Separation distances required to meet the compatibility conditions Separation distance between the transmitting end-UE and the broadcasting receiving antenna determined for broadcasting service fixed reception in rural environment for the line of sight conditions. The calculation was performed for different levels of out-of-band emissions (OOBE). Corresponding separation distances are shown in Table 24.
