Double Biquad Wifi Dish
Repurpose the Junky Old Dish Fig. 1 Large (76cm) dish with a biquad antenna 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. Hannah arendt le origini del totalitarismo ebook login. 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. 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. 2 Dish 500 and LNBF Fig. 3 Unprotected biquad antenna will corrode outdoors Fig.
4 This antenna was housed inside an enclosure and it did not corrode You can mount the “naked” biquad [Fig. 3] or place it in an enclosure first which will protect it from weather [Fig. The actual rigging method is something you’ll have to decide based on the materials you have. I tried mounting the antenna directly to the arm of the dish [Fig.
In this instructable we demonstrate how to build a simple but power double bi-quad WiFi antenna. Given a good line of sight (LOS) with few trees or buildings in the way, a directional antenna like this can broadcast and receive a wireless signal km's. A waveguide Can-tenna or biquad antenna can be used to feed the dish.
This method works well but all exposed copper pieces will oxidize quickly. In addition, an exposed antenna can be easily damaged should the dish lose footing. A better way is to house the antenna in an enclosure and mount it using a support made of PVC electrical conduit pieces [Fig. This method was useful on a Dish Net parabolic dish to elevate the position of the antenna. Dish Net dishes have a chunky LNBF that sits up high.
Anything you can do to lift the position of your antenna and make it close to where LNBF sits will help. 5 Mounting biquad antenna on Dish 500 Make a provision to rotate the antenna 90 degrees [Fig 6]. The ability to rotate 90 degrees will allow you to match the polarization of the distant antenna you’re connecting to. 6 Biquad antenna polarization Fig. 7 Dish 500 fitted with WiFi antenna looking down All satellite dishes are designed to point up to the sky. Even when the dish is seemingly 90 degrees to the ground it is still looking up. To properly aim the beam you will need to point the dish down [Fig.
