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. The dish in use with Apple's Airport. Things You Will Need: A Primestar dish. Construction Steps: After deciding on a place to mount your antenna (which hopefully has a line of sight path to the access point or other IEEE 802.11 site), remove the apparatus at the feed position of the dish, saving the mounting hardware.

Lofted Space-Saving Furniture for Bedroom Interiors Tumidei is more than just a furniture company – they construct modern and relatively inexpensive (no, not cheap) pieces of furniture that they also create compositions from – interior design photos that you can use to shape your own space.
