Have worked with angled Wi-Fi antennas before.
Hi there! I heard about directional Wi-Fi antennas too. I followed this tutorial to build a double biquad setup. After connecting it to a USB Wi-Fi dongle, I managed to get a connection over roughly 80 meters, but I’m not seeing much more. It’s possible my antenna isn’t ideal, though 80m seems quite short. Appreciate your advice!
Both the access point and client devices use WiFi antennas. You'll notice a small improvement by upgrading only the access point's antenna, as it increases both transmit power and sensitivity. For long-range directional WiFi, both sides require directional antennas. It wasn't specified if you're inside or outside, so directional antennas provide minimal advantage indoors.
The access point was inside, with my antenna outside the windows—essentially an outdoor setup. There seem to be three walls separating me from it. I noticed others often use high-gain antennas for connecting to distant free Wi-Fi hotspots, which made me think it might offer better coverage.
On 2.4Ghz with a clear line of sight you could achieve a connection, though it varied based on nearby interference. A friend once linked to a school network several miles away using a Yagi antenna; however, back then there was little WiFi available and the area was mostly forested with his tower situated high above the trees.
