For BSS antenna of diameter 240 cm, in addition to the above aggregate 100% of the time epfd limit, a −167 dB(W/(m2 · 40 kHz)) aggregate 100% of the time operational epfd limit also applies to receive antennas located in Region 2, west of 140° W, north of 60° N, pointing toward GSO BSS satellites at 91° W, 101° W, 110° W, 119° W and 148° W with elevation angles greater than 5°. This limit is implemented during a transition period of 15 years. 3 For this Table, reference patterns in the Annex 1 to Recommendation ITU-R BO.1443 shall be used only for the calculation of interference from non-GSO FSS systems into GSO BSS systems.
