Antenna Characteristics SDT 5000 050-002-0024R01 WIRELESS MATRIX CORP. PROPRIETARY AND CONFIDENTIAL November 17TH 2005

Wireless Matrix Corporation 050-002-0024 SDT 5000 Antenna Characteristics The SDT5000 uses an integral Dual Patch, medium gain, right-hand circularly polarized antenna with a maximum gain of 11.7dBi, over the entire transmit band including cable loss. Over the receive band the gain is 10dBi. The antenna noise temperature is typically 85K @ 35° elevation. The beam -3dB bandwidth in elevation is approximately 40°, (+ - 20° from the boresight of the antenna). The azimuth -3dB bandwidth is 62°, (+ -31° from the boresight of the antenna). The antenna pattern plots are attached for reference, see Figure 1 to Figure 4. Figure 1 Dual Patch Antenna - Receive Gain Wireless Matrix Corp Proprietary and Confidential
