This value applies a transmit gain offset, expressed in a range from -400 to 0 and stored multiplied by 100, configured through the UGO= command, always reducing rather than increasing the nominal transmit gain. Admins use this fine offset to trim output power precisely without touching the coarser attenuation setting. For example, setting csat5060TxGainOffset to -150, representing -1.50 dB, slightly reduces transmit gain to fine-tune power delivered to the antenna beyond what the attenuation setting alone provides.
