Antenna Factor for 100 Series EMC Probes Terry Noe, Beehive Electronics Introduction The tables below show the antenna factors for the Beehive Electronics 100 A/B/C/D. This data is identical to the graphical data that is also shown on the website. Magnetic Field Probes For the 100 A/B/C magnetic field probes, antenna factor is defined as: / A load impedance of 50 ohms is assumed. In the tables below, this is given in decibels: in other words: 20 The units of antenna factor are amperes per meter per volt, or A/(V*m). Electric Field Probe For the 100 D electric field probe, antenna factor is defined as: / A load impedance of 50 ohms is assumed. In the tables below, this is given in decibels: in other words: 20 The units of antenna factor are inverse meters, or 1/m. 100 A/B/C Magnetic Field Probes Frequency Antenna Factor dB(A/(V*m)) MHz 100B 100A 100C 0.3 98.47 76.67 56.25 1 88.77 65.77 45.55 3 80.17 56.47 36.15 10 70.17 46.27 26.05 30 60.77 37.77 18.25 100 50.87 27.97 11.85 200 45.67 22.67 10.45 300 41.77 18.47 12.65 400 38.57 15.37 17.65 500 35.87 13.97 30.95 600 34.97 13.17 12.25 700 34.17 11.77 5.65 800 33.07 10.47 900 31.47 10.67 1000 30.27 11.07 1100 30.17 11.07 1200 29.67 10.77 1300 28.67 11.17 1400 27.37 12.27 1500 26.87 12.87 1600 27.27 12.37 1700 26.87 12.27 1800 25.37 13.57 1900 24.47 14.87 2000 25.17 14.87 2100 25.27 14.67 2200 24.07 15.87 2300 23.17 17.47 2400 23.57 18.57 2500 23.67 20.27 2600 23.07 25.47 2700 22.67 25.27 2800 22.57 11.97 2900 22.57 1.27 3000 22.97 2.47 3100 23.27 3200 22.57 3300 21.97 3400 22.97 3500 23.77 3600 23.07 3700 22.07 3800 23.07 3900 24.37 4000 24.37 4100 23.27 4200 22.97 4300 24.17 4400 25.37 4500 24.97 4600 22.67 4700 23.37 4800 25.57 4900 24.17 5000 23.07 5200 25.77 5400 27.17 5600 26.87 5800 29.27 6000 28.67
