4. Directional Antenna Information — both Antenna locations Explanation The system being tested has multiple transmitter amplifiers and antennas for use at the various frequencies of operation. The table below shows the parameters for each frequency. The antennas are mounted on the test aircraft, which could turn to be pointed in any direction during the test. The antennas are mounted paralle! to the wings, which means in the vertical plane, the antennas are horizontal, except for a slight canted up or down depending on the angle of attack of the wing relative to the ground. (a) Width of beam in degrees at the half power point: See table below Operating Transmitter Transmitter Antenna Antenna Frequency Power Power Beamwidth Gain (GHz) (W) (dBW) (Degrees) (dBi) 0.435 100 20 80 7 3.3 200 23 34 15 4.6 200 23 34 15 5.6 200 23 34 15 9.3 125 21 16 20 (b) Orientation in horizontal plane: full rotation, 0 through 360° {c) Orientation in vertical plane: —10° to 10°
