This method can be used when the antenna symmetries are compatible with pattern multiplication, see Clause F.1.2.4. The procedure is as follows:

1. Calculate the reference angular steps as described in Clause F.1.2.

2. Align the EUT to allow for proper pattern multiplication. See Clause F.5. Measure EIRP on two orthogonal cuts with steps smaller or equal to the reference steps according to step 1.

3. Apply pattern multiplication according to Clause F.5 to extrapolate the two cuts data to full-sphere.

4. Apply numerical integration to obtain the TRP estimate as described in Clause F.5.
