Make sure it will be big enough that your antenna can fit through, but not so big that it won’t fit snugly. This is where your antenna will poke through, and it serves as the focal point for all those radio waves. It’s important to put the “+” slits in the right place. This can be a pain with scissors so if you have a pocket or X-Acto knife, it will come in handy here. Remember to cut slits on the round piece where you see the “+” sign, and the six slits on the reflector. I didn’t so I just printed it onto regular paper, cut out the template, and glued that to some cardboard from a box of soda.

The antenna designsīoth of the antenna designs we use come from. This is useful if you have a room in your house where the wi-fi doesn’t quite reach, or if you own a small business with open wi-fi and you want to direct the signal away from moochers in a nearby apartment complex. This means your wi-fi will get stronger in one direction but weaker in the opposite direction. They both use parabolic reflectors to direct radio waves in one direction. In this tutorial, I will build and test two popular designs for DIY wi-fi extenders. See also: 10 ways to increase your wifi signal strength and range.

Many wi-fi extenders and repeaters are available online, but if you want to save some cash, you can make your own with a few household materials and tools that you probably have on hand.

They can be used to extend the range of your wi-fi or to boost signal strength. A wi-fi extender is a simple device that boosts the strength of the signal coming from your wireless router.
