One person mounted a small microwave antenna on my deck and readied the cabling. The other person installed a network card, analog modem, and a cable modem on my system and configured Windows 95 to handle the connection. Both people were courteous and graciously answered my technical questions about the service. The whole process took about 90 minutes. They set up my e-mail client and showed me how the system dialed the modem part of the connection automatically when opening Netscape, etc.
Installation requires some extra table space and up to three electrical outlets.
If you suffer from spaghetti-wire syndrome, prepare for more copper pasta on the back of your machine. The network card in your computer connects via RJ-45 cable to the cable modem. The cable modem is the administrator that tells your modem when to dial and collects the downloads from the microwave antenna. My antenna is about 4 inches in diameter and looks like a small lamp fixture. My fears about having a big dish bulging off of my deck were unfounded.
