The receiver will send the LNBF 18 volts for horizontal polarity, and 13 volts for vertical polarity. For standard LNBs, the polarity is controlled by a motorized motor.
how much it will benefit , if at all dont know
Correct . i am telling that Horizontal Polarity needs more power to read/get full signals and Vertical needs less power. I am thinking that the same apply in Transponders to transmit/deliver the signals for uplinking and downlinking too .
My calculations may be childish but a doubt came to me. so thought about the chances .
