that gentleman knows what he's talking about. I am a hobbyist high-power (even sometimes slightly illegal power) wifi tech, and getting 2.4Ghz rated coax is a must. not even old thinnet coax will keep attentuation levels low enough to make the antenna an antenna. I personally buy all my wifi supplies with the exception of radios and APs from Hyperlink Technologies. They have good prices.
