The dish isn't band specific, it's like a magnifying glass, only reflective: The curve of the parobela focuses all the energy that reflects off of it's surface to concentrate at a single focal point. The dish size would be awesome for signal collection though! I am not sure how sensitive the LNB would be in the router's range. You could setup the router as a wireless bridge (I think it is called) perhaps (?)Īs far as the dish network setup goes, I think the LNB is setup for a specific range of GHz frequencies and filter out others. They all attach directly to a router antenna, which may or may not be what you are looking for (especially if you do not have a convenient line of site to the library. Which were easy and fast and bumped up my signal between 10 and 20db, but that was *not* over a block. I know I left a lot of unanswered questions, the Fresnel Zone cal will give you an idea of what you need too do. You will like the Ubiquiti NS2 Loco, easy setup, cat5e, signal strenght indicator build in, etc. If the Library uses 2.4ghz 802.11g/ODFM or b. The dimentions are critical, and these are perfect.ĭistance, radio type ~Brand-Model, height of radio, down tilt if any, inside/outside, etc. Make the element 31mm long, and place the element exactly 2-1/2" from the bottom of the can.
Perfect Cantenna: Use the big spagetti sauce cans, 3-1/4" diameter. Mine gets 3x the signal of even my best vertical antenna, and mounting it appropriately on an old sattelite dish got 3x more than that, connecting to a hotspot over a mile away, once. Use as little coax as possible, usb adaptors can be directly attached, and can the bullet2hp, mine loves the cantenna. Those links should get you going on the right track, but the dimentions I gave you are as close as you will ever get to the perfect cantenna. The element needs to have 30mm exposed inside, and last, and most critical, is that the element needs to be 2.5 inches exactly, from the back or bottom of the can. Those work out to about 83mm, they are the only cans that are anywhere close, but they are perfect. The dimentions of these are critical to their effectiveness, the diameter should be between 80 and 90mm, I prefer the large us sauce cans, that are 3.25 inches (same as a tuna can), and the taller the better. Or tin can waveguides, I have built dozens of them. Posted: Tue 14:17 Post subject: I love cantennas Will this connection work? : modified bowtie dish antenna > wireless Linksys router WRT54GS > My computer via ethernet cable.Īnd if that will work, what settings do I need to put my router in? Client Bridged mode? Repeater? Repeater bridge? RP-TNC Pigtail? (N-connector to Linksys WRT54GS removable antenna slot)
A female N-connector (to mount in the antenna) thin copper sheet or copper plated circuit board 12 gauge copper wire? (to create bowtie) However, I'm still foggy on the exact materials and connectors: I plan on making the bowtie dish antenna setup instead of the more primitive cantenna. I currently have a WRT54GS v7.50.0 Wireless Router that was successfully flashed and upgraded to the latest version of DD-WRT. If anyone has any advice, links, etc that would help me in this project I would be much obliged.
CANTENNA CALCULATOR DOWNLOAD HOW TO
So, my project is to create an antenna of sorts (as cheap as possible) to increase my range.ĭoes anyone have experience creating and hooking up a homemade antenna to their router to receive free wireless internet? I am considering either the cantenna method (which I am still unsure how to do) or using an old direct tv dish in my backyard to fashion some sort of uber antenna. Unfortunately, I cannot see the network from my house. I live only 1 block away from the library and I have a clear line of sight to it from my window. I currently have no internet access where I live, so I am attempting to connect to the public library's unsecured wireless network. Alright, now that we're all clear, here's my project:
CANTENNA CALCULATOR DOWNLOAD UPGRADE
I did successfully upgrade my router with the DD-WRT firmware on the first try without bricking it. So if you throw some technical jargon into this thread please place a corresponding link, thanks.
I will be very upfront with everyone here by being the first to say that I have very limited technical skills when it comes to wireless networking. Posted: Fri 20:34 Post subject: Range Increase with Cantenna?
