Annex 1 - Method 1: Minimum
separation distance curves based on Recommendation ITU-R P.452, utilizing FSS earth station
height and e.i.r.p. density toward the
horizon, latitude, and possibly terrain heights
Annex 2 -
Method 2: pfd contours based on actual terrain data, the propagation model
in Recommendation ITU-R P.452-11, the
FSS earth station’s e.i.r.p. in 10 MHz
bandwidth and the diameter and height above ground of its antenna

site-specific analysis
1 General
2 A description of Method
3
Annex 4 -
Additional considerations for small and narrow countries to meet the
criteria of RR No. 5.502 and/or as a basis
for the establishment of bilateral
agreements to exceed the limits of RR No. 5.502
1 General
2 Restrict operation in
the 13.75-14 GHz band to medium or low e.i.r.p. carriers
3 Apply local
site-shielding to earth stations
4 Selection of earth
station antenna diameter
5 Seek bilateral
agreements to exceed the pfd limit
6 Seek bilateral
agreements to waive the pfd limit for part of the band
