hello guys i know that downlink from satellite to home DTH equipment is possible but is uplink from DTH home Equipment to satellite possible???since i heard that you need huge setup to uplink to satellite. and i have been seeing this LOOP OUT connector back in my STB what is the use of this connector??? and as we subscribers are given individual SIM cards what actually is there inside the card??what i mean is how much amount of information can a possible SIM card hold in a normal DTH SIM card. Thanks!
