no wires, no signal. No workee.
If they wanted to look cool by having a satellite antenna, or give someone the impression that they had one, they should have gone a little farther to make it LOOK real. I’d find out who did this, ask them where they got such a contraption, or who makes it and they ask if they could see what kind of picture reception it gets.
This is a long range 2.4 ghz wireless antenna and don’t laugh at it cause this fella has probably never paid for internet access and probably never will, matter of fact I would guess it will work at least 2 mile on a weak home network.
Looks like a ham radio operator is experimenting. At least my ham radio station doesn’t look like crap!
Actually it looks like an ingenious design. Probably for wireless internet connectivity (steal a signal from someplace that provides connectivity for their customers.) A highly directional yagi-uda antenna using a found object (sat TV dish) for additional gain or shielding from an undesired signal in the opposite direction, and another found object (peanut butter container) to protect the driven element from detuning by snow/ice. I’d love to know how it’s working, and how much money they’re saving. By the way, note the coax under the dish.
maybe it’s a work in progress.
In my college network class we built a couple of these, we got out 1.5 miles give or take a little. A coffee can works better then a peanut butter jar.
I doubt it’s a stolen signal. The wireless providers are able to lock down your location via the electronics necessary to have the connection. It does look to me like a hi-speed wireless antenna that they put a dish behind to boost the signal. The peanut butter jar is probably just providing some weather protection for the connections.
I had a wireless antenna on my house for four years, and the signal was too weak with the antenna itself, so the technician put a dish behind it, and it boosted it enough to be a reliable signal.
I built a double bay Grey Hoverman antenna from PVC pipe, chicken wire, and copper wire. I get digital channels, over air, and the signal reception is excellent. Looks like wireless amplification for a 2.4 GHz High-Gain with hopes of dB gain from the dish here. Don’t know how that signal could get help from a parabolic reflector though?!?!
Go homemade science!
Having a background in sat+wifi I can confirm the 2.4 Ghz / dish-gain comments.. The real question is if he’s got it hooked to a decent amp.. otherwise they will see 1000 different wifi spots (incoming) but won’t be able to connect per his output, although concentrated, probably won’t be enough to negotiate..
But even with your standard router, a point-to-point connection can be easily several (5-10) Miles.
This setup is used often in 2nd/3rd world nations for connectivity –
Google wok wifi for more info.. The dish is actually a quite high end solution 🙂
I just hope the signal doesn’t get “jammed!”
