Pc-case 0.5ft Rf Electrical Wire Connector Fakra "C" Plug to SMA Male Straight Assembly Extension Coaxial Cable Rg174 15cm for GPS Antenna SMA is designed for use from DC to 18 GHz, but is most commonly used for hand-held radio and mobile telephone antennas, and more recently with WiFi antenna systems and USB software-defined radio dongles. It is also commonly used in radio astronomy, particularly at higher frequencies (5GHz+). FAKRA* connectors have been especially designed to fulfill the tough requirements of the automotive industry. A sophisticated coding system of the standard plastic housing offers 13 mechanical and colored codings and one neutral coding. It has a frequency bandwidth, excellent performance, high reliability, long life characteristics application for Antennas, Wireless LAN Devices , Coaxial cable, Wi-Fi Radios External Antenna and so on Coaxial cable differs from other shielded cables because the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line.
