Rockwell Collins, Inc. Call sign: WI2XZE File Number 0169-EX-CM-2017 Exhibit: Description of Modification and Antenna Sketches Rockwell Collins, Inc. (Rockwell Collins) respectfully requests a modification of its experimental license (WI2XZE), used to communicate command and control messages to unmanned aerial vehicles (“UAVs”) flying below 400 feet for beyond visual line of sight (“BVLOS”) research flights.. Rockwell’s modification seeks to add four new antenna locations to its approved license for additional testing. Antenna Descriptions and Sketches Rockwell Collins seeks to add four new locations to its license—two more in Illinois, and two more in Iowa. Two of the antennas will be mounted using cells on wheels (“COWs”); the other two will be mounted on existing towers. Iowa locations, Cells on Wheels For the two new mobile locations, the antennas will be mounted using COWs, as depicted here:  The Green Castle Airport COW, which will be located at NL 41-45-14.26, WL 91-43- 11.04, will be 50 feet tall, or 15.2 meters, from the ground to the tip of the antenna.  The Iowa City Airport COW, which will be located at NL 41- 38-18.97, WL 91-32- 26.02, will also be 20 feet tall, or 6.1 meters, from the ground to the tip of the antenna.
