Selecting The Right Coax To Improve WIFI
http://onlywire.com/r/14693129 Coaxial cable for microwave (802.11 2.4 GHz WiFi) has to maintain the signal from your transmitter to your antenna without loss. Common Chinese made RG-58 from Radio Shack or other outlets is NOT the best you can do for coaxial cable and will lower your effective signal out! Used only for VERY short runs since it loses almost a DB per foot at microwave frequencies and is still very loss prone at CB freqs. Since thin cable has more loss for higher frequencies it is best to use only short lengths of LMR-240 LMR400 From Times Micro remains the best overall choice for best transmission line.
