Review on Tupavco TP511 WiFi Panel Antenna 2.4GHz (20DBi) Outdoor Directional (2400-2483 📶 MHz) Wireless Network Signal (Pole Mast Mount) Weatherproof High-Gain Long Range (N-Female Connector) by Austin Hampton

This is a very powerful directional antenna with a gain of 20 dBi and an opening width of 18 degrees. I'm using a couple of these along with a couple of GL.iNet GL-AR150 radios, a USB power bank and a 10 watt USB solar charger to make a Wi-Fi solar repeater/bridge. A couple of these babies really resonate in the distance, if you get my meaning. It can project a strong Wi-Fi signal up to a quarter mile ahead. They are amazing - solid construction with a sturdy, adjustable bracket. Definitely wind and waterproof. True professional quality. Remember that they are set to 2.4GHz, not 5GHz.
