1.    Build the antenna

2.    Record data without the antenna

3.    Attach the reflector to the antenna of the wireless access point.

4.    With the antenna pointed toward the test computer, measure and record the signal strength.

5.    Do numerous trials

3.    Cover piece(s) of cardboard with aluminum foil.

4.    Bend the foil-covered cardboard on coffee can

5.    Then, put a dot at 6.5cm from bottom of Styrofoam, put centre of aluminum foiled- cardboard on Styrofoam, put a 5cm dots from bottom at corners. Draw a curved line using a protractor

6.    Cut along line

7.    Repeat step 5 & 6 if more than one antenna 

8.    Glue cardboard to Styrofoam wrap with elastic bands to hold in place

9.    Drill hole in centre of Styrofoam

10.      Put the Styrofoam on the router(s) antenna(s)
