This hack or mod can send your internet access 10 miles and is surpirsingly cheap
Primestar was recently purchased by Direct TV who is phasing out all the Primestar equipment. This means that the dishes are being trashed, and are available for other uses such as the one I describe here. It is easy to make a surplus Primestar 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.
Would be good for boosting the signal to a workshop outside or a neighborhood, where you could be come your own ISP ;)
