One of the principle factors that determine the effectiveness of an Rf based receive system is the antenna. The geometry of the antenna structure and the relationship to its counterpoise (i.e. ground plane) determine feed impedance and efficiency. Once the design parameters of the antenna have been established the input electronic circuitry is optimized for best sensitivity. If the antenna para- meters (geometry) deviate from the design intent the result will be measurable reduction in sensitivity.
