Why we use Transmission Line“When the length of the conductor is comparable to the wavelength of the signal, the conductor must be considered as a transmission line”
Transmission Lines allow us to have the same signal at various points in the RF network

Impedance of Coaxial Transmission Line
● Given two coaxial lines made from the same materials and with the same diameter outer conductor
● The cable with the smaller diameter center conductor will have a higher impedance
● The cable with the larger diameter center conductor will have a lower impedance

A word of Caution...None of the Cables listed in this section are suitable for use in repeaters or other duplex applications
The galvanic dissimilarity of the AL foil and the CU braid accelerates oxidation which creates a non-linear junction within the outer conductor of the cable.
This non-linear junction becomes and RF mixing point.
