Revision of the Methodology for Processing Radio Noise Measurements in the Medium-Wave Band [Wireless Corner]

Issues Concerning Radio Noise Floor Measurements Using a Portable Measurement Set-Up

“…The antenna is matched to the characteristic impedance of the cable to the receiver and the receiver input impedance by an active circuit, often called an impedance convertor. Another example of a rod antenna is shown in [23]. The sensitivity of rod antennas is relative high with respect to broadband magnetic loop antennas, but the use of E-field rod antennas encounters a few problems as we will discuss below.…”

“…Although the recommendation gives a comprehensive overview of requirements for noise measurements in general, some more detailed aspects are depending on precise purpose and kind of the measurements. Other recent papers describe the study of indoor MMN in relation to digital broadcasting in the Medium Wave Band [22], [23], [24]. However, the measurement methods, as mentioned in these papers, use Electric(E)-field antennas without sufficient counterpoise and/ or grounding, resulting in large measurement uncertainties.…”

Cumulation of man-made radio noise: A quest for causes of the increase of radio noise in residential areas

“…An active circuit, often called an impedance convertor, matches the antenna to the characteristic impedance of the cable towards the receiver and to the receiver input impedance. Another example of a rod antenna is shown in [42]. The sensitivity of rod antennas is relative high with respect to broadband magnetic loop antennas, but the use of E-field rod antennas encounters a few problems as we will discuss below.…”
