.archive.org/web/20060516103023/http://www.saunalahti.fi/elepal/antenna2.html https://web.archive.org/web/20060516103023/http://www.saunal...

  Yes! Everyone should own a cantenna or 2, or 3... I built a 2ft diameter version during COVID for radio astronomy.

    Can you tell more or link to a description? What where you able to observe?

      I observed the "H-Line", https://en.m.wikipedia.org/wiki/Hydrogen_line https://en.m.wikipedia.org/wiki/Hydrogen_line Made a GIF of the transit of the milky way using this software on a raspberry pi with some SDR/RF equipment. https://github.com/byggemandboesen/H-line-software https://github.com/byggemandboesen/H-line-software Unfortunately I only have some images on my phone right now, a git page is on my todo.

  Yes, be very careful to stay within lawful ERP. Some devices are illegal to use with external antennas. Of those that can connect an external antenna, the specs of acceptable antennas are provided with the equipment. If you are in the USA, and you have the appropriate Amateur License (Tech class or higher), and you choose channels that are in the Ham Bands, Then it's perfectly fine to use these as ham radio links. https://www.arednmesh.org/ https://www.arednmesh.org/

  Yeah, be SUPER careful, the Wifi snooper vans are always out… looking for violations. You could be sent to Siberia for this. /s

Thanks for posting. This is what I was going to suggest as well. Its a great project for learning RF.

Interesting video. I wonder what would happen to most of these russian gadget hackers with current war drafting.

  Actually, this guy lives in Luhansk, active war zone in eastern Ukraine. https://www.nytimes.com/2015/07/18/world/europe/in-bleak-ukraine-city-a-duos-odd-experiments-win-a-niche-online.html https://www.nytimes.com/2015/07/18/world/europe/in-bleak-ukr... Perhaps most unusual about the pair is that in a war that has deeply divided Ukraine, where no one is indifferent, the two say they are neutral. Rather, the conflict is part of a landscape that emerges in rare moments, like the distant reports of artillery fire at the end of one video. That neutrality is not a calculated stance to avoid offending viewers. It is one of faith. “The lord Jesus Christ does not take sides, and we must strive to act in his image,” Mr. Kryukov said. “We study the Bible, and our members, we call them brothers and sisters, live in Russia and Ukraine. If we picked a side, we would become an enemy to someone. And we don’t want to be enemies with our brothers and sisters.”

      Yeah no way someone with this kind of skill doesn't get drafted.

    If you can't pick a side between mass murderers and rapists building torture camps where dead kids once sat to learn in a language and culture the invaders are trying to erase that is a substantial moral error. Even jesus said love the sinner not ignore his sin. The fact that they have themselves fled the war zone if anything makes it worse. They are hypocrites as well as cowards.
