Doug,

In response to your questions regarding our application please see the attachments added to the
application (since the PDFs cannot be copied into this text file). I have also emailed this information to
you directly.

For the horizontal antenna pattern, 0° on the plot corresponds to 128°N.
For the vertical antenna pattern, 0° on the plot corresponds to the horizon with the 30° peak
pattern gain being 30° below the horizon.

The application contains the worst-case ERP value using the signal generator maximum output and the
peak antenna gain. After refining our link budget, the signal generator will be operated at a much lower
peak output power of 1mW. The geometry of our test setup will also position the antenna to be pointing
30 degrees down from the horizon. Our peak ERP value on the horizon will be 0.575mW, given our
antenna geometry and loss budget between transmitter and antenna.

Your duty cycle calculations of 50% are correct. If the average power will be too high considering the
local FSS received earth stations nearby, please let us know and we’ll try to revise our test plan to
accommodate accordingly.

Thanks,
Brian
