Minimum path lengths for fixed links.
The distance between end points of a fixed link must equal or exceed the value set forth in the table below or the EIRP must be reduced in accordance with the equation set forth below.
|12,200 to 13,250
For paths shorter than those specified in the Table, the EIRP shall not exceed the value derived from the following equation.
EIRP = MAXEIRP − 40 log(A/B) dBW
Note to paragraph (b):
For transmitters using Automatic Transmitter Power Control, EIRP corresponds to the maximum transmitter power available, not the coordinated transmit power or the nominal transmit power.
Upon an appropriate technical showing, applicants and licensees unable to meet the minimum path length requirement may be granted an exception to these requirements.
Links authorized prior to April 1, 1987, are excluded from this requirement, except that, effective April 1, 1992, the Commission will require compliance with the criteria where an existing link would otherwise preclude establishment of a new link.
