Increase the operating range of your wifi signal by up to 2x with this hack! You can put this simple yagi antenna on a regular wifi antenna to make it more directional, and boost the signal by up to 6dB.
No 3D printer required to make one of these! This 'thing' is a derivation of a design shared by Brian Beezley, so if you are interested to know more about how it works, or want to build one without a 3D printer, be sure to check out his post here: http://ham-radio.com/k6sti/wifiyagi.htm
The original work was also featured on Hackaday: https://hackaday.com/2017/01/24/a-simple-yagi-antenna-for-your-wi-fi-router/
This print has multiple pieces:
- the body
- the nut
- and, the finger grips
After printing, the finger grips are to be glued into the body with super glue, making sure that the trapazoidal end is upward, and the taper is inward.
While the glue is drying, you can cut the wire for the two parasitic elements. Cut a 2" and a 2-1/4" piece of 14ga copper. Straighten them, mark the mid-point, and insert the short piece closest to the antenna axis and the longer piece into the furthest location. Align the midpoint to a common reference for each element.
That's pretty much all! Now, pick a cinch nut that fits your antenna best, screw it on to the body, and mount to your wifi antenna for increased range! Be sure to experiment with the direction it is pointing and the height along the antenna axis.
