Abstract
A method and system for determining parameters of a satellite signal present in a coaxial cable, the method comprising the steps of aligning two capacitive coupling sensors in proximity to a length of the coaxial cable, wherein the distance between the capacitive coupling sensors is below 10 centimeters; receiving from two capacitive coupling sensors a signal being a differential voltage in the coaxial cable between the locations of the capacitive coupling sensors wherein the voltage is relative to a voltage level in a coaxial cable; amplifying the differential voltage by a bandpass amplifier; detecting a valid DiSEqC command sequence being indicative of signal quality.
