Two Quicky Directional Wifi Antennas

These are just a couple of wifi antennas I cooked up real quick.

If you are interested in antennas, check this one out: https://www.instructables.com/id/Foil-based-fractal-antenna/

Step 1: Parts Needed

Usb wifi adapter.
Usb extension cable.
Plastic salad bow.
2 coat hangers
Foil.
Tape.
Large parabolic screen from children's toy.

Tools.
Drill
Wire cutters

Step 2: Parabolic Antenna Prep

Take parabolic screen and use wire cutters to make a hole for the usb wfi adapter to fit.
Insert wifi adapter.
Lay unit face down for a minute.

Step 3: Finish Parabolic Screen.

Bend coat hanger to make stand for antenna
Insert stand into parabolic screen.
Done.

Step 4: Salad Bowl Antenna

Drill hole in salad bowl to fit usb wifi adapter.
Surround bowl with foil.
Tape down.
Insert wifi adapter.
Lay bowl face down fior a minute.

Step 5: Mount

Bend coat hanger to fit.

Step 6: Finish Salad Bowl Antenna

Bend coat hanger to support bowl.
Put bowl in stand.
done.

Hope you enjoy these directional wifi antennas.

Step 7: Mount It.

We decided to take a previous project and modify it for this project. Never ending uses for tripods.

Step 8: Home Made Parabola?

I had been thinking about solar cookers when I found this small picture of a parabola form. Seemed unusable at first. So using a image viewer, I enlarged the picture and then printed out. After that I then cut around the splines with scissors. I taped it up. A parabola it is.

Then comes the fun part. I printed out a second form and then glued aluminium foil to the form. Let that dry. then used the scissors to cut around the form again. Looking more interesting. Then I taped up the spines together to get an aluminium foil parabola. Now I am working on an even larger version. Awsome!

Step 9: More Precise Parabola,

I was wondering if aluminum paint would work instead of the foil?

Thanks for the instructable.

[daiatlus79]

if the paint contains actual aluminium in a considerable concentration, i cannot see why not.

Thank you for the comment. That would be a good question to ask the maker of the paint you expect to use. You could try it and if it does not work, you can still do the foil.

U should use better images...What if my wife need her salad ball?

Another instructable on the same issue...I prefer a metal parabolic dish but anyway....

You can get those bowls for a dollar. as for the images.

I have used a pie tin as a reflector, I mounted it 1/4 wavelength from the vertical antenna. (just mounted the receiver on the wall and put the tin over it.)

Thankyou for your comment. When I get a chance I probably will replace it.
