EXHIBIT #5 for Modification of License WF2XCV submitted by ARTEMIS, INC. File # 0027-EX-ML-2013 CONCISE DESCRIPTION OF REQUESTED MODIFICATIONS In order to support testing for the Sea Dragon program, we have requested modifications to this existing experimental license in the following areas: Antennas Two new antennas are to be used in the planned testing phases. A smaller antenna will be used for initial low-altitude testing and a large, high-gain antenna will be used during the final testing stage. Both of these antennas have higher gain than the original license application described. The details of these new antennas are described in Exhibit #2: DIRECTIONAL ANTENNA INFORMATION Peak Transmit Power and Peak ERP The system to be tested is planned as a high-altitude, pulsed radar system. In order to obtain useful results, the transmit power requested on this license has been increased from that previously granted. We plan to use 25 W peak transmit power with the small antenna, resulting in a peak ERP of 2 kW, and 150 W peak transmit power with the large antenna which translates to 30 kW peak ERP. The duty cycle of the transmitter, however, is on the order of 4% which means that the average ERP is less than 1.5 kW for the high-power, high-gain case. The details of the transmitted signal are outlined in Exhibit #3: MODULATING SIGNAL DESCRIPTION. Occupied Bandwidth We have significantly reduced the bandwidth requested for this license modification. While testing the low-power, low-gain configuration, we will be limited to 9.15 – 9.85 GHz and when testing the high- power, high-gain configuration we will be constrained further to 9.3 – 9.5 GHz. These limits are outlined in the actual Form 442 submitted with the modification application. Geographical Location We have specifically requested permission to operate in a 20 km radius around Elberta, UT. This area is close enough to our base location to be accessible, but far enough from densely-populated areas to minimize the chance of harmful interference. It is understood that we would not operate outside of this requested radius.
