FCC ELS Application Data for the HAARP IRI FRN: 0025173931 File Number: 0136-EX-PL-2016 Exhibit: Antenna Registration 1/22/2016 The IRI (Ionospheric Research Instrument) uses an electronically controlled phased array antenna system that has highly flexible phasing, beam forming and beam steering capabilities. The beam width and orientation can be set nearly arbitrarily within a cone above about 20 degrees from the horizon. The radiated beam characteristics are: Frequency, ERP, HPBW ERP in Watts 2.850 MHz ERP: 86.6 dBW 457.088 MW HPBW: 14.4 deg 3.400 MHz ERP: 88.1 dBW 645.654 MW HPBW: 12.1 deg 4.650 MHz ERP: 90.3 dBW 1.071 GW HPBW: 8.9 deg 4.995 MHz ERP: 90.8 dBW 1.202 GW HPBW: 8.3 deg 5.450 MHz ERP: 91.7 dBW 1.479 GW HPBW: 7.6 deg 5.950 MHz ERP: 92.6 dBW 1.819 GW HPBW: 7.0 deg 7.000 MHz ERP: 93.9 dBW 2.454 GW HPBW: 5.9 deg 8.100 MHz ERP: 94.5 dBW 2.818 GW HPBW: 5.1 deg 9.995 MHz ERP: 95.6 dBW 3.630 GW HPBW: 4.2 deg
