Use a Surplus Primestar Dish as an IEEE 802.11 Wireless Networking Antenna Use a Surplus Primestar Dish as an IEEE 802.11 Wireless Networking Antenna
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. 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. I must stress the line of sight part though. Leaves really attenuate the signal.
