This read-write object sets the transmit output power level in 0.1 dBm units, from -400 to 0, i.e., -40 to 0 dBm, with the description noting the CDM-570L variant's usable range is -40 to 0 dBm while the CDM-570 variant's is -25 to 0 dBm. This directly determines the RF power delivered toward the antenna's upconverter/BUC, so it must be set in coordination with the BUC's own gain and the link budget's required EIRP -- set too low and the far end can't achieve adequate Eb/No, set too high and it risks driving the BUC or the transponder into unwanted nonlinearity or interference with adjacent carriers. An admin performing a link budget calculation for a small remote antenna might set this to a modest negative dBm value into a BUC with substantial gain, targeting a specific EIRP the link budget calls for to reach the satellite with adequate margin.
