"The Institute of Radio Engineers has defined the INPUT SENSITIVITY OF
A RECEIVER as the number of microvolts required to produce standard
output when applied through a dummy antenna having the characteristic
impedance of the antenna with which the receiver is intended to
operate, to the input terminals of the receiver." Boonton, 1954
