 Posted: Sat May 21, 2011 1:27 pm    Post subject: Transmission line If a transmission line has a length greater than about 10% of a wavelength, then it will affect the circuit. My antenna L is 0.03125m + .7m of more wire ( I may not have that much wire ) from the transmitters line. Than L = 0.0315m + .7m = 0.7315m λ = 0.125m L is not >> λ so there is no transmission line problems. Does this mean there is no Impedance Matching problems aswell? Is Impedance Matching part of transmission line affect ?
