i'm totally going to do this, and i think i just scored an extra direct tv dish too.
..make a dish into a highly directional antenna for the very popular IEEE 802.11 wireless networking. The resulting antenna has about 22 db of gain, and is fed with 50 ohm coaxial cable. Usually LMR400 or 9913 low loss cable is used if the source is more than a few feet from the antenna. The range using two of these antennas with a line of sight path is around 10 miles at full bandwidth.
10 miles!
use a primestar dish as an ieee 802.11 wireless networking antenna

(Page 2)22. an easier alternative is to use a USB 802.11 adapter in the focal point of the dish. Since the signal is turned digital by the USB adapter the only distance factor for signal loss is on the maximum length of the USB cable (50-100ft?), Probably cheaper than the cables and connectors.
24. Ooops. Never mind. "(You may use any old dish, but if it is bigger than the Primestar the gain will be higher, and it may not be within the Federal Communications Commission rules for use within the United States. In fact I have come to find out that there seem to be several different dishes that Primestar used, and I am only sure that the one I used, pictured above, used with the ordinary Wavelan or Airport transceiver card is within the effective radiated power limits given by the FCC.)"
25. So, where exactly can you find these old things? I've looked around in all the usual places (scrap heaps, garage sales, and dumps), but I haven't been able to find one. Are they available from the company? The seattle hacknight is out since I live in Florida...

26. you're in seattle right? If you want to build antennas, you should come to a seattlewireless hacknight. We do a fair bit of it and have the cabling, connectors, etc. If you're in-city, there's a good chance you can make a link with that thing.

28. I am attempting to create a primestar satellite dish that will receive wireless internet from an access point long range.
Is it possible for it to send AND receive?
if you have any information that i could use,
please send it to salemdavide@yahoo.com

21. Cantenna's are the _WORST_ feeds for the primestar dish. Try using a Bi-quad to feed the dish. I've picked up networks as far as 12mi with a Primestar dish feed with a bi-quad antenna and a 12mW 802.11b cheap-o card.
