I've recently been asked by a friend to setup his new wireless internet. Since the contractor used by the IP wants $100 just for labor, he wants to buy all the equipment he needs from 3rd party vendors to try and save some money.
Now, in my humble opinion, I'd say I know maybe just a hair more about computers that the average layman, but I've never used wifi or anything wireless and consequently know nothing about it.
He lives less than 1000 ft from the tower and the install guy made it sould like he would need special equipment, which happened to be more expensive than the "standard" equipment "normally" used.
This would be for a one desktop home, so nothing fancy. I think I need an antenna, cable and USB adapter or PCI wireless card.
Is that the only equipment I need?
Do I need a special type of coaxial cable?
What type of antenna would work best for this application?
How do I "tune" the antenna?

Any and all help/comments will be greatly appreciated!
