APPENDIX F: PROTECTED FEDERAL GOVERNMENT SITES

The Federal Government, specifically DOD, operates and maintains extensive networks of radar, tactical radio relay, fixed microwave and aeronautical mobile systems across the entire radio spectrum. These systems are fundamental to the Federal Government in meeting their varying, essential communications requirements. Four specific frequency bands, the 1390-1400 MHz, 1427-1432 MHz, 1710-1755 MHz and 4635-4660 MHz, that will be reallocated for non-Federal use, provide for some of these essential communications requirements. Essential Federal operations in these bands are normally concentrated on a few sites across the United States. Protection to these sites is vital to minimize the impact that may be caused by non-Federal sector users to these essential and other Federal Government operations. As such, protection is afforded to sites across the United States at which essential operations are being conducted by the Federal Government in each of the four bands.

In particular, to protect essential operations in the 1390-1400 MHz band, high-valued Federal radar systems at the sites listed in Figure F-1 will continue to operate for nine more years. This will provide ample time for the affected agency to re-engineer existing channeling arrangements and possibly redesign, procure and install system replacements.

In the 1427-1432 MHz band, the Federal systems at the sites listed in Figure F-2 will continue to operate for 14 more years. This is appropriate considering the remaining useful life of Federal Government fixed microwave systems that have been purchased and contracted for. It also provides ample time necessary to redesign, procure and install replacement telemetry equipments.

For the 1710-1755 MHz band, a more stringent requirement is imposed to protect essential operations at sites listed in Figure F-3. Fixed microwave, tactical radio relay and aeronautical mobile stations authorized as of February 10, 1994 to Federal agencies at these sites will be retained indefinitely. Moreover, Federal Government operations conducted on these stations must be protected from harmful interference.

To provide sufficient time to re-engineer assignments on existing tactical and tropospheric scatter microwave equipment in the 4635-4660 MHz band, a minimum delay of three years in reallocating this band is necessary. However, essential Federal airborne operations at the locations listed in TABLE F-1 will be continued and must be protected from interference for 14 years.
