I have a D-link Xtreme N 2.4GHz Antenna.  I need more cable to be within range of the wireless network.  I've been told the cable type is SMA.  I bought a 6m length of cable extension.  On it is printed "clf-200 low loss 50 ohm coaxial cable".  I am hoping to buy this cable type bulk along with male and femal connectors.  However, I can't find any information nor a place to buy this cable type!  Does anyone have more information?  Thank you!
