2. INTRODUCTION This report presents the test range data from four days of antenna testing by Optim Microwave, Inc. of the TracStar-i450M antenna performed at the ITT Loop Canyon far-field test range on October 6 through 10,2008. The goal of the measurements was to obtain as complete a set of measurements as possible on a production version of the antenna over the following parameters: • Three frequencies within the operational bands, • Transmit and receive bands, • Horizontal and vertical polarizations, • Co-polarized and cross-polarized patterns, • Elevation and azimuthally cuts, • Three elevation tilt angles. The results are presented in this report. i450M Antenna Gain Plots Proprietary and Confidential

3. Antenna Plots In this report the patterns are drawn normalized to the gain. The gain used is the measured gain. For these plots, a gain of 33.0 dBi is used. The envelopes shown on the plots are from FCC section 2.209 of “47cfr Ch. 1 (10/01/04) Edition”. The first envelope is for the plane in the geostationary orbit and is used for the azimuth plots: (1) Azimuth Envelope = 29 − 25 log (Θ) dBi, 1o < Θ < 7 o +8dBi, 7o < Θ < 9.2o 32 − 25 log (Θ) dBi, 9.2o < Θ < 48o −10dBi, 48o < Θ < 180o The second one is for all other directions and is used for the elevation cuts: (2) Elevation Envelope = 32 − 25 log (Θ) dBi, 1o < Θ < 48o −10dBi, 48o < Θ < 180o i450M Antenna Gain Plots Proprietary and Confidential

4. SUMMARY In this section the measurement results are summarized. The cross-polarized signal levels for the three elevation tilt angles are summarized in Table 1. The boresight cross-pol level is presented for both the azimuth and elevation cuts. The measured gain levels are summarized in Table 2. Note that the transmit gain is measured at the input to the type-N adapter and includes losses not included in the last measurement. Specifically it includes losses in: the type-N-to-SMA adapter, SMA-to-WR62 adapter, flex waveguide, waveguide adapter, rotary joint, low loss coax, and waveguide adapter.
