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.

biquad antenna
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.
