2.7.2 Calculating the Required Transmit Power
The Link CX-24 will normally use the maximum transmit power listed in Table 2.1, but may need to be
attenuated when there are other receivers beyond the remote Link CX-24 terminal (for instance, in a
mesh network). In this case, the professional installer must use the free-space calculation to determine
the actual Maximum Transmit Power to prevent interference.

Radio Link Planning
As described in Section 1.7, each radio link requires a Link CX-24 at each end of the link. Before you start
installing the Link CX-24s, make a copy of Table 2.2 and fill in the information for both ends of the radio
