Velocity Factors are expressed as a percentage of the speed of light (i. The velocity factor is directly related to the permittivity of the transmission line. 8] Frequency 2. RG174 has a single shield and is not suitable for long-term outdoors use. For example, the velocity-range for. Measurement of VF is often taken as trivial, and the common technique is to find the lowest frequency at which the input impedance of a o/c stub is zero, and VF=PhysicalLength/ (c0/f/4)=PhysicalLength/ (299792458/f/4). 42. 0. RG174 50ohms: RG174 cable is very thin and flexible but high loss; the short lengths of cable that come pre-attached to indoor/portable antennas (like the popular 12" Magnetic Mount Antenna) are RG174. Assuming the velocity factor of the transmitted signal in a transmission line is around 11,760,000,000 inches per second, at 100,000,000 Hz the wavelength (λ) is 117. Includes calculated K and end.
