Re:    DENALI 20020, LLC
       FCC Call Sign:    KA20

Dear Sir:

This letter is to confirm that the C-Band T/R Earth Station antenna licensed under call sign KA20 and
located near Brewster, WA (48-8-48.5 N, 119-41-32.2 W {NAD83}), under the ownership of DENALI
20020, LLC., has been under our continuous monitor and frequency protection service. We have been
monitoring all new frequency coordinations on their behalf and maintaining their participation in the
frequency coordination process as specified in part 25 of the FCC Rules and Regulations.

If you have any questions, or require additional information, please don’t hesitate to call me on (703)
726-5656 or by email at DMeyer@comsearch.com
