Thank you so much for your kind reply. You're extending your WiFi reception (not broadcast). Now the re-purposing of the satellite dish makes perfect sense. With increasing numbers of public WiFi hot spots, from coffee shops and colleges to municipal parks and libraries, a person could use your Instructable to get online in areas with a weak but still viable public signal. In our area, that could potentially save students and other people with limited resources as much as $50 a month for broadband internet access, all without breaking the law. Brilliant!
The design is directional and works best pointing at something although side signals are picked up as well. As for a use, I have it pointed at a local library that offers free wifi. Since I'm in a place where the power goes out a few times in the winter (but not at the library, different power grid), I can still access the internet with my laptop in emergencies
Got it. Thanks great idea1 - Boot2000
Please forgive my ignorance, but is your design directional (i.e., does it work best in the direction the dish is pointing)? If so, what is this device's primary purpose? Twenty years ago we were all eager to share our WiFi with our neighbors and were happy to let strangers use our bandwidth; today we're afraid some pervert is going to park in front of our houses and download nasty stuff using our IP address. How things have changed! Anyway, I just don't get what a sat-dish-based WiFi extender will do for you. I'm sure the answer to this must be obvious to most readers, but I'm curious and (in this case) completely clueless. Don't be too hard on me! And a sincere "THANK YOU" for all the time and effort you put into developing this Instructable. I'm all for re-using and re-purposing whenever we can, and surplus satellite dishes are a blight. Keep up the good work! - Taz-Hood
waveguide for WiFi is slightly different dimensions than the end of the Ku-band head! For the normal "transmission" wave to the receiver waveguide diameter for 2.4GHz should not be less than 87mm internal diameter. Or a rectangle with sides of 87mm to 43mm (abowe 86.36mm to 43.13mm).If you want to understand about the size of "input feed" for a dish - take the crown C-band (3.4-4.2GGts) and Increase it twice - ТвинкБ
For step 3 why don't you just use a pipe cap? It will be stronger, cheaper, and it will seal itself.Same with step 4. A 3" to 1-1/2" reducer fitting is cheaper and stronger than the handmade wood adapter. And, again, sealing will not be a concern. In fact, it's not clear why you even need a different size pipe. Why not make the whole thing out of a single straight 1-1/2" pipe or a single 3" pipe?Also, you absolutely do not want to put desiccant inside this container. It will have the opposite effect you intend. Rather than keep the container dry it will actually draw moisture into the container. If your seals leak in the rain then a desiccant isn't going to fix that. Unless you intend to check and replace the desiccant weekly then a desiccant is just going to make failure due to moisture occur sooner than without the desiccant. - noahspurrier
One of the reasons I didn't use a pipe cap on the three inch pipe was because I wanted to be able to take the cover off again to access the inside. As for making it one size pipe the wifi unit is too large for the 1 1/2" pipe and the three inch pipe is too large for the original mount. You could change the design if you also change the mount. For not using a reducer I like to build with what I have on hand and I didn't have one. Of course a reducer could be used and it would be easier. This whole thing can be easily modified and made better and I'm looking forward to seeing how others have improved it.
