The Computer VNA Assisted Measurements of the UTP Cable Transmitting Wide Range Frequency Signals up to 100 MHZ

The paper describes some possibilities of the Unshielded Twisted Pair (UTP) cable as an universal signal transmitting line at the range of radiofrequencies from 0,1 to 100 MHz. Four pairs of the UTP in the subject of the impedance of the line with the different load were examined. The Vector Network Analyzer was used as a base measurement equipment [1,2]. Results are clearly shown using charts from the freeware IG-miniVNA computer program. The final experiments conclusion presents the UTP 5e category as a good general purpose transmitting line for universal 100 ohm impedance sources and loads [3].
