Use a Satellite TV Dish as a WiFi Antenna

Repurpose the Junky Old Dish


A satellite dish is a powerfull signal booster when used in combination with a WiFi biquad antenna. I see lots of satellite dishes laying in trash when driving. Grab one next time you see an old dish laying on the sidewalk.

I have tried using both smaller Dish Net dishes and larger 76cm (30 inch) dishes [Fig. 1]. They both work well. The larger dish will give you some extra gain but even the small one works really well. How far you can go with this booster? I have tested it up to 250m (820 feet) with Netgear router on the other end and it worked flawlessly. The router was using the stock antenna it came with.

First disconnect the so called LNBF from the dish [Fig 2]. Then mount your biquad antenna in place of the LNBF. Ideally, it should be in the exact same position as this is the focal point of the parabolic dish.
